It's summer. Food is easy to hurt in summer, and the topic of food poisoning has begun to appear. In particular, the number of bacterial food poisoning cases peaked in August, and it is said that we cannot be alert in September.

Therefore, in mid-August 2012, the Sanitary Microbiology Research Center actually cooked beef and investigated the number of germs on cutting boards and tablecloths used in the process. In this experiment, we used raw beef that had been left at room temperature for about an hour, assuming that we made a detour after shopping at a supermarket.

Immediately, the result of the experiment!


Experimental results: Viable bacteria on cutting board and table cloth after cooking beef

After wiping the cutting board, 3,500 / 10 cm2 germs were detected on the table cloth. When the table cloth was spread in the kitchen and left at room temperature (temperature 30 ° C (86 ° F) to 33 ° C (91.4 ° F), humidity 50% to 55%) for 10 hours, it grew to 24,000,000 pieces / 10 cm2, which is about 6,800 times larger!

Even if you wash the table cloth where the bacteria have propagated by hand with tap water, 200,000 pieces / 10 cm2 of germs remain on the table cloth. If you wipe the table or tableware with such a table, it will spread the germs.

■ Then what should I do?

This time, the Hygiene and Microbiology Research Center will also teach you how to deal with it. It will be saved.

First of all, a cutting board!

After cutting raw meat and fish, wash the cutting board before use. It seems to be even safer if you pour boiling water after washing, or use different cutting boards for meat and vegetables. It is also effective to purchase raw meat at the end of shopping and store it in the refrigerator or freezer immediately after returning.

Next, Daifukin!

If the table cloth is left dirty or dried indoors, germs will grow. After each use, it is important to wash it thoroughly with detergent and dry it in the sun to dry it completely. In addition, alcohol exerts bactericidal activity against food poisoning bacteria in a short time, so when using a table cloth, alcohol sterilization wiping is more effective. However, alcohol does not have a long-lasting sterilization, so it is very effective to do it as a daily habit.



is. It's hot and hot, and it's easy to be lazy, but let's clean the kitchen and survive the summer.
