Recommendations published in the magazine Consumer Reports this week urge women to avoid eating any canned tuna while pregnant because of uncertainties about the risk of mercury contamination to developing fetuses.
The recommendations are stricter than the federal government’s advice issued two years ago. Then, the FDA advised women and young children to limit — but not avoid — consumption of canned tuna because of contamination.
But the magazine’s experts say women should avoid the popular item altogether because of FDA data showing that some canned tuna may have higher mercury levels than once thought.
