What food causes botulism?
Low-acid foods are the most common sources of botulism linked to home canning. These foods have a pH level greater than 4.6. Low-acid foods include most vegetables (including asparagus, green beans, beets, corn, and potatoes), some fruits (including some tomatoes and figs), milk, all meats, fish, and other seafood.
How do adults usually get botulism?

What kills botulism?
Despite its extreme potency, botulinum toxin is easily destroyed. Heating to an internal temperature of 85°C for at least 5 minutes will decontaminate affected food or drink. All foods suspected of contamination should be promptly removed from potential consumers and submitted to public health authorities for testing.
What is the best way to prevent botulism?
Can botulism be prevented?
- Refrigerate foods within 2 hours after cooking. Proper refrigeration prevents the bacteria from producing spores.
- Cook food thoroughly.
- Avoid food containers that appear damaged or bulging. (These can be signs of gas produced by the bacteria.)
What is the most common form of botulism?
botulinum spores germinate and produce toxin in a contaminated wound or abscess. The most common form of botulism in the United States, infant botulism, is caused when ingested C. botulinum spores colonize and subsequently produce toxin in the intestines of affected infants.
Does botulism grow in vinegar?
botulinum needs a near-oxygen-free environment to grow, and doesn’t like acid. Air and acids such as vinegar, lemon and lime juice help to keep us safe from food-borne botulism.
Can you cook out botulism?
