FDA Announces Phibro Animal Health Requests Voluntary Withdraw of Application for Medicated Poultry Feed

August 22, 2013

The U.S. Food and Drug Administration is announcing that Phibro Animal Health Corporation has requested that FDA withdraw approval of New Animal Drug Application (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.

Although Phibro Animal Health Corporation withdrew its approved NADA voluntarily because 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.
