The Food and Drug Administration (FDA) announced a broader import control of all farm-raised catfish, basa, shrimp, dace (related to carp) and eel from China. FDA will start to detain these products at the border until the shipments are proven to be free of residues from drugs that are not approved in the United States for use in farm-raised aquatic animals.
Were taking this strong step because of current and continuing evidence that certain Chinese aquaculture products imported into the United States contain illegal substances that are not permitted in seafood sold in the U.S., said Dr. David Acheson, FDAs assistant commissioner for food protection. We will accept entries of these products from Chinese firms that demonstrate compliance with our requirements and safety standards.
During targeted sampling from October 2006 through May 2007, FDA repeatedly found that farm-raised seafood imported from China were contaminated with antimicrobial agents that are not approved for this use in the United States.
The contaminants were the antimicrobials nitrofuran, malachite green, gentian violet and fluoroquinolone. Nitrofuran, malachite green and gentian violet have been shown to be carcinogenic with long-term exposure in lab animals. The use of fluoroquinolones in food animals may increase antibiotic resistance to this critically important class of antibiotics.
None of these substances is approved for use in farm-raised seafood in the U.S., and the use of nitrofurans and malachite green in aquaculture is also prohibited by Chinese authorities. Chinese officials have acknowledged that fluoroquinolones are used in Chinese aquaculture and are permitted for use in China.
The levels of the drug residues that have been found in seafood are very low, most often at or near the minimum level of detection. FDA is not seeking recall of products already in U.S. commerce and is not advising consumers to destroy or return imported farm-raised seafood they may already have in their homes. FDA is concerned about long term exposure as well as the possible development of antibiotic resistance.
FDA may allow the entry into the United States and subsequent distribution into the marketplace of individual shipments of the Chinese farm-raised seafood products if the company provides documentation to confirm the products are free of residues of these drugs.
