Botulism in Bahia: An overview
What is botulism?
Botulism is a rare but potentially fatal paralytic illness caused by a neurotoxin produced by the bacterium Clostridium botulinum. The toxin blocks nerve signals, leading to paralysis of muscles, including those involved in breathing and swallowing. Symptoms usually begin 12-36 hours after consuming contaminated food, and can include nausea, vomiting, diarrhea, blurred vision, slurred speech, difficulty breathing, and paralysis.
