The pathogenic organism was Clostridium perfringens. Generally, cases involving this organism occur when product like meat are temperature abused, allowing the organism to grow in the food product. "In most instances, the actual cause of poisoning by this organism is temperature abuse of cooked

foods. Small numbers of the organism often are present after the food is cooked, due to
germination of its spores, which can survive high heat and can multiply rapidly as a result of a
fast doubling time (<10 minutes for vegetative cells), depending on temperature and food matrix.
Therefore, during cool-down (109-113°F) and storage of prepared foods, this organism can reach
levels that cause food poisoning much more quickly than can other bacteria." Disease results from ingestion of large numbers of C. perfringens (FDA).
