According to the National Organic Program (NOP) final rule (United States Department of Agriculture [USDA], 2000), parasiticides may only be used on:
- Breeder stock, when used prior to the last third of gestation, but not during lactation, for progeny that are to be sold, labeled, or represented as organically produced; and,
- Dairy stock, when used a minimum of 90 days prior to the production of milk or milk products that are to be sold, labeled, or represented as organic.
At the present time, ivermectin is the only parasiticide on the National List, and, therefore allowed with the restrictions noted above.
