How to avoid food-borne illness

Personally, I don't eat those bentos sitting at room temperature anywhere.

Have you ever watched the YT videos of Dianxi and Li Ziqi ? They always use same chopping board and just one cleaver to cut both meat and vegetables. Infact, it is how it is being used in Chinese culture and average life expectancy of Chinese is 77.

If you follow the stricy rules like that in the kitchen, you will have some kind of phobia.

One needs germs and bacteria along with virus material to stay healthy. Antibiotics are the main reason why you get food poisoning because after you kill all the wonderful healthy bacteria in your gut works, you are vulnerable to getting sick.

The chopping board issue is easily solved. You prepare all your vegetables first and do the meat last. Then whilst everything is cooking thoroughly wash the chopping board and knives with hot soapy water and store them away for use next time.
