C. perfringens food poisoning is caused by infection with the
Clostridium perfringens (C. perfringens) bacterium. C. perfringens is found
frequently in the
intestines of humans and many animals and is present
in soil and areas contaminated by human or animal feces.
In most cases, C. perfringens
food poisoning results when you eat improperly cooked and stored foods.
Normally, bacteria are found on food after cooking, and these bacteria can
multiply and cause C. perfringens food poisoning if the
foods sit out and cool before refrigerating. Commonly infected foods include
meats, meat products, and gravy.
Symptoms of C. perfringens food poisoning include intense abdominal cramps
and watery diarrhea. Your symptoms usually appear 6 to 24 hours after eating

loose stool you have. You can also use a sports drink, such as Gatorade. Soda
and fruit juices have too much sugar and not enough of the important
electrolytes that are lost during diarrhea, and they
should not be used to rehydrate.
Try to stay with a healthy diet as much as possible. Eating healthy foods will help you to get enough
nutrition. Doctors believe that eating a healthy diet will also help you feel
better faster. But try to avoid foods that are high in fat and sugar. Also

You can prevent C. perfringens
food poisoning by cooling and storing foods correctly (adapted from the U.S.
Centers for Disease Control and Prevention).
It is important to pay particular attention to food
preparation and storage during warm months when food is often served outside.
Bacteria grow faster in warmer weather, so food can spoil more quickly and
possibly cause illness. Do not leave food outdoors for more than 1 hour if the
temperature is above 90°F (32°C), and never leave it outdoors for more than 2 hours.
