The use of cytotoxic drugs to treat neoplastic conditions is increasing in veterinary practices. Many agents have the potential to be genotoxic and evidence of exposure to cytotoxic drugs has been found in healthcare workers handling these pharmaceuticals. To date, limited contamination evaluations have been performed in veterinary practices. Evaluation for carboplatin contamination was performed at a veterinary teaching hospital involving twelve areas in the dispensary and treatment room. Detectable levels of platinum were found on the surface of the biological safety cabinet where drugs are transferred from vial to administration device. Results indicate contamination did occur and care must be taken during all phases of cytotoxic drug preparation and administration; precautionary procedures must be in place to limit the spread of surface contamination and personnel exposure.
