Incubation period of Clostridium botulinum (foodborne illness)?

Incubation period is the time from eating contaminated food to the start of symptoms. For foodborne botulism caused by preformed toxin in improperly processed foods, symptoms typically appear about 12 to 36 hours after ingestion, with many sources noting usually 12-36 hours and a broader range that can start as early as around 6 hours and extend to about 36 hours. This makes 6-36 hours (usually 12-36) the best match, as it aligns with the common onset window. Times like 1-2 hours or 3-6 hours are too short for botulinum toxin to produce symptoms, while 48-72 hours exceeds the usual window observed in most cases.
