All fish contain some mercury, but you should avoid eating too much high-mercury fish. Here's the limit on how much adults should consume: Pregnant and nursing women should consume one-fourth that much. Don't know how many "parts per million" are in your favorite kind of fish? See the chart to the right for types of fish and their mercury concentration.

Mercury occurs naturally in the environment and is also released into the air and water through industrial pollution from pulp and paper processing, mining operations, coal-burning plants and garbage incinerators. Mercury in fresh and marine waters is converted by bacteria into methylmercury, which is easily absorbed by animals as they feed and binds to fish protein. Methylmercury accumulates in fish tissue and becomes concentrated in fish high on the food chain. See similar questions...

Health Canada has established a guideline level of 0.5 parts per million (ppm) for mercury in most commercial fish. This guideline is enforced by the Canadian Food Inspection Agency (CFIA). It was first set in the 1970's and, based on a recent re-evaluation, is still considered appropriate to ensure that the health of Canadians is protected from the toxic effects of methyl mercury.

Fish are an excellent source of high-quality protein, are low in saturated fat, and are one of the healthiest food choices you can make. However, certain types of fish should be eaten in moderation, because of trace amounts of mercury. The Canadian Food Inspection Agency (CFIA) advises consumers to limit their consumption of swordfish, shark or fresh and frozen tuna to one meal per week. Note that this does not apply to canned tuna. See similar questions...

It happens through the food chain. In the bottom sediments of rivers, lakes, and oceans, mercury undergoes methylation, a process carried out by bacteria in certain conditions. Small fish eat small snails, crawfish and insects that have eaten even smaller things containing methylmercury. Then larger predator fish, like bass, eat the smaller fish. Since bass are at the top of the freshwater food chain, they can build up methylmercury. See similar questions...

Nearly all fishes and shellfish contain traces of methylmercury. However, older predatory fish have the highest levels of methylmercury because they have had more time to accumulate it. Fishes such as swordfish, shark, king mackerel, tuna and tilefish pose the greatest risk. Fisheries marked with the diamond warning symbol on our card may contain one or more species that poses a mercury-related health risk with regular consumption. See similar questions...

Mercury is a heavy metal that occurs naturally in the environment and can also be released into the air through industrial pollution. Mercury falls from the air into the water and is converted into a toxic form called methylmercury. Fish absorb the methylmercury as they feed in these waters. High levels of methylmercury can accumulate in larger predatory fish because they eat large numbers of smaller fish.

Mercury is a naturally occurring metal which has several forms. The metallic mercury is a shiny, silver-white, odorless liquid. If heated, it is a colorless, odorless gas. Mercury combines with other elements, such as chlorine, sulfur, or oxygen, to form inorganic mercury compounds or "salts," which are usually white powders or crystals. Mercury also combines with carbon to make organic mercury compounds. See similar questions...

Hard to say, it's just this tradition. There's this band I'm in (The Electric Fish), it's a reference to one of the first X programs I wrote (xfish), there are 15 fish-objects (stuffed, wooden, etc) in the room where I'm typing this, etc. And I don't even own any real fish.

The problem of mercury in fish is not unique to Louisiana, it is a global problem that many other states and countries are working to address. Mercury in fish is not new, either. In fact, scientists believe the levels of mercury found in our fish today are probably similar to those of the past 40 years. What is new is that we know more about mercury's harmful effects now than we did 40 years ago, and we can better measure mercury in fish. See similar questions...

While it's true that some species of fish can contain an organic form of mercury called methylmercury, it's generally not enough to be a hazard to most consumers. For safety's sake, in 2004 the FDA and EPA did advise pregnant and nursing women, women who might become pregnant, and young children to eat no more than 12 ounces a week (the equivalent of 2 average meals) of shrimp, salmon, pollock, catfish and canned light tuna, and to avoid shark, swordfish, tilefish and king mackerel entirely.

The Environmental Protection Agency, EPA has collected fish and sent them to a laboratory for analysis. This analysis is costly and takes time. (If you wanted to analyze the fish you bought, by the time you got the results back your fish would be too old to eat). RI adopted the EPA Ambient Water Quality Criteria of 0.3 parts per million (ppm). Fish found to have this amount of mercury or less in them are deemed "safe". See similar questions...
