An undercover investigation of fish from eight Los Angeles area seafood counters and ten sushi restaurants revealed alarming levels of mercury. Twenty three samples of swordfish, ahi tuna and salmon were tested for mercury levels and the results showed one in three samples registered well above the level of 1 part per million set by food safety officials at the Food and Drug Adminstration (FDA).
The results from the ten tuna sushi samples were equally disturbing. One in five tuna sushi samples were above the FDA’s mercury action level, with one sample registering twice the action level.
Eating fish is the number one source of mercury exposure in the United States.
