Pesticide poisoning in domestic animals and livestock in Austria: A 6 years retrospective study

A 6 years retrospective study of pesticide poisonings in domestic animals and livestock from 1999 to 2004 submitted to the Institute for Medical Chemistry, University of Veterinary Medicine, Vienna in Austria was compiled and analysed. Totally 380 pesticide analysis requests were referred by veterinary practitioners, from the Institute for Pathology of the above university, by regional and central governments as well as local police departments and district administrations, animal protectionist groups, public health authorities and private clients. Among the total number of suspected samples for pesticides, 175 (46.1%) cases were found positive to contain pesticides of various kinds. Among the pesticides found, carbamate insecticides were most prominent, representing 50.3% of the total positive cases. These compounds were followed by rodenticides–anticoagulants with 18.9% of the positive results, by organophosphate insecticides 5.1%, and by the rodenticides–nonanticoagulant 3.4%, the other 22.3% included molluscicides, herbicides, etc. In totally 225 animals, 123 animals were found positive for pesticide intoxication, among them 47.2% were dogs, 34.1% were cats 9.8% of other species and 8.9% of unspecified animal samples. The pesticides were characterized by HPLC-techniques using commercially available standards. The aim of this Austrian survey was to determine the incidence and frequency of confirmed pesticide intoxications in animals in Austria and to emphasize its relevance in veterinary practice for livestock and domestic animals.
