Ron Kendall, director of The Institute of Environmental and HumanHealth (TIEHH) at Texas Tech, said researchers tested only themuscle tissues consumed by people. When concluded, they found thatabout 10 percent of the 30 samples tested contained evidence ofthree antibiotics. Though the sample sizes were small, he said finding antibioticresidues at all is cause for concern. Todd Anderson, a professor ofenvironmental toxicology, and instrument manager QingSong Caiconducted 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. Bothsamples were 28 and 29 times higher than the amount allowed by theU.S. Food and Drug Administration (FDA). The limit is 1 part perbillion. "Finding this particular antibiotic is of great interest,especially considering someone could have been eating an item thatwould have been banned," Kendall said. "Nitrofuranzone isa genotoxic substance. It can affect the DNA of cells and result ingenetic toxicity that can possibly result in cancer. You don't wantto ingest it. That's why the FDA has adopted a zero tolerancestance with it." The antibiotic chloramphenicol showed up in one sample at 150 timesthe current FDA required detection limits on prohibitedantimicrobial agents in seafood. Trace amounts of enrofloxacinshowed up in a sample purchased from a store in Washington, D.C. "With chloramphenicol, 45 parts per billion is considerablyhigher than the .3 parts per billion," Kendall said."It's a very powerful, broad spectrum antibiotic. There is areason why the U.S. FDA and other countries have set a very lowtolerance for this product. You shouldn't be consuming this." ABC contacted TIEHH to test the shrimp about a year after the U.S.General Accounting Office (GAO) raised serious questions about thesafety of imported seafood. In their 51-page report, they citedthat half of the seafood imported into the U.S. comes from fishfarms, and that these animals, when grown in confined areas, mayrequire antibiotics to treat infections. The GAO questioned the FDA's oversight program to check forunapproved drug residues in imported seafood samples and called itlimited, especially when compared to programs in the EuropeanUnion. Samples were purchased from grocery stores in New York, Washington,D.C., Atlanta and Los Angeles. "These findings were pretty surprising to me," Kendallsaid. "Considering someone may walk in to a grocery store tobuy shrimp to eat, I think that's worth further investigation, andmore extensive testing should be done. This was a grab-bagsampling, and we reported what we saw. I don't know yet if it's agreater problem or a lesser problem, but it should be looked intoat this point.".
