Enjoy a watermelon. How can it be so serious?

You know, refrigeration in the refrigerator doesn't mean sterility. The cold storage temperature is generally 4~5℃, and some psychrophilic bacteria can still survive. In addition, low temperature only delays the reproduction of bacteria and cannot kill them.

Watermelon will still breed bacteria in the refrigerator if it is stored in the wrong way.

Kai Zhong, an associate researcher in the Risk Communication Department of the National Food Safety Risk Assessment Center, suggested that watermelons that have not been eaten should not be preserved for a long time.

Cut watermelons are generally stored at room temperature for up to 4 hours and need to be refrigerated in time; At the same time, be sure to cover it with clean plastic wrap, or dig out the remaining watermelons and put them away.

And this uncle, not only didn't cover the watermelon with plastic wrap, but also stored it with other foods! That night, bacteria propagated desperately on the surface of watermelon.

In fact, this uncle ate a piece of "bacteria-flavored" iced watermelon and suffered from "abdominal pain". (Experts remind: It is best to eat watermelons now, and it is best not to put the cut watermelons in the refrigerator for more than 12 hours. In addition, when you take the watermelon out of the refrigerator to eat, you can cut off the surface of about 1 cm first. )
