Botulism is a poisoning caused by the ingestion of toxins produced by Clostridium botulinum, that infects mammals and birds. This article reports an outbreak of botulism in two different flocks of ruminants at Paraíba, Brazil. In one, 85 out of 88 (96.6%) cattles died. In the other, 145 (96.7%) sheeps, 233 (57.8%) goats and 30 (96.8%) cattles died. Clinical signs were progressive paralysis, difficulties in moving, sialorrhoe and dyspnoe. Death occurred 24 to 48 hours after the beginning of clinic signs and at post-mortem examination no noteable changes were observed. Type C and D toxins were demonstrated in the intestinal contents and poultry litter by neutralization test in mice.
