The US Food and Drug Administration announced that Phibro Animal Health Corporation withdrew its approved New Animal Drug Application (NADA) for antibiotic-containing feeds from the market voluntarily.

The company withdraw approval of NADA 098-371 for the use of nicarbazin, penicillin and roxarsone in three-way, combination drug Type C medicated feeds for broiler chickens, and NADA 098-374 for use of nicarbazin and penicillin in two-way, combination drug Type C medicated feeds for broiler chickens. These drugs have been approved for use in animal feed for over 40 years.

Beyond the fact that these products are no longer being manufactured or marketed, the decision to remove these antibiotic-containing feeds from the market for production purposes supports FDA's voluntary strategy for judicious use of antibiotics in food-producing animals.
