Actual numbers from the Science salmon study:
The team took a closer look at PCBs and two other persistent pesticides called dieldrin and toxaphene, all of which have been correlated with risk of liver and other cancers. The researchers used EPA guidelines to calculate the maximum amount of salmon that can be eaten before boosting cancer risk by at least 1 case in 100,000. For the most contaminated fish--from farms in Scotland and the Faroe Islands--the limit came to 55 grams of salmon (uncooked weight) every month, or a quarter of a serving. One half-serving a month of farmed salmon from Canada or Maine adds no significant risk, they say; and double that is acceptable for fish from Chile or the U.S. state of Washington. Some types of wild salmon from Alaska or British Columbia are safe to eat eight times a month.

Although no U.S. government agency has said how much fish one should eat, the American Heart Association recommends 168 to 336 grams per week. Consumption of the omega-3 fatty acids found in fatty fish reduces the risk of sudden cardiac death after a heart attack. For people with cardiovascular disease, that benefit outweighs any added cancer risk, Carpenter says.

Sorry, yawn. Perhaps you've also noticed that farmed salmon tastes like shit? [Post article]
