Description:

Fipronil is a phenylpyrazole insecticide used to control fleas, ticks, ants, termites, and other insect pests. It is found in some veterinary flea and tick treatments and residential pest control products and has also been used in agricultural applications. Potential exposure may occur through handling treated pets, contact with treated surfaces, or residues in food and the environment.

Health concerns:

Cancer

Known or suspected to increase cancer risk in humans.

Organ System Toxicity

May cause organ damage and disease.

Ecotoxicity

May be toxic to ecosystems and wildlife.

HOW MILLION MARKER SCORES CHEMICALS

Million Marker's Ingredient Hazard Scoring uses multiple chemical databases and a science-backed scoring system to compute hazard scores for thousands of chemicals found in consumer products and listed on ingredient labels.

We identified key chemicals based on a database compiling dozens of authoritative sources, screening tools, and QSAR models.

Hazard scores within 11 different health categories (carcinogens, endocrine disruptors, reproductive toxicants, developmental toxicants, genotoxicity, neurotoxicity, organ system toxicity, immunotoxicity, respiratory toxicity, skin/eye/respiratory irritants, and ecotoxicity).

They are weighted based on several factors, including strength of evidence for adverse impacts in humans, severity, and potential contamination.
