Symptoms of botulism usually start around 7-10 days after contamination. The botulinum toxins block the action of the nerves on the muscles. As a result, the first signs of botulism are muscle weakness and poor co-ordination. In the early stages the horse has muscle tremors.
Botulism is a rare but serious illness caused by a toxin that affects the nervous system and can cause paralysis. The bacterium Clostridium botulinum, which is found commonly in nature, produces this toxin. There are several types of botulism, including foodborne botulism, which is caused by eating foods that contain the botulinum toxin. Botulism is a serious illness that should be treated as a medical emergency. Severe cases of botulism can lead to paralysis of the breathing muscles, respiratory or heart failure and death. If not diagnosed and treated, death from respiratory failure can occur within 1 to 10 days.
