"Residual antibiotics have been detected in Chilean salmon that have been exported to the United States, Canada and Europe, Dr. Cabello said.
He estimated that 70 to 300 times more antibiotics are used by salmon producers in Chile to produce a ton of salmon than in Norway. But no hard data exist to corroborate the estimates, he said, “because there is almost an underground market of antibiotics in Chile for salmon aquaculture.”
Researchers say that some antibiotics that are not allowed in American aquaculture, like flumequine and oxolinic acid, are legal in Chile and may increase antibiotic resistance for people. Last June the United States Food and Drug Adminstration blocked the sale of five types of Chinese seafood because of the use of fluoroquinolones and other additives.
But huge numbers of fish go uninspected. The F.D.A. inspected only 1.93 percent of all imported seafood in 2006, Food and Water Watch said, citing F.D.A. data."
