Clostridium perfringens is a spore-forming gram-positive bacterium that is found in many environmental sources as well as in the intestines of humans and animals. C. perfringens is commonly found on raw meat and poultry. C. perfringens produces a toxin that causes illness. The symptoms of C. perfringens food poisoning are watery diarrhea and abdominal cramps within 6 to 24 hours (typically 8-12). The illness usually begins suddenly and lasts for less than 24 hours. Persons infected with C. perfringens usually do not have fever or vomiting. The very young and elderly are most at risk of C. perfringens infection and can experience more severe symptoms that may last for 1-2 weeks. Complications include dehydration in severe cases.
