In Reply to: Re: NOR98-LIKE STRAIN OF SCRAPIE FOUND IN WYOMING update posted by TSS on April 18, 2007 at 2:31 pm:
Dr. Walt Cook, acting state veterinarian, said the government would pay the
livestock owner an indemnity fee based on fair market value for the sheep,
before "depopulating" the herd.
"It's the best and the simplest thing to do," Cook said. "It's unfortunate
to put down all those sheep, but it will allow us to test them and make sure
no other animals are infected."
confusious is still confused, why did the USDA/FSIS/APHIS not take the same action with the atypical BSE BASE cases in Texas and Alabama. as with this NOR98 atypical scrapie, they have no idea if it will spread vertical or horizontal i.e. spreading via birthing or the environment via salvia, urine, feces, soil etc etc. ??? considering BASE is more virulent to humans, it just might be more virulent in other ways i.e. vertical and horizontal ??? and the fact that the BASE is sporadic CJD in humans, rather than the nvCJD, this makes absolutely no sense to me. ...tss
7. WHY is it that the Farm of the Mad Sheep of Mad River Valley were quarantined for 5 years, but none of these
farms from Texas and Alabama with Atypical TSE in the Bovine, they have not been quarantined for 5 years, why
not, with the real risk of BSE to sheep, whom is to say this was not BSE ?

5.0 Response to Disease Outbreak
When the Deputy Administrator of VS and the Administrator of APHIS
concur with the diagnosis of a presumptive case of BSE, the Response and
Notification/ Briefing section of the BSE Response Plan will be
Because BSE is not known to be contagious or vector borne, a declaration
of national emergency is not automatically necessary but may be
requested if warranted by the particular circumstances of the outbreak.
5.1.1 Checklist of Notification Actions Upon Diagnosis of BSE
See Response and Notification/Briefing sections of BSE Response Plan.
5.2 Declaring an Emergency
Because BSE has an extremely long incubation period, is not a herd
disease, appears to be transmitted primarily by contaminated
ruminant-origin rendered feed ingredients, and is not known to be
contagious or vector borne, an outbreak of the disease is not an
The declaration of an animal disease emergency need not be automatic. To
avoid undue public alarm, an emergency should not be declared unless
indicated by the particular circumstances of the BSE outbreak.
The Secretary of Agriculture has authority under the Federal Act of July
2, 1962 (Title 21 U.S. Code, 134-134 h) to declare an emergency when a
disease exists that constitutes a threat to the livestock or poultry
industries of the United States. Title 9, Code of Federal Regulations
(CFR), Part 76 contains regulations issued under this and other
Declaration of an animal disease emergency authorizes the Federal
Government to control and eradicate the disease problem and allows the
Government to seek funds from the Commodity Credit Corporation (CCC) and
other sources, to expend funds, and to place Federal quarantines on the
interstam movement of animals and animal products.
When appropriate, the Secretary would issue a formal declaration of
emergency. All affected States would be notified and expected to
cooperate by signing a Memorandum of Understanding (MOU) with the USDA
specifying actions and responsibilities for activities such as
surveillance, quarantine, indemnity, and seizure of animals. Both
Federal and State quarantines may be used simultaneously.
The most probable reason for declaring a BSE animal disease emergency
would be the inability to obtain funds for BSE-related activities in any
other manner, such as from the Secretary's contingency fund. Because BSE
outbreaks do not spread rapidly, adequate time to seek funding from the
usual sources or to prepare a budget request to Congress should be
BSE Red Book 2.1-27
5.3 Declaring an Extraordinary Emergency
Under authority of the Act of July 2, 1962 (21 U.S. Code 134a, 134b,
134d, and 145f) the Secretary of Agriculture may declare an
extraordinary emergency when adequate measures to control a disease are
not being taken by thc State involved. These acts authorize the Federal
Government to quarantine portions of a State, to enter premises after
obtaining a warrant, and to seize and destroy animals if necessary to
control the disease. It would seldom be necessary to declare an
extraordinary emergency for an outbreak of BSE, except to obtain
5.4 Authority To Pay Indemnity
Under provisions of Title 9, CFR, Part 53, USDA has the authority to pay
the fair market value or up to 100 percent of the expenses to purchase
and dispose of animals and materials required to be destroyed due to an
FAD (BSE), depending on the availability of funds for that purpose.
Because BSE can be transmitted through rendered animal products,
CNS-suspect animals must not be sent to slaughter. In the event of a
confirmed diagnosis of BSE or a presumptive diagnosis, notify FDA, CVM
if carcasses have moved to rendering or animal feed manufacturing.
Funds at 100 percent of the slaughter value at the time the suspect
animal is surrendered to the Government may be paid for suspect animals,
*The animals are surrendered voluntarily to USDA for euthanasia and
disposal, or for research, observation, and diagnostic purposes;
*The owner agrees to cooperate with all BSE epidemiologic
investigations, diagnostic procedures, and disease preventive measures
considered necessary by APHIS; and
*The Secretary of Agriculture or anthorized representative agrees to
At the beginning of a BSE outbreak, it is strongly recommended that
APHIS choose to purchase all animals in an infected herd for research,
observation, or depopulation.
5.5 Inspections and Seizures
Authority is provided under Section 5 of the Act of July 2, 1962 for
Federal and State inspectors (when specifically designated by the Deputy
Administrator of VS) to stop vehicles carrying bovids, make inspections,
and seize animals and other items to prevent the transmission and spread
of an FAD (BSE).
The applicable authority, 21 U.S. Code 134d, states that:
"Employees of the Department of Agriculture designated by the Secretary
for the purpose, when properly identified, shall have authority:
BSE Red Book 2.1-28
"To stop and inspect, without a warrant, any person or means of
conveyance, moving into the United States from a foreign country, to
determine whether such person or means of conveyance is carrying any
animal, carcass, product, or article regulated or subject to disposal
under any law or regulation administered by the Secretary for prevention
of the introduction or dissemination of any communicable animal disease;
"To stop and inspect, without a warrant, any means of conveyance moving
interstate upon probable cause to believe that such means of conveyance
is carrying any animal, carcass, product, or article regulated or
subject to disposal under any law or regulation administered by the
Secretary for the prevention of the introduction or dissemination of any
communicable animal disease; and
"To enter upon, with a warrant, any premises for the purpose of making
inspections and seizures necessary under such laws and regulations. Any
Federal judge, or any judge of a court of record in the United States,
or any United States commissioner, may within his jurisdiction, upon
proper oath or affirmation indicating probable cause to believe there is
on certain premises any animal, carcass, product, or article regulated
or subject to disposal under any law or regulation administered by the
Secretary for the prevention of the introduction or dissemination of any
communicable animal disease, issue warrants for the entry upon such
premises and for inspections and seizures necessary under such laws and
regulations. Such warrants may be executed by any authorized employee of
the Department of Agriculture."
Since BSE is infectious but not a contagious disease under normal
circumstances, it will rarely be necessary to stop vehicles or seize
animals and other related materials.
5.6 Other Authorities
Authorities for the control and eradication of diseases and pests of
livestock and poultry are changed from time to time. Consult the Office
of the General Counsel, USDA, and the Federal Register for authorities,
rules, and regulations.
BSE Red Book 2.1-29
6.1 Authority To Quarantine
State and Federal regulatory officials have authority to impose
quarantines or hold orders. Usually, State quarantines are imposed on
individual herds and premises when any foreign animal disease is
suspected. Control of intrastate movement is by application of State
authority. It is important to coordinate efforts with State officials. A
survey of all State Veterinarians in the United States was conducted,
and all agreed to use quarantine authority on a herd in their State in
the event that BSE was diagnosed.
In contrast, Federal quarantines control the interstate and
international movement of diseased livestock. Only a declaration by the
Secretary of Agricultare of an Extraordinary Emergency will provide
Federal authority to control livestock movements within a State. Federal
and State quarantines may be used simultaneously.
6.2 Suspected Premises Quarantine or Hold Order
When BSE or any foreign animal disease is suspected, the investigating
veterinarian or FAD diagnostician should decide the issuance of a State
quarantine or a hold order on the promises. The slow onset and
progression of clinical signs will often require that an individual
suspect animal be held and monitored for several weeks. Although BSE is
not a rapidly spreading disease, the suspect animal or any other
potentially infected carcasses must be kept out of the animal and human
food chains and rendering channels. The reason for the issuance of the
quarantine should be listed as a CNS suspect.
6.3 Affected Premises Quarantine
When there is presumptive diagnosis of BSE, movement of all bovine
animals on and off the promises should be restricted to allow time for a
thorough epidemiologic investigation. A hold order or quarantine
indicating the number, age, sex, breed, and identification of all bovine
embryos, ova. and semen supplies should be completed. No bovine animals,
embryos, ova or semen from the affected premises shoald be sold,
slaughtered, or rendered.
Although the role of maternal transmission in the spread of BSE has not
been fully determined and epidemiologic evidence suggests that maternal
transmission may not be significant, cow-to-calf transmission cannot be
ruled out. Hence, until more conclusive scientific evidence either
confirms or refutes maternal transmission, precautions (an extended
quarantine or other movement restrictions) to prevent disease spread via
this route are prudent. At this time, natural progeny of the
BSE-affected cows need to be traced and should be purchased. This
recommendation may be modified if scientific research data become more
October 1998 2.1-30
BSE Red Book
It is strongly recommended that the Government (APHIS) purchase all
cattle in the herd. No cattle from this herd shall be rendered. Tissues
from cattle dying of neurologic or prolonged wasting condition should be
submitted to a diagnostic laboratory.
If the herd of birth and the herd of last residence of the infected
animal are different, an investigation should be done to determine if
husbandry practices in the herd of birth are the likely source of
infection. Under certain circumstances, a quarantine (or other movement
restrictions) of this herd may be warranted until the epidemiologic
investigation is completed.
6.3.1 Affected Premises Security
Record the number and permanent identification of bovine animals,
embryos, ova and semen at the time of the quarantine or hold order.
Animals should not be allowed to move unless permitted by a State or
Federal animal health official. Introduction of new bovine animals to
the premises should be discouraged.
Because BSE is not a highly contagious disease, the need to post police
or other monitoring personnel is not obligatory.
Restriction of movements of non-Bovidae animals and vehicles or
inanimate objects must be determined on a case-to-case basis. However,
normal biosecurity and sanitary precautions should be observed.
6.3.2 Procedures on Affected Premises
A detailed epidemiologic investigation (sec. 4) should be performed on
all premises where BSE-confirmed animals are found.
Evidence from the United Kingdom has shown that the clinical
manifestation of BSE in any given herd is usually confined to a single
animal or a small group of animals. Although another suspect is unlikely
to be found, all cattle should be examined.
If another suspect is identified, that animal should have tissues
collected and submitted for diagnostic purposes after clinical signs
have sufficiently progressed. Carcasses of BSE-confirmed or suspect
animals should be incinerated.
Because BSE is not known to be highly contagious or vector borne, herds
found to contain a confirmed BSE case may or may not be depopulated.
Depending on circumstances, the government may purchase all animals
(suspect and exposed animals) for destruction or research purposes.
Embryos, ova, and semen from herds with confirmed BSE animals should be
held until an epidemiologic investigation is completed and the hold
order or quarantine is removed.
Milk from healthy animals in herds that have had BSE-confirmed animals
may be used for consumption, but milk from BSE suspects should be
withheld and disposed of in an environmentally acceptable method. Public
health authorities should be informed of the herd's BSE status. Litter,
bedding, feces, and urine from herds that have had BSE-confirmed animals
is not likely to be infectious. However, materials should be disposed of
according to good husbandry practices.
Feeds or feeding ingredients do not need to be destroyed simply because
they were near (or in contact with) suspect or confirmed animals.
However, if it is determined that feeds or feed ingredients contain
rendered animal protein originating from suspect or confirmed animals,
or that the feed or feed ingredient has
BSE Red Book 2.1-31
been epidemiologically linked to known BSE outbreaks, then the feeds or
feeding ingredients should he destroyed and disposed of by incineration.
Other steps that should be adhered to are the following:
*Federal, State and local policies concerning the feeding of rendered
ruminant or other mammalian protein to ruminants should be closely
*In light of recent preliminary research findings concerning maternal
transmission, farmers should be advised to promptly remove and
incinerate or bury placentas from calving pens. Calving pens should be
cleaned and disinfected. The disinfectants of choice are 4-percent
sodium hydroxide or 2-percent available chlorine.
6.4 Establishment of Quarantine Zone or Buffer Zone
Epidemiologic evidence indicates that the primary route of BSE
transmission is via infected meat and bone meal that is used in the
rations. Thus there is no need to establish a quarantine or buffer Zone
surrounding the affected premises.
6.5 Quarantine of Public Livestock Concentration Points
Livestock concentration points should be notified and employees should
be educated concerning the clinical signs of BSE. Any animal exhibiting
signs indicative of the disease should be reported. All bovids showing
evidence of neurological disease should be placed in an observation
facility within the premises. If the clinical signs are sufficiently
advanced, the animal should be euthanized and its tissues should be
submitted for examination. The carcass should be incinerated or buried
and must not be rendered. Due to the modes of disease transmission,
there is no need to quarantine livestock at concentration points.
6.6 Quarantine at Slaughter Plants
BSE is not known to be contagious or vector berne. Therefore, it is not
necessary to quarantine slaughter plants. Food Safety and Inspection
Service and slaughter-plant employees should be notified and educated
concerning BSE. Any animal exhibiting signs suggestive of the disease
should be reported. All CNS suspects should be isolated in a facility
where the animals can he adequately observed. The animal should be
euthanized and tissues submitted for examination. The carcass should not
permitted to enter the human or animal food chain. If laboratory
diagnostic tests have ruled out BSE the carcass may be rendered. In the
event of a presumptive diagnosis or a confirmed diagnosis of BSE, notify
FDA, CVM if carcasses have moved to rendering or animal feed
BSE Red Book 2.1-32
6.7 Moratorium on Animal Movements
No moratorium on the movement of animals (except as required by the
provision of the quarantine on affected herds) is necessary. However, if
animals from the same herd are presented for slaughter, those carcasses
should be held. Consult VS, Emergency Programs staff.
6.8 Veterinary Practitioners Operating in a Quarantine or Buffer Zone
A quarantine zone or buffer zone is not necessary in case of a BSE
outbreak, but the area must be geographically identified if the BSE
cases were domestic cases; similar feeding practices in the area may be
a risk factor. Veterinary practitioners throughout the United States
should be alerted and encouraged to report all animals with suspicious
signs. The Regional Emergency Animal Disease Eradication Organization
(READEO) director and the local AVIC or designated personnel should have
the responsibility for notifying all private practitioners in the
outbreak area after consultation with Emergency Programs staff.
Guidelines for working with a CNS-suspect animal or a BSE-affected herd:
*Practitioners should immediately report to regulatory authorities any
animal showing signs suggestive of ESE.
*Practitioners should wear clean coveralls and boots on each premises
*If performing a caesarian section, assisting with the calving of a BSE
suspect, or performing this work on an infected farm, the practitioner
should wear gloves and eye protection.
*If no FAD deagnostician or pathologists are available and the
veterinary practitioner must remove the brain of a CNS suspect for
diagnostic submission, every precaution should be taken to prevent
exposure of the skin or mucous membranes because rabies cannot be ruled
out. Practitioners should record all clinical signs and their
Veterinarians who need to visit premises under quarantine for BSE should
be allowed to do so and should observe normal disease control
precautions. They should wear clean overalls or similar apparel and
rubber hoots. Boots should be cleaned with an approved and registered
disinfectant before entering and when leaving a premise. Thermometers,
restraint devices (tongs), and other equipment should be disinfected
between premises as other contagious diseases cannot be ruled out.
6.9 Artificial Insemination, Germ Plasm Collection, and Embryo Transfer
The role that germ plasm plays in the transmission of the spongiform
encephalopathies, especially BSE, is still unclear. Studies involving
bovine semen and embryos are in progress and to date have revealed no
evidence of playing a role in the transmission of BSE. Due to recent
experimental evidence that scraple
BSE Red Book 2.1-33
may be transmitted by embryos, precautions against BSE transmission by
ova and embryos are reasonable (Foster et al. 1992 and 1996). All semen,
ova, and embryos produced by BSE--confirmed animals should be located,
inventoried and destroyed if the owner is agreeable. If an owner of
semen, ova, and embryos from a BSE-confirmed animal is not willing to
have these materials destroyed, guidance must be sought from VS,
Emergency Programs staff at once. Field personnel should not offer
indemnity for semen, ova, or embryos unless authorized by Emergency
Normal reproductive activities, including semen and ova collection,
natural and artificial insemination, and embryo transfer, may be allowed
to continue during the quarantine period on premises that have had
BSE-confirmed animals. However, movements of semen, ova, or other germ
plasm collected on the premises with confirmed cases of BSE should be
restricted until the quarantine is released.
6.10 Animal Protein Preservation
The carcasses from BSE-affected animals must not be used for human or
animal consumption. Dispose of carcasses by environmentally acceptable
methods, preferably incineration or deep burial. Consult VS, Emergency
Programs and public health authorities if necessary.
6.11 Controlled Slaughter of Potentially Exposed But Clinically
Cattle from premises under quarantine for BSE should not be slaughtered
or rendered until the epidemiologic investigation has been completed and
the quarantine has been lifted. Depending on the findings, the herd may
be purchased for research or depopulation.
6.11.1 Control of Animal Products From Affected Premises
Even if public health regulations allow, utilization of products of
clinically healthy animals from quarantined premises should not be
transported and processed for human consumption (except milk) during the
6.11.2 Meat Products
Meat from BSE-suspect animals must not be used for human or animal
consumption or enter the rendering chain.
Federal, State, and national rendering policies and FDA regulations
concerning the use of viscera and rendered proteins in animal feeds and
human food must be followed. Cooperation from other Government agencies
involved, as well as the rendering industry, is very important.
BSE Red Book 2.1-34
6.11.4 Skins or Hides
Skins or hides from healthy or exposed animals are not a risk for
spreading BSE. Normal processing precautions should be observed.
Milk from BSE-suspect animals should not be used for human consumption.
Milk from clinically healthy animals may be pasteurized and used without
further restriction. Public health officials should be informed.
6.12 Adjacent Premises
Area spread of BSE by vectors or other methods is not known to occur.
Therefore, quarantine of adjacent premises is not necessary.
6.13 Guidelines for Zoologic Parks and Exhibitions
Zoologic parks where transmissible spongiform encephalopathies have been
confirmed should be handled in a manner similar to that of beef or dairy
farms. Confirmed operation of the park and public access may be
continued. Affected animals should be isolated and observed for the
progression of the clinical signs before a final disposition is made.
6.14 Quarantine Release
After the epidemiologic investigation has been completed and decisions
are made concerning the disposition of the herd, the quarantine may be
released. At the beginning of an outbreak, it is strongly recommended
that the Government purchase affected herds for research and

7.0 Emergency Operations
The section below would be implemented only after a first case of BSE is
confirmed in the United States.
7.1 READEO Activation
READEO activation will rarely be necessary for BSE outbreaks. Different
from most other foreign animal diseases and infectious diseases, BSE is
not a rapidly spreading, acute epizootic; is not thought to be
transmitted horizontally between animals within a herd, has an extremely
long incubation period, and usually affects only isolated single animals
or, at most, a few animals within herds. Because BSE does not spread
rapidly, the workload to investigate and manage most outbreaks should
not normally exceed the capability of existing local field personnel.
READEO activation should be considered only if the particular
circumstances of a BSE outbreak warrant. If field personnel feel they
are unable to manage a BSE outbreak, they should communicate this to
their Regional Director and VS, Emergency Program staff, who will
evaluate the need for READEO activation.
7.2 READEO Organization
If READEO is activated, a reference should be made to the revised READEO
Manual for further guidance on READEO organization and operations.
7.2.1 Office of the Director
When an animal disease emergency exists, the Task Force Directors are
responsible for the READEO activities. The directors immediately move to
the location of the outbreak and setup the READEO headquarters. Work is
coordinated with State officials of the States involved in the outbreak.
188.8.131.52 State Director--(Note: This is the new designation for the
Assistant Director.) Each READEO may have one or more State Directors
since each State where the disease outbreak is found will be represented
in the READEO by State officials designated by the State Veterinarian.
184.108.40.206 Emergency Program Officer--This individual, designated by the
Chief Staff Veterinarian of VS, Emergency Programs, provides liaison
between the READEO and the Emergency Programs at APHIS headquarters.
220.127.116.11 Public Affairs Officer--The Public Affairs Officer plans,
develops, supervises, and maintains information activities for the
18.104.22.168 Legal--The Legal Advisor provides counsel and assistance to the
22.214.171.124 Military--The U.S. Armed Forces Command will designate a senior
line officer to be the Military Support Officer on the staff of the
READEO Task Force Directon The individual is assigned to be the liaison
between the Depart-
BSE Red Book 2.1-36
ment of Defense and VS, Emergency Programs,and to coordinate needed
military assistance during eradication of an FAD outbreak.
126.96.36.199 Meat and Poultry Inspection Operations--The Meat and Poultry
Inspection Operations, Food Safety and Inspection Service, will
designate personnel to report to the READEO Task Director and to provide
liaison between the Task Force and the Meat and Poultry Inspection
188.8.131.52 Laboratory Coordination--The Laboratory Coordination Officer
will advise the READE(3 Director concerning laboratory capabilities and
appropriate laboratory examinations to be conducted to provide needed
results as rapidly as possible. This individual will assist with
interpretation of results.
The Administrative Officer assigned to the READEO will direct and
coordinate all facets of general administrative functions. Refer to the
revised READEO Manual for a detailed description of the organization and
7.2.3 Field Operations
The Field Operations Officer will direct line operations and supervise
field personnel in a READEO. Disease investigation, field epidemiology,
disease security and personnel security, animal movement control and
quarantine enforcement, appraisals of animals and materials,
depopulation and disposal, and cleaning and disinfection are among this
7.2.4 Technical Support
Staff support consists of a technically competent staff designed to act
as a resource for the READEO Task Force. Personnel may include but are
not limited to individuals who have expertise in the following areas:
animal welfare, data systems, disease reporting, economics,
environmental impact, epidemiology, evaluation, orientation and
training, risk analysis, and wildlife. The staff communicates the needs
of the Field Epidemiology Delivery System (FEDS) to the READEO Director
as required to maintain an efficient, accurate, up-to-date FEDS.
184.108.40.206 Animal Welfare---Animal Welfare Officers must be knowledgeable
about current Federal and State animal welfare regulations, humane
methods of animal depopulation, and socioeconomic concerns related to
animal welfare issues. They advise the technical support staff and field
operations concerning current procedures and accepted methods for use in
the humane depopulation of livestock and poultry.
220.127.116.11 Wildlife-- Wildlife Officers participate with the Director and
other officials of the READEO to establish and carry out wildlife
policies and objectives for the emergency animal disease operation.
Through familiarity with the topography, wildlife density, susceptible
wildlife species, and movements of susceptible wildlife, the Wildlife
Officers can review maps and make recommendations concerning areas to be
included in the quarantined high-risk and buffer zones. These officers
maintain contact with local, State, and Federal wildlife enforcement
officers and wildlife biologists. They develop strategies for conducting
surveys of susceptible wi!dlife in the outbreak
BSE Red Book 2.1-37
area to determine the incidence of the disease. They direct and
coordinate the vaccination and depopulation of wild animals as necessary
to eliminate the disease.
7.3 Supplies and Equipment
During an outbreak of BSE, supplies and equipment should be obtained
through normal procurement procedures. If a READEO is activated,
supplies and equipment should be ordered through the READEO Procurement
and Supply Officer.
7.3.1 General Field Supplies Guidelines
Refer to APHIS Directive 326.1, 10/10/77 and 221.1, 1/29/74.
7.4 Personnel Responsibilities
During a BSE outbreak, field personnel should follow instructions issued
through the normal chain of command. If a READEO is activated, personnel
should refer to the revised READEO Manual for detailed descriptions of
Personnel assigned to the READEO Task Force are individually accountable
for equipment and supplies checked out to them. They should order
replacement equipment and supplies or return equipment for repairs
through the READEO Procurement and Supply Officer. All damages or losses
to equipment or vehicles should be reported immediately to the READEO
Administrative Officer, and the required forms should be completed and
Employees of the READEO Task Force are responsible for recording and
preparing all travel-related documents. Claims for travel, lodging, per
diem, and incidental expenses should be submitted to the READEO
Administrative Officer for processing.
Employees of the READEO Task Force are responsible for operating,
cleaning, and performing routine maintenance of assigned vehicles. They
also are responsible for recording mileage, expenses, and services.
Required reports are to be submitted to the READEO Vehicle Officer.
7.4. 4 Clothing
Employees of the READEO Task Force are issued protective clothing to
wear when entering a premises where BSE has been diagnosed or is
suspected. Clean clothing should be worn on each premises. Employees are
responsible for laundering the clothing before reusing it.
BSE Red Book 2.1-38
In a large task-foree operation, arrangements may be made for a
commercial laundry service to handle the clothing. If it is possible and
practical, all clothing should be labeled to identify the employees to
whom it is assigned.
7.4.5 Miscellaneous Responsibilities
Employees are responsible for conducting their assigned tasks in a
professional manner. Complaints concerning task force employees should
be directed to the READEO Director for resolution or appropriate action.
All animals, products, and materials to be destroyed because of BSE
should be appraised according to 9 CFR 53.3 and appropriate State
7.5.1 Appraisal Teams
Appraisals must represent the interests of the owner, the State, and the
Federal Government and be consistent with fair market values. If State
authorities approve, State and Federal interests may be represented by a
VS employee alone. Owners may, at their discretion and expense, employ a
professional appraiser to advise them or to act as their agent. Either
the owner or the owner's agent must be present at appraisals.
No animals may be destroyed until after the appraisal forms are signed
by the owner or the owner's agent. Appraisers should be certain that the
owner or the owner's agent is aware of the indemnity form's clause
concerning liens and mortgages.
When the number of animals to be destroyed is small, and the total value
of animals, products, and materiais is low, APHIS field personnel may
negotiate the appraised value with the animal's owner without assistance
from a professional appraiser. The appraised value of a BSE suspect
should be the slaughter value of the animal, taking into account any
existing defects or diseases that would affect the slaughter value but
ignoring those signs that caused the animal to be classified as a BSE
suspect. If field personnel are in doubt concerning the need to use a
professional appraiser, they should consult their supervisor or VS,
Emergency Programs staff.
If a determination is made that healthy progeny, ova, semen, or embryos
must be destroyed, they should be appraised at 100 percent of
Feeds or feed ingredients located on suspect farms will rarely need to
be destroyed. If a determination is made that feeds or feed ingredients
must be destroyed (for example, to comply with a policy decision to
remove all rendered products from animal feeds), then these materials
should be appraised and indemn'ff~ed according to 9 CFR 53.3.
BSE Red Book 2.1-39
7.6 Depopulation Procedures
7.6.1 Factors and Considerations
If the owner is agreeable, a humane method of euthanasia of BSE suspects
will be necessary to facilitate the accurate diagnosis of the disease
problem, to ensure that the suspect animal is not slaughtered or
rendered, and to terminate the animal's suffering. Under no
circumstances may BSE suspects be sent fo slaughhter or rendering.
Notify FDA, CVM if you suspect that the carcass of a BSE-confirmed
animal has moved to rendering or animal feed manufacturing. The VS,
Emergency Programs staff, Riverdale, MD, must authorize the use of
euthanasia, depopulation, and indemnity payments for READEO operations.
7.6.2 Humane Euthanasia Methods
Only experienced veterinarians should perform euthanasia because there
are inherent dangers. Precautions should be taken to prevent accidents.
Owners should be given a complete explanation of what to expect, and
only humane euthanasia methods should be used. Euthanasia should be
performed away from public view, and, if possible, the owner should not
be present. Euthanized animals must be checked to confirm death. (See VS
Memo 583.1, 1992.)
18.104.22.168 Mechanical (Firearms)--Because the only acceptable method for
euthanizing an animal by using firearms is to shoot it in the head, and
because the animal's brain must be preserved to diagnose BSE, firearms
are not an acceptable euthanasia method.
22.214.171.124 Chemicals(Toxic Gas or Lethal Injection)--Follow guidelines
established by the American Veterinary Medical Association. When using a
regulated controlled substance (e.g., barbiturates), control and
administration of the euthanasia agent must be given by a veterinarian
having a Drug Enforcement Administration (DEA) number issued by the U.S.
Treasury. Control and administration of chemical substances for
euthanasia must be authorized by the AVIC unless directed by the VS
Deputy Administrator. (See VS Memorandum 583.1, 1992.)
7.6.3 Supervision of Depopulation
Field personnel should never perform depopulation or euthanasia without
explicit permission from their supervisor or, if appropriate, the READEO
Humane and Disposal Officer. (Refer to the revised READEC) Manual.)
7. 6.4 Permits for Movement
All BSE suspects may be moved under permit to facilitate medical
treatment, euthanasia, necropsy examination, or carcass disposal.
Permitted movement will be according to the quarantine restrictions and
will be administered by the State or Federal officials.
7. 6. 5 Security
Because BSE is neither contagious nor vector borne, strict disease
security measures are not necessary. Personnel should observe normal
disease security measures that are standard procedure for all farm
visits. The READEO's Security and Disease Prevention Officer has the
responsibility for establishing biosecurity measures.
BSE Red Book 2.1-40
Under no circumstances may BSE suspects be sent to slaughter or
rendering. Notify FDA, CVM if you suspect that the carcass of a
BSE-confirmed animal has moved to rendering or animal feed
manufacturing. Field personel should arrange for the carcass to be
transported to and examined by a qualified veterinary pathologist or
field veterinary medical officer. After the pathologic examination has
been completed and the necessary diagnostic specimens have been
obtained, field personnel should arrange for disposal of the carcass.
Before a method of disposal is selected, there are many factors that
must be considered, and often other State and Federal agencies must be
consulted. The environmental and legal impacts of the operation must be
considered. Upon recommendation of the State or Federal agencies, VS may
consider other disposal methods.
Incineration, although more expensive than burial, is the preferred
disposal method for BSE-suspect carcasses. Federal, State, and local
environmental regulations may restrict the use of this method and
permits may be necessary. As soon as BSE suspects are reported to APHIS,
field personnel should investigate the location and availability of
incinerators of sufficient size to process a bovine carcass.
Institutions likely to have incinerators include State and university
diagnostic laboratories, waste contractors, large municipalities, and
private industries. Ideally, the diagnostic laboratory where the
pathologic examination was done will have incineration facilities.
The BSE-suspect carcass disposal is APHIS' responsibility (not the
diagnostic laboratory's). Field personnel should arrange for
transportation and final disposal of the suspect carcass and should
inform their supervisors and/or the READEO Humane and Disposal Officer
of these arrangements.
Personnel should be aware that some laboratories dispose of carcasses by
rendering and should specifically inquire if this is the case. CNS
suspects should be incinerated or held from rendering until a diagnosis
of BSE can be ruled out. Under no circumstances may BSE susuects be sent
to slaughter or rendering. Notify FDA, CVM if you suspect that the
carcass of a BSE-confirmed animal has moved to rendering or animal feed
Field personnel should be prepared to accompany the carcass from the
farm of origin to the diagnostic laboratory and then to the disposal
site if any doubt exists concerning the final disposal method.
If there are no other avenues for carcass disposal, burial of
BSE-suspect carcasses may be an acceptable disposal method. APHIS field
personnel should inquire with environmental authorities concerning
Federal, State, and local regulations that may impose restrictions on
The burial site may be on the affected farm, at the diagnostic
laboratory where the carcass is examined, or in a local landfill. The
site should be inaccessible to animals, removed from populated areas,
not used for agricultural purposes, clearly marked, and properly
BSE Red Book 2.1-41
Burial sites should also be located a sufficient distance from
underground utility lines, septic systems, water wells, and surface
water. Local environmental or public works officers may be helpful in
locating a satisfactory site.
Field personnel should consult with their supervisors and/or the READEO
Environmental Impact Officer before digging. Burial trenches are
normally at least 9 feet deep with floor dimensions of 7 by 2 feet per
adult bovine carcass. Carcasses should be covered with at least 6 feet
of soil. This soil should not be tightly packed because gas formation
may cause a tightly packed trench to crack and leak.
Because BSE is spread by rendered animal protein, BSE-suspect and
confirmed carcasses must not be rendered, unless the rendered material
is incinerated. Notify FDA, CVM if you suspect that dead BSE animals or
carcasses have moved to rendering or animal feed manufacturing.
7.7.4 Other Disposal Methods
The AVIC, the State animal health officials, and the READEO Director may
recommend other methods of disposal to the Deputy Administer, VS, for
approval (9 CFR 53.4). Options for disposal must be discussed and
approved by VS, Emergency Programs staff and must comply with all State
and local Environmental Protection Agency regulations.
7.8 Cleaning and Disinfecting (C&D)
Although BSE is neither contagious nor vector borne, appropriate C&D is
required to prevent farm-to-farm transmission of most other infectious
diseases. Field personnel must remember, however, that at the time they
are requested to euthanize a BSE-suspect animal, a confirmed diagnosis
of BSE will not be available. Signs compatible with BSE may be caused by
numerous infectious diseases and many BSE-suspect animals will, in fact,
have some other disease. Although the C&D of items such as manure,
bedding, feed, stalls, halters, milking machines, and other supplies and
equipment that have been in contact with BSE suspects is not
specifically necessary to control BSE, C&D is still advisable to control
other diseases that may be present.
7.8.1 Procedures for Cleaning and Disinfecting
126.96.36.199 Premises and Items--Field personnel are not responsible for C&D
of premises such as barns, stalls, and animal pens unless invasive
diagnostic procedures (such as a necropsy examination or the removal of
the suspect animal's brain) were performed on the premises. If possible,
field personnel should avoid doing such procedures on the farm. If
circumstances require that such procedures must be done on the farm,
personnel should clean and disinfect the immediate area after completing
188.8.131.52 Vehicles--Vehicles used to transport personnel to affected
premises should be kept clean, and normal precautions against the
farm-to-farm spread of any disease should be observed.
BSE Red Book 2.1-42
7,8.1.3 Carriers--Thoroughly clean trucks and trailers transporting BSE
suspects. Manure and bedding may be disposed of by any environmentally
accepted method such as spreading on fields or composting. After
conveyances have been thoroughly cleaned, disinfectant should be sprayed
on the sides and floor of the truck bed.
184.108.40.206 Livestock Markets--The risk of BSE transmission at livestock
markets is negligible. If a BSE suspect is found at a livestock market,
it should be managed the same as if it were found at a farm. Because of
the high risk of transmission of diseases other than BSE, invasive
diagnostic procedures, such as a necropsy examination or removal of the
suspect animal's head, should not be performed at livestock markets. Due
to the recent research findings concerning maternal transmission, any
pens or areas in which calving occurs should be thoroughly cleaned and
Cleaning and disinfection is not necessary to prevent the spread of BSE.
However, the C&D procedures are recommended to prevent the spread of
other diseases from pens or buildings where BSE suspects were held.
220.127.116.11 Slaughter Plants--Becanse BSE is spread by rendered animal
protein in cattle feeds, BSE suspects must not be slaughtered nor
rendered. If a BSE suspect is found at a slaughter plant, it should be
managed similarly to finding a suspect at a farm.
7.8.2 Approved Disinfectants
Field personnel should use professional judgment in the choice of a
disinfectant. Preferred disinfectants to inactivate the BSE agent
include 1N sodium hydroxide solution or sodium hypochlorite solution
containing 2 percent chlorine (1 hour exposure at 20 %C [68 %F]). This
should be used whenever there is reason to strongly suspect that BSE is
in fact the cause of the suspect animal's disease. Such reasons include
previously confirmed BSE in the geographic area or signs more compatible
with BSE than with any other neurologic disease.
If the suspect animal's signs are more compatible with diseases such as
rabies or listeriosis, then a phenolic disinfectant such as "One Stroke"
may be preferable. (Refer to appendix A Survival of BSE Agent and sec.
7. 8. 3 Precautions
All disinfectants are hazardous to human beings, animals, and the
environment. Label directions should be carefully read and followed.
Many disinfectants, including sodium hypochlorite solution, are also
corrosive and should be used with caution on metal and other corrodible
materials. Thorough rinsing is necessary if corrosive disinfectants are
used on metallic items.
Disinfectants, especially in concentrated form, may irritate skin, eyes,
and respiratory systems. Protective equipment such as appropriate
clothing, rubber boots, rubber gloves, mask and goggles should be worn
during mixing and application of disinfectants. If areas of the body are
exposed to a disinfectant, they should be washed thoroughly with water.
Employees should notify their supervisor and their Health and Safety
Officer if excessive human or animal exposure to disinfectants occurs or
if there is accidental release into the environment.
BSE Red Book 2.1-43
Field personnel should use normal hygienic procedures (such as washing
and disinfecting boots and removing the outer layer of clothing) when
leaving the farm. Unless the disease problem is noncontagious, personnel
should not travel to other livestock premises for the duration of that
7.9 Vector Control
Current scientific data indicate that BSE is not spread by vectors.
7.10 Disease Prevention and Philosophy
The goal of disease prevention and control is to confine the occurrence
of BSE to as few herds as possible and to prevent recycling of the BSE
agent in the ruminant food supply. If undiagnosed cases are rendered and
included in ruminant rations, the long incubation period may allow many
animals to be exposed.
Action should be taken immediately after the detection and confirmation
of BSE to initiate an extensive epidemiologic investigation to determine
the source and extent of the disease, to stop the spread, and to
eradicate the disease.
7.10.1 Philosophy--Immediate action should be taken to prevent
contamination of the animal food supply by prohibiting rendering of any
infected or suspect bovine carcasses. In addition, care should be taken
to monitor those animals born and raised in affected herds and to
prevent their becoming a source of infection to other herds.
7.10.2 Agent Spread--Epidemiologic evidence indicates that the primary
route of BSE transmission is through the feeding of contaminated meat
and bone meal that has been manufactured using scrapie infected sheep
carcasses or BSE infected bovine carcasses. Recent research findings
suggest that maternal transmission may occur at a rate of approximately
1 percent in some species. It is believed that this route of
transmission is not significant enough to maintain an epidemic. Cases of
apparent maternal transmission have also been identified in captive
7.10.3 Control of Products and Conveyances--Carcasses of BSE suspects
should be incinerated. Carcasses must not be rendered and incorporated
in animal feed. If carcasses are transported for disposal, conveyances
should be cleaned and disinfected after use with either a sodium
hypochlorite solution (2 percent available chlorine) or 1 N lye (sodium
7.10.4 Control of Biologics and Drugs--Although no documented cases of
BSE have resulted from the use of biologics derived from bovines,
tissues from suspect or exposed animals must not be used for the
production of biologics and drugs.
The agents responsible for causing the transmissible spongiform
encephalopathies are highly resistant to normal inactivation processes.
Careful selection of source materials is the best way to secure maximum
safety of ingredients or reagents of bovine origin used in the
manufacture of biologics or other medicinals. Factors that should be
considered are the age of the animals, exposure to the agent, and the
tissue or organ from which the product is derived.
BSE Red Book 2.1-44
7.10.5 Wild Birds, Wind and Insects---Wild birds, wind and insects are
not known factors in the spread of BSE.
7.10.6 Rodents--Rodents are not known factors in the spread of BSE.
7.10.7 Hunting--Restrictions on the hunting of wild animals are not
necessary to prevent BSE.
7.10.8 Exhibitions--Cancelling scheduled exhibitions is not necessary.
7.10.9 Rendering Trucks and Drivers--The carcasses from BSE suspects
must not be rendered. If any rendering truck is used to transport a
suspect, it should be cleaned, washed, and disinfected as above. (Refer
to appendix A--Agent Survival and sec. 7.8.2--Disinfectants.)
7.10.10 Treatment--Currently there is no known treatment for BSE.
7.10.11 Prevention--Suspects and animals confirmed to have BSE must not
be rendered. Producers, feed mills, and rendering establishments should
adhere to U.S. State and local rendering policies and FDA regulations
concerning the feeding of rendered animal protein to ruminants. Because
of the possibility that some transmissible spongiform encephalopathies
may be transmitted at the time of parturition, precautions should be
taken to prevent exposure of healthy animal to placenta and reproductive
fluids. Importation of live animals and animal products from countries
with BSE or having high risk factors for BSE should be restricted based
upon scientific risk assessment.
18.104.22.168 Immunization--The agent that causes BSE elicits no detectable
immune response in the host. Therefore, vaccination is not a viable
option. There is no vaccine currently developed for BSE or other TSE's.
22.214.171.124 Sanitation--Although it is unknown whether a contaminated
environment plays any role in the spread of BSE, it is suggested that
pens having contained BSE-infected animals be cleaned and disinfected.
The disinfectants o choice are sodium hydroxide (lye) and sodium
hypochlorite, in infected herds it is also advisable that all placentas
be removed promptly and buried or incinerated. The calving pens also
should be cleaned and disinfected.
7.10.113 Producer Defense---The most effective way to prevent an
intruduction of BSE into a herd is not to feed ruminant byproducts to
ruminants. As of August 4, 1997, the FDA has a ban in place which
prohibits the feeding of most mammlian proteins to ruminants.
7.11 Records Maintenance in a Foreign Animal Disease Outbreak
The APHIS FEDS will be used by the READEO to record information. FEDS a
computerized network designed to transmit accurate information rapidly
during any emergency disease outbreak. The use of FEDS will allow the
READEO to direct its attention to the minute-to-minute business of
containing and eradicating the disease.
For an accurate record of the activities, all field supervisors in a
READEO task force should maintain a diary. Activities and observations
should be recorded in the diary when they occur. Date all documents and
enter events by time and date to show a correct chronology.
Enter events as they occur in the diary as well. An accurate history is
of considerable value in developing policies and plans for future
BSE Red book 2.1-45
programs, and it may be important if there is litigation. A diary will
be helpful for day-to-day administration of funds, personnel, and
equipment. It is also useful as a later reference in preparing reports
and summaries of activities.
7.11.1 Daily Reporls
Submit daily reports of significant activities to the READEO Director
and the VS, Emergency Programs staff Riverdale, MD. (Refer to appendix F
for current telephone listings.)
Include the following as part of the historical file of an outbreak:
*Maps showing premises where BSE-infected animals were found;
*Inventory of feeds and feed sources;
*Origin of BSE-suspeet and confirmed animals;
*Public information material distributed, newspaper clippings; and,
Administrative reports to support the expenditure of funds, utilization
of personnel and equipment, and disposition of excess materials and
equipment at the end of the program.
