Why are some animal treatments not registered?
Why are some animal treatments that look like pesticides not registered by the US Environmental Protection Agency?
Animal drugs are regulated by the FDA (US Food & Drug
Administration) under FFDCA (Federal Food, Drug & Cosmetic Act).
Animal drugs are products used to control bacteria, fungi, viruses and
other microorganisms on or in living animals, as well as any internal
parasites of living animals. Products used for control of external
invertebrate/insect parasites are considered pesticides and are
regulated by the EPA (US Environmental Protection Agency).
This information can be found at 40 CFR (Code of Federal Regulations) Part 152.5 (definition of pests) and Part 152.6(d) (substances excluded from regulation under FIFRA (Federal Insecticide, Fungicide & Rodenticide Act) - animal drugs).
