According to the National Organic Program (NOP) final rule (United States Department of Agriculture [USDA], 2000), the use of parasiticides is prohbitied for all organic slaughter stock. When preventative treatments do not prevent infestation, parasiticides may be used for emergency treatment of:
At the present time, Ivermectin (CAS# 70288-86-7); Fenbendazole (CAS# 43210-67-9); and Moxidectin (CAS# 113507-06-5) are the only parasiticides on the National List and, therefore, allowed with the restrictions noted above. Fenbendazole can only be used by or on the lawful written order of a licensed veterinarian. Moxidectin can only be used for control of internal parasites.
