Clostridium perfringens (C. perfringens) is one of the most common causes of food poisoning in the United States. CDC estimates C. perfringens causes nearly 1 million cases of foodborne illness each year. Find out more about this germ and steps you can take to prevent illness.
What is C. perfringens?
C. perfringens bacteria can be found on raw meat and poultry, in the intestines of animals and humans, and in the environment. Some strains produce a toxin that causes diarrhea.
What are common food sources of C. perfringens?
Meat and poultry are common sources of C. perfringens infections. C. perfringens infection can result when certain foods, such as large roasts or big pots of stew, are not kept at proper holding temperatures before serving. Outbreaks tend to happen in places that serve large groups, such as hospitals, school cafeterias, prisons, and nursing homes, or at events with catered food.
Who is at risk of C. perfringens food poisoning?
- Pocket-sized quick-read thermometer that’s great for measuring temp in thin cuts of meat, fish or poultry
- 5-inch stainless steel stem can get a reading in 6-8 seconds; stainless steel housing surrounding the digital readout
- Large-digit readout, data-hold capabilities, 10-minute auto-off, plastic sheath with pen clip
- Temperature range of -40 to 450 degrees F (-40 to 230 degrees C)
- Powered by LR44 button battery (included); backed by 5-year limited warranty
Anyone can get food poisoning from C. perfringens.
What are the symptoms of C. perfringens food poisoning?
People with C. perfringens food poisoning develop diarrhea and abdominal cramps within 6 to 24 hours (typically 8 to 12). The illness usually begins suddenly and lasts for less than 24 hours. Dehydration may occur. This infection does not cause fever or vomiting and is not passed from one person to another.
How can C. perfringens food poisoning be prevented?
Cook and keep food at the correct temperature
Food, especially roasts of beef or poultry, should be cooked to a safe temperature, and then kept at 140°F (60°C) or warmer or 40°F (4.4°C) or cooler. These temperatures prevent the growth of bacteria that might have survived cooking. Meat dishes should be served hot, within 2 hours after cooking.
Refrigerate leftovers and reheat them properly
Leftover foods should be refrigerated at 40°F or colder as soon as possible and no more than 2 hours after preparation. It is okay to put hot foods directly into the refrigerator. Large pots of food, such as soups, stews, and large cuts of meats, such as roasts, should be divided into small quantities for refrigeration so they will cool quickly enough to prevent bacteria from growing. Leftovers should be reheated to at least 165°F (74°C) before serving.
When in doubt, throw it out!!
Foods that have dangerous bacteria in them may not taste, smell, or look different. Any food that has been left out too long may be dangerous to eat, even if it looks okay.
Use this chart and a food thermometer to ensure that meat, poultry, seafood, and other cooked foods reach a safe minimum internal temperature.
Remember, you can’t tell whether meat is safely cooked by looking at it. Any cooked, uncured red meats – including pork – can be pink, even when the meat has reached a safe internal temperature.
After you remove meat from a grill, oven, or other heat source, allow it to rest for the specified amount of time. During the rest time, its temperature remains constant or continues to rise, which destroys harmful germs.
