  • This is especially dangerous for pregnant and breastfeeding women because fetuses and newborns are very sensitive to mercury.
  • Shrimp and prawn are important types of seafood that are consumed worldwide.

Since fish is low in saturated fat and high in heart-friendly omega-3 fatty acids, eating it during pregnancy is very important. But seafood is the only significant source of mercury in our food, and some fish have levels of mercury so high that it may be harmful to a developing baby. No more than two helpings a week of low-mercury fish are what the experts recommend.

Heavy metals like mercury and lead are toxic to the brain and nervous system. Though acute poisoning is rare, small amounts of organic mercury compounds like methylmercury found in some seafood may have subtle effects on fetal and childhood development.

Methylmercury easily passes through the placenta to the fetus and deposits in fetal tissues. The toxin also passes through breast milk, but not as easily as through the placenta. No, it just means you need to choose your fish more carefully. In general, the larger and longer-lived the species, the more mercury the fish will accumulate by the time it's caught and eaten. Methylmercury binds to the muscles of fish, so cooking the fish will not get rid of it.

Fish and shellfish are important sources of lean protein and omega-3 fatty acids, and you don't have to give them up entirely. According to the U. Food and Drug Administration FDA , it's safe for pregnant and nursing women to eat up to 12 ounces of low-mercury seafood like salmon per week, OR up to 6 ounces of albacore white tuna per week.

The FDA also lists four types of high-mercury fish to avoid entirely while pregnant: shark, swordfish, king mackerel, and tilefish from the Gulf of Mexico. In general, smaller fish of a given species are lower in mercury. Most types of shellfish also have low levels of mercury, although North American lobster is an exception.

FDA guidelines state that it's safe for women who are pregnant or nursing or thinking of becoming pregnant soon to eat up to 12 ounces of seafood low in mercury, OR up to 6 ounces of albacore white or tombo tuna per week.

Albacore tuna is sold as steaks and canned solid and chunk and is the only kind that can be sold as "white" tuna. The reason that the FDA singled out albacore is because it tends to have higher levels of mercury than other tuna varieties commonly eaten in the U. However, some experts feel that even 6 ounces of albacore a week is too much for pregnant women; to be on the safe side, some advise pregnant women and young children to avoid albacore, bluefin, and other large tuna species altogether.

Other canned tuna -- sold as "light" tuna solid and chunk -- can be from different species of tuna. In general canned chunks are made from smaller fish and generally have half to one-third the level of mercury found in albacore most canned tuna averages 0.

Keep in mind that if you eat any tuna as steaks or sushi, it's likely to be from larger fish, so you should apply the albacore guidelines to be on the safe side. If you stick to safe choices, you can have your fish and eat it, too.

The mercury found in fish is methylmercury. First, mercury is released into the air and then settles onto the land and into the water. Bacteria and other microorganisms convert the mercury into methylmercury. Then, fish and shellfish in the water begin to absorb it. Fish that eat other fish and who live longer have higher levels of methylmercury.

Methylmercury is toxic to the central nervous system—the brain and spinal cord. It causes irreversible damage. The brains of unborn babies and infants are especially susceptible. How much damage is done depends on how much you are exposed to the chemical. The effects of methylmercury poisoning include cerebral palsy, blindness, deafness, impaired mental functioning, impaired lung function, growth problems, and having a small head.

Large fish have more mercury for the simple reason that big fish usually live longer. They have more time to build up higher levels of mercury in their bodies.

These include shark, swordfish, fresh tuna , marlin, king mackerel, tilefish from the Gulf of Mexico, and northern pike 5.

Larger fish tend to eat many smaller fish, which contain small amounts of mercury. This process is known as bioaccumulation 6. Mercury levels in fish are measured as parts per million ppm. Here are the average levels in different types of fish and seafood, from highest to lowest 5 :. Eating fish and shellfish is a major source of mercury exposure in humans and animals.

Exposure — even in small amounts — can cause serious health problems 7 , 8. However, sea plants like algae absorb it. Fish then eat the algae, absorbing and retaining its mercury. Larger, predatory fish then accumulate higher levels from eating smaller fish 9 , In fact, larger, predatory fish may contain mercury concentrations up to 10 times higher than the fish they consume.

This process is called biomagnification One U. What's more, many studies have determined that people who regularly eat larger fish — such as pike and perch — have higher levels of mercury 14 , Exposure to mercury can cause serious health problems In both humans and animals, higher levels of mercury are associated with brain problems.
