After testing farm-raised shrimp samples of international origin researchers at Texas Tech University found evidence of antibiotics -- one a suspected human carcinogen -- in seafood imported into the United States and purchased from grocery store shelves.

Ron Kendall, director of The Institute of Environmental and Human Health (TIEHH) at Texas Tech, said researchers tested only the muscle tissues consumed by people. When concluded, they found that about 10 percent of the 30 samples tested contained evidence of three antibiotics.

Though the sample sizes were small, he said finding antibiotic residues at all is cause for concern. Todd Anderson, a professor of environmental toxicology, and instrument manager QingSong Cai conducted the shrimp analyses.

In the study, researchers discovered the antibiotic nitrofuranzone, a probable carcinogen, in two of the samples purchased in New York -- one from a farm in India and the other from Thailand. Both samples were 28 and 29 times higher than the amount allowed by the U.S. Food and Drug Administration (FDA). The limit is 1 part per billion.

"Finding this particular antibiotic is of great interest, especially considering someone could have been eating an item that would have been banned," Kendall said. "Nitrofuranzone is a
