 FDA's Recommendation on Mercury, Fish and Tuna
In March 2004, FDA and EPA revised its advisories on mercury in fish for pregnant women and young children. Generally they are advised to eat no more than 2 meals of low-mercury fish per week - one can of light tuna or half a tuna steak is considered one meal. FDA recommends to limit albacore white tuna to one meal per week as it is higher in mercury. So check the labels when purchasing canned tuna.
