A patient fatality following the ingestion of a small amount of chlorfenapyr

Chlorfenapyr has been used worldwide for agricultural pest control since 1995. Despite its widespread use, acute human poisoning data are insufficient; only a small number of fatalities from chlorfenapyr poisoning have been reported. The signs and symptoms of chlorfenapyr toxicity include nausea, vomiting, fever, rhabdomyolysis, among others. In addition, central nervous system effects in association with delayed toxicity have also been observed. Here, we detail a fatality resulting from delayed chlorfenapyr toxicity following the ingestion of a small amount of pesticide.
