I was mainly quoting saltwater fish for mercury content. I heard about Pacific salmon and tuna. There is a old man that eats the fish out of the James here. He just puts them into a spring fed holding pond for a couple of weeks and he swears the fish taste better after that. As aid he has been eating them for over 50 years that way.So in GA the EPD gives 4 different guidelines,
1) No restrictions
2) 1 meal per week
3) 1 meal per month
4) Do not eat
Lets just say the fish / body of water is in Catagory #3 One meal per month. If you eat one meal per month 12 months out of the year. For the next 35 years. You would have no statistically higher risk of cancer. (Unless you are eating it off of a Dupont Teflon Pan from the 90's)
I am not trying to argue or change anyones mind. I definitely won't eat those big stripers or catfish. But I have eaten 100 pound wahoo that you could damn near see the mercury dripping off of.
If you eat fish, even store-bought fish you should at least read thru the guidelines. It is a pretty interesting read.
Fish Consumption Guidelines
Fishing is a popular pastime in Georgia. Not only does fishing give people an excuse to get away from the hustle and bustle of daily life, but it can also put a healthy, satisfying meal on the table.epd.georgia.gov
