Check out the databases listed here for more detailed information on the amounts of mercury found in various types of fish and shellfish sold at fish markets, grocery stores, and other commercial locations. Tables display the average (mean) as well as minimum and maximum mercury levels detected for each type of fish:
Shows results of the agency's tests for mercury in fish from 1990 through 2010, which our food safety experts analyzed as the basis for making our recommendations. FDA data is commonly used as a basis for mercury risk assessment and exposure estimates by scientific researchers and some state government officials.
This resource combines the FDA’s results with data from other federal and state reports, along with mercury test results from studies published in scientific journals. The average (mean), minimum and maximum mercury levels displayed for each type of fish are based on aggregated test results from approximately 300 different sources, and the table includes some species of fish not found in the FDA’s data.
