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.

No: Fish with very high potential mercury levels: shark, swordfish, marlin, king mackerel, big eye & ahi tuna, orange roughy & tilefish. Limit intake of yellow fin & white albacore tuna, spanish & gulf maceral, group, bluefish & chilean sea bass. For healthier mercury levels try: crabs, crawdaddies, haddock, flounder, salmon, shrimp, oysters, anchovies, herring, mullet, sole, clams & freshwater trout.

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.

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.

Depends.: Mercury from eating fish can be a problem, but there are ways to keep it to a minmum or safe level. Certain groups should be more careful, including pregnant women, young children/ infants, and breastfeeding mothers. Google "fish, mercury" and you will get several websites that have downloadable charts that tell which fish are safer for both mercury and pcbs (another toxin in some fish).
