Lists of Safe and Unsafe Seafood and Fish and All About Mercury Contamination

Fish - Seafood - Mercury Contamination

Fish and Mercury Contamination – A General Rule of Thumb

The larger the particular seafood species and the longer that species normally lives, the higher that species' mercury content and levels.

This is the result of two factors:
  • Larger fish consume more food, and therefor consume more mercury.
  • Longer-living species consume more food than shorter-lived species, thus again consuming more mercury. 

Basic Ranking of Fish and Seafood Species And Their Mercury Content Levels

List of Fish and Seafood Having the Highest Mercury Concentrations

The following list of fish species having the worst mercury content contamination. The mercury levels are so high, the EPA flatly states that pregnant women (and women trying to become pregnant) and young children should not eat them at all.
  • King Mackerel
  • Tilefish
  • Swordfish
  • Shark 

List of Seafood and Fish That Are Lower in Mercury Content
