Sources of exposure:

Medications
Pesticides

Prescription anticoagulant medications, historical and some currently authorized rodenticides, pest-control baits, and accidental contact with rodent-control products

Description:

Warfarin is a synthetic anticoagulant used as a prescription medication to prevent or treat blood clots. It has also been used as a rodenticide because it interferes with vitamin K-dependent blood clotting. Exposure may occur through prescribed medication or contact with rodent-control products containing warfarin.

Health concerns:

Reproductive Toxicity

May alter hormone function and harm reproduction.

Developmental Toxicity

May impact fetal development and birth outcomes.

Genotoxicity

May cause mutations or damage DNA in cells.

Organ System Toxicity

May cause organ damage and disease.

Irritant

May cause skin, eye, or respiratory irritation.

Ecotoxicity

May be toxic to ecosystems and wildlife.

Banned/restricted lists:

  • California Proposition 65 - OEHHA - developmental

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.
