Tainted Seafood

Only about 2 percent of imported seafood is inspected, and only 0.1 percent is tested for banned drug residues, according to the U.S. Government Accountability Office (GAO), the investigative arm of Congress. That's especially alarming because 80 percent of the seafood in America is imported, according to the agency.

The FDA says it can't say for sure how many of the samples pass or fail.

But a News21 analysis of FDA import-refusal data reveals an unappetizing portrait. In more than half of cases when seafood is rejected, the fish has been deemed filthy, meaning it was spoiled or contained physical abnormalities, or it was contaminated with a foodborne pathogen. About 20 percent of those cases involved salmonella. People who eat seafood that is raw or undercooked are especially vulnerable to bacteria that may be lurking.
