United States Department of Agriculture, Food Safety and Inspection Service (USDA/FSIS) analysis of tissue samples collected from a bob veal calf identified the presence of neomycin at 8.42 parts per million (ppm) in the kidney tissue of the animal. The FDA has established a tolerance of 7.2 ppm neomycin in cattle kidney. Neomycin is an antibiotic used to kill bacteria in the intestinal tract.
The investigation also found that Mellot held animals under conditions that are so inadequate that medicated animals bearing potentially harmful drug residues were likely to enter the food supply, and that Mellot failed to maintain treatment records on medicated animals.
