Phibro voluntarily requests withdraw of medicated feed products

Phibro Animal Health voluntarily requests that FDA withdraw approval of two medicated feed combinations.

The U.S. Food & Drug Administration announced Aug. 22 that Phibro Animal Health Corp. 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 more than 40 years, FDA said.

Although Phibro Animal Health withdrew its approved NADAs voluntarily because these products were 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, the agency said.
