What is the cause of most C. botulinum poisonings in the U.S.?

Explanation:
Most C. botulinum poisonings in the United States come from home-canned vegetables and fruits because the toxin develops in anaerobic, low-acid environments that can occur in improperly processed home canning. C. botulinum spores can survive typical boiling temperatures, and if jars are sealed and stored at room temperature, the growing colonies can produce toxin inside the food. Commercial canning uses validated processing that applies higher heat and acid control to destroy spores, making outbreaks far less common. Fresh produce and dried herbs don’t routinely create the same safe, sealed, low-acid conditions, which is why they’re not the main source of these poisonings.
