San Diego Sushi Tuna Found High in Mercury Toxic Tuna Trend Means Women and Children Must Avoid Tuna
The San Diego investigation follows on the heels of GotMercury.Org’s investigation of Los Angeles sushi in March 2006, which created international concern after a Los Angeles Times article.

"We are seeing a toxic trend here in California," said Eli Saddler, public health analyst for GotMercury.org. "Families in San Diego and across the nation need to know the risks of eating tuna sushi and avoid it for the sake of their children. With so many healthier seafood choices available, why take the risk?"
The FDA data reports that fresh and frozen tuna averaged 0.383 ppm, significantly lower than GotMercury.Org's results showed an average of 0.584 from 32 samples in San Diego and Los Angeles – over 150 percent of the mercury levels reported by the FDA. Overall, 25 percent of tuna tested in the two cities exceeded the federal advisory level for women and children. About 16 percent of the tuna tested – 1 in 6 tuna sushi – should not have been eaten by any consumer – man, woman, or child.
“In our combined studies, 1 out of 4 tuna sushi tested exceeded what is considered safe by the federal government,” said Eli Saddler, public health analyst for GotMercury.Org. “This new round of testing affirms the need for women of childbearing age and children to avoid tuna served as sushi, sashimi, or ahi.”
The FDA and EPA already warn women and children not to eat king mackerel (0.730 ppm), swordfish (0.970 ppm), shark (0.988 ppm), and tilefish (1.45 ppm). However, the FDA advisory on tuna is confusing and weak regarding tuna and differs from the calculations used by the EPA.
"Mercury contamination is a serious issue for pregnant women, children, and women who are even considering getting pregnant," said Erin Thompson of Women's Voices for the Earth. "Women buy tuna for themselves and their children. Therefore, it is absolutely critical that women be informed about what types of tuna to avoid, and it the responsibility of the FDA to provide this information."
Consumers are at risk by eating tuna sushi or sashimi and should be aware of the risks, especially women who are or intend to become pregnant, nursing mothers, and children. Children developing in the womb and young children are particularly vulnerable to methylmercury, the toxic organic form found in fish, because it can harm neurological development – resulting lower IQ, nervous system damage, cardiovascular ailments, and motor skill problems.
“Sushi can be part of a healthy diet, but consumers need to know that too much tuna can be toxic,” said Eli Saddler, public health analyst for GotMercury.Org. “Given that samples vary widely in mercury levels, there is no way to know how much methylmercury you are ingesting when you eat tuna sushi, sashimi, or ahi.”
GotMercury.Org is a free, online mercury-in-seafood calculator that was recently revised to include the FDA’s 2006 mercury in fish and shellfish data. GotMercury.Org educates consumers on healthier seafood choices by using the EPA and FDA data to calculate how much seafood consumption is safe in a given week.
