Fatal poisoning of a Griffon vulture (Gyps fulvus) with methomyl

Abstract

A young Griffon vulture died with signs of convulsion, vomiting, tremor, seizures propulsions and lack of co-ordination. Toxicological analysis of the stomach content revealed the presence of methomyl (9.3 mg/kg), methomyloxime (6.7 mg/kg) and deltamethrin (6.1 mg/kg). Concentrations of methomyl and its intermediate methomyloxime, combined with results of other analysis, indicate methomyl as the cause of death of this bird.
