The botulism toxin can form in oxygen-free environments such as in jars of low-acid foods (including vegetables and meat) canned improperly in a pressure canner. Botulism can be fatal unless an antitoxin is administered. Later signs include blurred or double vision, difficulty swallowing, fatigue and difficulty breathing. The first signs of botulism are flu-like, including nausea, vomiting and dizziness. Symptoms appear within 12 to 36 hours of consuming the food. Consuming the toxin can paralyze the nervous system and lead to suffocation.
