Botulism • Clostridial bacteria • Can form spores which are

environmentally stable in many conditions

• Produces a neurotoxin (affects nerves)

• Cattle, sheep, horses, pigs, horses, goats, poultry and humans can all be affected

• Preventable, but difficult (and very unproductive) to treat • Predisposition to bone/carrion chewing can increase risk of

disease occurrence in unvaccinated livestock (Northern Aus).
