The ecological assessment evaluates how the product moves through and breaks down in the environment and its effects on non-target birds, fish, invertebrates, mammals, and plants.\n\nTo keep registered products current, `EPA reviews active ingredients in flea and tick product at least every 15 years` — `This process, known as registration review` — which may trigger label changes to address identified risks.\n\nOversight between EPA and FDA for topically administered flea/tick products is split by route of exposure: `Since the mid-1970s, EPA and the Food and Drug Administration (FDA) have determined oversight for products topically administered to animals` based on whether the chemical is `systemically absorbed into the bloodstream (FDA oversight) or remains on the skin (EPA oversight)`. EPA now recognizes that many EPA-regulated topical products are absorbed systemically, raising different concerns than originally anticipated.\n\nIn response, `In February 2023, EPA and FDA jointly released a whitepaper` proposing an updated approach, including `transferring oversight of flea and tick pet products from EPA to FDA`.\n\nRelated: `epa_pet_collar_products` (collar-specific evaluation and data collection) and `epa_pet_adverse_reaction` (what owners should do after an adverse event).\n\nSource: `pdf-parsed/epa/epas-regulation-flea-and-tick-products.txt` (US EPA, landed 2026-08-11).\n## Claims (verified C1 substrings of source_file)\n- `EPA is responsible for ensuring that all pesticides, including flea and tick products, sold in the United States do not cause unreasonable adverse effects when they are used according to label directions.`\n- `EPA conducts a human health risk assessment and an ecological risk assessment`\n- `EPA also reviews companion animal safety data`\n- `EPA reviews active ingredients in flea and tick product at least every 15 years`\n- `This process, known as registration review`\n- `Since the mid-1970s, EPA and the Food and Drug Administration (FDA) have determined oversight for products topically administered to animals`\n- `systemically absorbed into the bloodstream (FDA oversight) or remains on the skin (EPA oversight)`\n- `In February 2023, EPA and FDA jointly released a whitepaper`\n- `transferring oversight of flea and tick pet products from EPA to FDA`\n","sources":["US EPA pet pesticide pages — EPA's Regulation of Flea and Tick Products (retrieved 2026-08-11)"],"source":{"authority":"US EPA pet pesticide pages","title":"EPA's Regulation of Flea and Tick Products","url":"https://www.epa.gov/pets/epas-regulation-flea-and-tick-products","retrieved":"2026-08-11","ref":"","doc_type":"official PDF","source_document":"US EPA — EPA's Regulation of Flea and Tick Products","verification_file":"pdf-parsed/epa/epas-regulation-flea-and-tick-products.txt"},"source_document":"US EPA — EPA's Regulation of Flea and Tick Products","source_file":"pdf-parsed/epa/epas-regulation-flea-and-tick-products.txt","trust":{"authority_tier":"ungraded","fidelity":"verbatim","license":"public_domain","display_grade":"pending"},"tokens_estimated":280,"generated_at":null,"tip":"Use /api/v1/topics to discover more topics. /api/v1/nutrient for precise single-point queries. /api/v1/cross_compare for 2-3 standard comparisons."}
