According to the report released Thursday, eating pangasius imported from Vietnam and China could have "serious long-term human health consequences."

The report cites "major hazards" associated with aquaculture fish, including pathogenic microorganisms, antimicrobial drug residues and environmental chemicals.

U.S. Sen. Blanche Lincoln, D-Ark., chairwoman of the Senate Agriculture Committee, joined the group, Food & Water Watch, and the Catfish Farmers of America, in unveiling the report in Washington, D.C.

Lincoln said she had been "loud and clear" on the U.S. Department of Agriculture's (USDA's) delay in implementing the catfish inspection rule, part of the 2008 Farm Bill, which shifted jurisdiction over catfish safety from the U.S.
