People who eat commercially-caught fish in the United States are at risk for poisoning. It is almost certain that such cases occur in less than one percent of the population. They can be fatal, but they do happen. The most common cause of mercury poisoning is ingestion of fish contaminated with mercury. Mercury is a naturally-occurring element that occurs naturally in many foods, including fish.
It is also found in soil and water, but it is most commonly found as a by-product of coal-burning power plants and other industrial processes. Because of its toxicity to humans, mercury has been banned from use in a number of consumer products, such as dental amalgam and dental fillings, as well as in some pharmaceuticals and medical devices.
(FDA) continues to allow the use of some mercury-containing products as long as they are labeled as containing no more than 0.5 parts per million (ppm), which is the limit set by the Environmental Protection Agency (EPA) for mercury in drinking water. This limit is based on the assumption that most people ingesting these products do not exceed this level.
How long does it take to get mercury poisoning from fish?
It can take weeks or months to be poisoned. If you have a chemical spill with mercury, you might experience symptoms more quickly. Mercury poisoning can be diagnosed by testing your blood and urine levels. It is possible to collect urine over a 24 hour period and send it to a laboratory for testing.
Should I worry about mercury in fish?
Most men do not need to worry about mercury exposure from eating fish. You can reduce your exposure to mercury by eating a diet rich in omega-3 fatty acids, such as fish, flaxseed, walnuts, and sesame seeds.
Also, you can take a multivitamin containing vitamin A, vitamin D, calcium, magnesium, zinc, selenium, niacin, riboflavin (B2), and vitamin B12. These supplements can also help prevent the buildup of mercury in your body. For more information, visit the U.S. Environmental Protection Agency’s website at www.epa.gov/mercury.

Which fish has most mercury?
Larger and longer-lived fish tend to have more mercury than smaller fish. These include shark, swordfish, fresh tuna, marlin, king mackerel, tilefish from the Gulf of Mexico, and northern pike. Smaller fish with small amounts of mercury in their tissues are more likely to be eaten by larger fish.
