Why are home-canned foods the source of botulism?
Since the canning process forces air out of food, the C. botulinum bacteria may find incorrectly or minimally processed canned foods a good place to grow and produce the toxin. Low-acid vegetables such as green beans, corn, beets, and peas, which may have picked up C. botulinum spores from the soil, are at risk.
