There are more problems for Buckeye Egg farms today. The company has been cited by federal inspectors for ignoring livestock-feeding rules designed to protect consumers from drug-contaminated eggs and mad-cow disease. The Columbus Dispatch is reporting today that the mega-farm has been ordered to change the way it feed chickens and administers production-enhancing drugs or face unspecified penalties. The U-S Food and Drug Administration says the mega-farm has been failing to carefully measure and monitor the medications it adds to chicken feed. Experts say violations such as those cited by the F-D-A raise the risk of exposing egg consumers to antibiotics unfit for human consumption, developing medication-resistant strains of salmonella and spreading mad-cow diseases. Buckeye Egg, which has a farm in Licking County, is one of the nation’s largest egg producers.
