Mercury in Tuna Prompts New Call to Limit Intake - NYTimes.com
“White” tuna generally contained more mercury than “light” tuna, but some light tuna contained enough that a woman of childbearing age eating less than a can a week would exceed federal recommendations for mercury consumption, the new Consumer Reports study says. The metal can affect fetal development.
The average amount of mercury found by Consumer Reports in white tuna samples was 0.427 parts per million, compared with the average 0.353 p.p.m. found in F.D.A. tests in 2002-04. The average in light tuna was 0.071 p.p.m., lower than the 0.118 p.p.m. found by the F.D.A.
