Raw safety data returned.","data":{"risk_level":"moderate","summary":"Chlorophacinone (Rozol, Caid, Topitox) is a first-generation anticoagulant rodenticide (FGAR) of the indandione class; oral LD50 rat ~20 mg/kg — less acutely toxic than most other anticoagulant rodenticides. Requires multiple feedings for rodent control. Half-life in humans shorter than SGARs. Used in prairie dog, ground squirrel, and vole control programs in agricultural settings; also used in Western US for black-tailed prairie dog management as part of plague-control programs (reducing plague reservoir host density). Occupational exposure in agricultural hand-loading of bait is the highest human exposure scenario. Treatment: vitamin K1 for 2–4 weeks; response typically good. Human poisoning cases are rare; the primary concern is occupational exposure during mixing and bait station filling in large-scale agricultural programs."},"meta":{"synthesis_version":"n/a","timestamp":"2026-05-01T19:40:09.725Z"}}
