The FDA and EPA say that women of childbearing age and young children may eat up to 12 ounces a week of light tuna or other “low in mercury” seafood, including, within that limit, up to 6 ounces per week of white tuna. Because our analysis of FDA data found occasional high mercury levels in light tuna, our fish-safety experts suggest a more cautious approach. Their advice, below, assumes that no other mercury-containing seafood will be eaten during the same week.
|Who||Limit per week|
|Children less than 45 pounds||
4 ounces or less of light tuna or 1.5 ounces or less of white (albacore) tuna, depending on the child’s weight. (Get more details on children and tuna consumption.)
|Children 45 pounds or more||
About 4 to 12.5 ounces of light tuna or 1.5 to 4 ounces of white tuna, depending on the child’s weight.
To be careful, avoid canned tuna. Choose a low-mercury fish instead.
|Women of childbearing age||
About 12.5 ounces of light tuna or 4 ounces of white tuna.
|Men and older women||
About 14.5 ounces of light tuna or about 5 ounces of white tuna per week should be OK, but people who eat fish more often would be prudent to stick to low-mercury types.
