Gutter oil mainly refers to the oil that is made by simple processing and refining of greasy floating objects in the sewer or leftovers and leftovers (commonly known as swill water) in hotels and restaurants.

　　Many food processing stalls and catering establishments use gutter oil to fry food, make pastries or snacks, or even fry directly. It has long been no secret. However, "Here from 2 million tons to 3 million tons of drain oil returns to the table every year," exposed by Professor He Dongping of Wuhan Institute of Technology, still surprised the Chinese people. As the leader of the National Oil and Fats Working Group of the National Cereals and Oils Standardization Committee, Professor He has also conducted field investigations on the return of drain oil to the dining table. The figures provided are both true and sensitive, and are "disgusting" to consumers. A lot of reports have said eloquently that almost every one of us who has eaten outside has eaten drain oil.

　　When a reporter interviewed me, let me talk about the hazards of drain oil, such as cancer, poisoning, and disease. But to be honest, in addition to the possible presence of aflatoxin, the known, harmful, and indestructible components of the drain oil are difficult to determine. Of course, I am definitely not saying that the drainage oil is harmless or harmless. I think the more critical issue is, for example, a rice ball that has been eaten by someone else halfway and dipped in his saliva, even if it is 100% sure he is healthy (without any infectious diseases), do you want to eat it? I think Most people choose NO. Ditch oil is actually consumed garbage. Garbage is not necessarily toxic and harmful, but we should not eat garbage, because it seriously reduces our quality of life and keeps us on par with pigs.

The report of 　　ditch oil has attracted extensive attention. After everyone is surprised, accused, and cursed, will they reduce the number of times they go to small stalls, black shops, unlicensed restaurants, and unhealthy catering establishments? Or not go out to eat as much as possible, go home and eat with their families? I think no. Everyone will soon forget about the hidden dangers such as drain oil, dirty disposable chopsticks, fake mutton and so on. Some people will say that life still has to continue, even if it is to eat with garbage.
