Food poisoning bacteria that won't die even if you boil it... "Be more careful in the fall."

Food poisoning bacteria are known to die when you heat food, right?

However, there are food poisoning bacteria that survive even boiled food, so special attention is needed in autumn when outings are frequent these days.

This is reporter Lee Moon-seok.

In autumn, when the daily temperature range is large, the temperature rises during the day, and food is likely to go bad.

In the past five years, 309 food poisoning cases have occurred in the fall alone, and nearly 6,000 people have suffered.

After Salmonella and pathogenic E. coli, the third most common food poisoning bacteria was Clostridium perfringens.

Perfringens bacteria are unfamiliar in name, but they are widely distributed in soil, rivers, animal intestines and feces.

When it is difficult to survive by heating, it turns into a heat-resistant spore, which is dormant, and then revived when the environment improves.

So, unlike other food poisoning bacteria, it can multiply again in boiled food.

Food poisoning caused by this fungus occurred a lot, especially in the fall, after eating foods cooked in large quantities of meat such as pork.

Last fall, 259 food poisoning patients occurred after eating pork bulgogi at an outdoor event hall in Chungbuk, and perfringens bacteria were found to be the cause.

To prevent this food poisoning, the central temperature must be heated sufficiently for at least 1 minute over 75 degrees Celsius when cooking in large quantities.

There are also precautions when storing and eating.

[Ban Kyung-nyeo / Director of Food poisoning Prevention Division of the Ministry of Food and Drug Safety: Divide into several containers, store them in the refrigerator, and if you eat stored food again, it is important to reheat at least 75 degrees Celsius.]

The Ministry of Food and Drug Safety also asked that gimbap and sandwiches commonly eaten on an outing should not be left in a sunny car, but to prepare an ice box and store it below 10℃.
