Canadian health experts have cautioned about the risk of mercury in canned albacore tuna in women and children. They have also issued guidelines regarding the consumption of tuna in women and children. This follows a recent report from CBC which found out that 8 out of 60 cans of albacore tuna tested contained mercury more than the prescribed level.
According to this guideline, four servings of canned albacore tuna per week can be had by pregnant and breast feeding women, while it can go up to one serving per week in children in the age group of 1-4. Two servings of the same food can be had by children who are between 5-11 years per week.
These guidelines hold good only for canned albacore tuna. There are other varieties of canned albacore tuna also like skipjack, yellowfin and tongol, which are relatively low in mercury.
