Mercury from eating too much fish?

I hear there's an upper limit to the amount of fish you should eat every day, particularly fish from the sea due to low levels of mercury inside them. Would it be safe to eat fish, say, every other day?

Consider that the Japanese consume a lot of sea fish today. They live longer than Americans and don't seem to be suffering from mental defects from mercury poisoning.

All fish cotain varying amounts of mercury-no level is safe, only less damage is done.

In March 2004, FDA and EPA revised its advisories on mercury in fish. Here is a summary:

Target Women who may become pregnant, pregnant women, nursing mothers, and young children to avoid some types of fish and eat fish and shellfish that are lower in mercury

Avoid Fish with High levels of Mercury Shark, Swordfish, King Mackerel, or Tilefish

12 oz. (~2 meals) of Low-Mercury Fish per week shrimp, crab, cod, clams, scallops, canned light tuna, canned salmon, pollock, and catfish etc.
Note: Albacore "White" tuna contains more mercury. Limit 6 oz (~1 meal) of albacore tuna per week.

For a complete list of fish and recommended portion, go to National Resources Defense Council

A person would be wise to NOT eat fish more than twice a week.Visit naturescorner.com, my website.

river and lake fish. Atlantic or Pacific fish aren't nowhere near as prone to high levels of mercury.

I would be worried more about the mercury in vaccinations such as the flu shot more than in fish.
