This work aims to describe an outbreak of botulism in poultry (Gallus gallus domesticus), in Pancas City, Espírito Santo State, Brazil. The birds were derived from a subsistence property with approximately 150 domestic fowls. The owner reported finding some birds lying on the floor and others exhibiting limited mobility. Ten animals in agony were euthanized, necropsied and had their blood serum collected. About 72 hours after the onset of clinical signs, 144 (96%) animals of the creation had already died. No postmortem changes were found at necropsies. Clostridium botulinum type C toxins were detected in the sera of euthanized chickens by mice neutralization tests. The observation of clinical signs, absence of post-mortem lesions and the result of mouse neutralization tests confirmed the diagnosis of botulism caused by C. botulinum type C. Unfortunately, the source of toxins was not found.
