Lab tests on imported Chinese catfish samples pulled from Mississippi grocery store shelves have found seven additional positive hits for illegal antibiotics.

According to a Mississippi Department of Agriculture and Commerce press release, as of May 8, 16 samples had been collected for testing with 11 of those samples testing positive for the banned antibiotics ciprofloxacin and enrofloxacin.

A “stop sale order” was issued to the grocery stores carrying these items when laboratory results were confirmed. The latest positive tests came from imported Chinese catfish being sold in the following Mississippi grocery stores: Mac’s Meat Market in Starkville, D&T Supermarket in Clarksdale, Save-A-Lot in Gulfport and Clarksdale, Sunflower Food Store in Poplarville, Southern Family Market in Meridian, and Walden’s Big Star in Booneville.

On May 1, the Mississippi Department of Agriculture issued a “stop sale order” after testing confirmed the presence of the banned antibiotics belonging to the fluoroquinolone drug family.
