Which of the following pathogens are associated with watery diarrhea after an incubation period of 8 to 14 hours?

Bacillus cereus and Clostridium perfringens Bacillus cereus strains can produce two different toxins: a heat stable toxin that can lead to an illness after 2 to 7 hours and a heat-labile toxin that causes disease manifestations 8 to 14 hours after ingestion. The syndrome of Clostridium perfringens diarrhea usually occurs 8 to 14 hours after ingestion of the preformed toxin.
