Spore-forming bacteria that survive cooking and later produce toxin in the gut are a classic cause of foodborne illness with a mid-range incubation and abdominal symptoms. Clostridium perfringens fits this pattern: its spores can survive cooking, then germinate in the small intestine and release toxins that cause watery diarrhea and abdominal cramps. The illness typically shows up within roughly 6 to 24 hours after eating, which matches the scenario described. It’s commonly associated with improperly held meats and gravies, where spores can persist and germinate in the gut.

If you compare the other options, the timing and symptom profile point away from them. Staphylococcus aureus food poisoning is driven by preformed toxins and usually yields rapid vomiting rather than profuse diarrhea. Clostridium botulinum causes a neurotoxic illness with paralysis rather than diarrhea. Bacillus cereus can also cause diarrhea within a similar window, but the hallmark emphasis for this scenario—the spores surviving cooking and germinating in the gut to produce a diarrheal illness with cramps—best aligns with Clostridium perfringens.
