The purpose of this retrospective study was to analyse the etiology, frequency and outcome of toxicological cases recorded by the consultation service of the Swiss Toxicological Information Centre (STIC) hotline over a 10-year period, from 1997 to 2006. A detailed analysis of this database indicates that common human drugs not intended for use in animals, as well as pesticides and toxic plants represent the most prominent hazards involved in the reported cases of animal poisonings. The comparison with a previous survey from the years 1976 - 1985 revealed new toxic risks due to the accidental uptake of cannabis products, castor seeds or chocolate by dogs. In addition, there is a striking increase of serious poisonings with pyrethroids in cats. The follow-up reports delivered by veterinarians also reflect novel pharmacological and technological trends in the management of poisonings.
