Raw safety data returned.","data":{"risk_level":"moderate","summary":"Flumethrin is a type II alpha-cyano pyrethroid used exclusively in veterinary products — most prominently as one of two active ingredients in the Seresto collar (imidacloprid + flumethrin; Elanco/Bayer) for flea and tick prevention in dogs and cats, as well as livestock ectoparasiticide dips (Bayticol), sprays, and pour-ons (Butox) for cattle, sheep, and poultry. Oral LD50 rat ~269 mg/kg; WHO Class II. Human exposure occurs through handling of treated animals, Seresto collar contact, and occupational livestock treatment. The sustained-release collar technology results in very low systemic absorption in target animals and negligible human dermal transfer under normal handling conditions."},"meta":{"synthesis_version":"n/a","timestamp":"2026-10-28T20:51:07.228Z"},"_notice":"ALETHEIA output is reference data, not professional advice.
