scum in the catering industry refers to those practitioners or businesses who ignore food safety, health and quality. In the catering industry, some irresponsible merchants pose a great threat to the health and life safety of diners by using inferior or expired ingredients, adding prohibited substances and ignoring hygiene requirements. They not only defiled the reputation and image of the catering industry, but also committed moral and legal crimes, which should be severely cracked down and punished.

The problem of scum in the catering industry is exposed, in the final analysis, because the catering industry is not strictly regulated. In particular, some small catering shops and vendors lack official supervision and social supervision, and it is easy to slide into bad business practices. Therefore, only by strengthening the supervision of the food market and strengthening the punishment measures of laws and systems can we effectively curb the existence of scum in the food industry and protect food safety and consumer interests.

When choosing restaurants and brands, consumers should pay attention to the comparison of price and quality, and pay more attention to those schemes that are too low in price and "get what you pay for". At the same time, it is suggested that consumers should take the steps of "official website inquiry and business inquiry" before meals to know the qualification details of food companies, so as to avoid being cheated because of carelessness. Only when consumers take the initiative to protect their own rights and enhance consumption standards can they force the scum of the catering industry to properly solve problems and rebuild the credibility of the industry.
