Clostridium perfringens

Clostridium perfringens is a spore-forming bacteria that is found in many environmental sources, as well as in the intestines of humans and animals. C. perfringens is often found in raw meat and poultry, and is one of the most common causes of foodborne illness in the United States. CDC estimates that C. perfringens causes about 1 million foodborne illnesses in the United States. It prefers to grow in certain conditions such as when food is kept at unsafe temperatures and in environments with very little or no oxygen. It can multiply very rapidly under these conditions.


 

Transmission

Transmission

Everyone is susceptible to becoming ill from Infection with C. perfringens. Infection with C. perfringens is caused by 

  • Eating food contaminated with large numbers of C. perfringens bacteria which produce enough toxin in the intestine to cause illness.
    • C. perfringens bacteria grow in food.
      • During cooling and holding of food at temperatures between 40°F and 140°F, the spores germinate, and the bacteria grow.
      • If the food is served without reheating to kill the bacteria, live bacteria may be eaten.
      • Beef, poultry, gravies, and dried or precooked foods are common sources of C. perfringens infections. 

Outbreaks of C. perfringens food poisoning can happen in settings where large groups of people are served and keeping food at an adequate temperature can be difficult, such as 

  • Hospitals
  • Schools
  • Prisons
  • Nursing homes
  • Social gatherings 

Past infection does not make a person immune to C. Perfringens.

Prevention
  • Cook food to a safe internal temperature
  • Keep cooked food at 140°F or hotter and 40°F or colder if it is not going to be eaten right away
  • Refrigerate leftovers at 40°F or colder within two hours after cooking or if it is not being heated by an appliance. Refrigerate within an hour if the food is exposed to temperatures above 90°F, like a hot car or picnic
    • Hot food can be put directly into the refrigerator
    • Divide large pots with soups or stews, and large cuts of meat into smaller quantities so they can cool quicker
  • Reheat leftovers to 165°F or hotter before serving
