A new study claims Canadian salmon has low-levels of contaminants, including mercury. WebMD is on it:
Total mercury levels in the wild salmon tested were three times higher than in farmed, but total mercury intake from both types of fish was found to be lower than from many other foods.And according to Dr. Fuhrman, in addition to salmon, fishes like flounder, sole, tilapia, and trout are also safer choices.
The study was funded by the Canadian fishing industry, which supplies much of the farmed salmon eaten in the United States.
In recent years, concerns have been raised about the safety of farmed salmon vs. wild, and there have also been suggestions that Canadian and other Atlantic-farmed salmon contains more contaminants than farm-raised fish from other areas, such as Chile. The newly published study was conducted in an attempt to address these concerns.
Researchers measured mercury levels as well as levels of 18 other trace metals in commercial salmon feed and farmed and wild salmon from British Columbia fisheries and waters.
