Mercury Calculator

We don't cook fish for a long time because concerning the mercury contamination.

Here I found a good and useful mercury calculator, maybe a good reference for the future use.

I read an article saying that there are 4 types of fish that should be on the list to avoid due to mercury levels. These include: shark, king mackerel, swordfish and tilefish. And FDA has released guideline that no more than 12 oz of low mercury fish should be consumed weekly.
Ummm, they are good references too.
