Three Sumatran tigers (Panthera tigris sumatrae) at the Heidelberg Zoo in Germany presented with severe neurologic signs. Physical examination and diagnostic tests did not reveal a definitive diagnosis. Two days after initial presenting signs, all of the animals appeared clinically normal. An investigation into this outbreak revealed that all animals received horse meat on the evening before the incident. A toxicologic examination was initiated and serum analysis of the affected female tiger cub and the horse meat revealed contamination with pentobarbital.
