Botulism is caused by the exotoxins of Clostridium botulinum. The disease has also been called “limberneck,” describing one of its clinical symptoms. It occurs worldwide and often affects wild waterfowl, especially in warmer weather, when C. botulinum thrives in stagnant water, but all types of poultry with or without outdoor access have been affected. With rare exceptions, botulism in humans and poultry is caused by different toxin types. However, these exceptions cause concerns about the risk outbreaks in poultry may pose for public health. Flocks with a history of botulism might be slaughtered if they are free of symptoms for several weeks. Meat from flocks exhibiting clinical signs is not suitable for human consumption. The decision to slaughter or euthanize a flock should be made after consulting the relevant authorities.
