1. Humidity and high temperature (20~40 degrees) are easy to breed bacteria. For example, if the tableware is not cleaned in summer, a large number of Escherichia coli will breed after 3 to 4 hours, and it is easy to get gastroenteritis after use.

2. The common method to inhibit bacterial reproduction in catering industry is high-temperature cooking tableware. Ultraviolet light illuminates the storefront (usually when it is closed at night). Clean the floor and kitchen regularly and spray disinfectant (peracetic acid).

Food is generally refrigerated at low temperature. Don't sell too much frozen food. Bacteria will multiply slowly at low temperature and deteriorate after a long time.
