Mercury...: It poisonous to the human body. Mercury levels in various foods will accumulate in the body and can cause harm. I don't know about a conspiracy but everything political seems to have some other motivations.

Can be an issue: Definitely more of an issue if pregnant or small child (developing nervous system). Little fish: little mercury. Big fish eat little fish and thus accumulate it. Not an issue for farmed fish (other issues for that). Eat small fish like sardines, herring, mackeral, salmon. Chunk light tuna is made from smaller fish than albacore so less mercury than solid white generally if you are eating canned.

Politics involved: Nobody questions that methylmercury accumulates in the food chain and that high doses it's neurotoxic, especially to the unborn child. Since nobody really has a clue about how this operates at very low doses, and there's not a shred of evidence of an effect on any population outside of two incredibly polluted sites, the EPA's required "recommendation" was something folks would accept easily.

You may enjoy reading about a screwball RIGHT-wing claim a few years back, involving the new spirally light bulbs being a dangerous source of mercury for consumers. This was promoted by the major far-right news organization.

Mercury in fish: Some fish, however, contain high amounts of mercury -- enough to damage a fetus or newborn. That is why pregnant and nursing mothers must be very careful about the amounts and types of fish they eat. Young children should also avoid eating fish high in mercury. According to the fda, pregnant women and small children (under 6) should not eat more than 2 servings of fish each week.

Can't remove mercury: Mercury increases throughout the food chain and is in largest concentrations in carnivorous fish. ('bioaccumulation') the mercury is in the flesh of the fish and cannot be removed through any process. It is best to avoid consumption of certain species known to have high levels of mercury. See http://water.Epa.Gov/scitech/swguidance/fishshellfish/outreach/advice_index.Cfm for more details.

Why is mercury in fish on the rise?

Likely pollutants.: Because of the chemical wastes dumped into rivers and lakes, etc. For many decades, there is more mercury in fish. Also, there are many more fishing vessels catching more fish in the world, so there is more exposure to mercury. Still anotyer reason is due to fish at the top of the food chain eating others and concentrating mercury in them.
