An outbreak of acute oxalate intoxication in a sheep flock was associated to Seidlitzia rosmarinus (Chenopodiaceae) with a mortality rate of about 19%. Affected sheep showed marked azotemia and hypocalcemia. Post-mortem findings included congestion and hemorrhage in visceral organs, ruminitis frequently associated with precipitation of birefringent calcium oxalate crystals, and acute nephrosis with numerous birefringent calcium oxalate crystals in renal tubules. This is the first report of oxalate poisoning due to ingestion of S. rosmarinus in sheep.
