The largest study ever on farmed salmon, which are raised in captivity in the oceans, indicated that the fish contain a number of toxins and pesticides and may be unsafe to eat. The Pew-funded study recommended eating farmed salmon no more than once a month, but media coverage focused on the study's methodology, which used stringent EPA guidelines. The FDA deemed the levels safe, called the study flawed, and recommended the public not alter its eating habits.Most frequent messages: 1.
