Levels of Mercury in Tuna Cans Inconsistent, Says Consumer Reports
Consumer Reports (CR) recently tested canned tuna from popular brands, and observed varying levels of mercury, a toxic heavy metal found in foods, on a can-to-can basis. According to CR’s food safety experts, some cans of tuna have such high levels of mercury that it could impact the health of an unborn child if eaten by a person who is pregnant.
However, CR also found that canned tuna, especially light varieties, has relatively low average levels of mercury in general. The unpredictable levels of mercury found from can-to-can are still a concern for vulnerable populations, per CR.
