Botulism in Bahia: A Rising Concern
Understanding Botulism
Botulism is a serious paralytic illness caused by a neurotoxin produced by the bacterium Clostridium botulinum. It can affect both humans and animals through the consumption of contaminated food, water, or soil containing the toxin.
Transmission and Symptoms
Botulism typically occurs via ingestion of preformed botulinum toxin, but it can also result from wound infections or inhalation of the toxin. Symptoms usually develop within 12-72 hours of exposure and may include:
*- Nausea and vomiting
- Double vision or blurred vision
- Drooping eyelids
- Difficulty swallowing and speaking
- Paralysis of arms, legs, and respiratory muscles
