Kitchen waste will bury all kinds of health hazards. Many pathogenic microorganisms in kitchen waste are often "delicacies" of mosquitoes, flies and cockroaches. Mosquitoes inject saliva into the human body by biting the skin, and then spread the germs to people. Flies and cockroaches can carry more germs, and cockroaches reproduce very quickly. If there are old people, children or allergic people with low immunity at home, they are more likely to get sick if they contact or eat these foods contaminated by cockroaches, flies and so on.

The water content in kitchen waste is as high as 74%, which is very easy to ferment. If the kitchen waste is not thrown away in time every day and stored overnight, it will pollute the indoor air.

The grease in kitchen waste is also the main source of "gutter oil". People will have symptoms such as headache, vomiting, abdominal pain and gastrointestinal discomfort after eating; After repeated use, "gutter oil" also contains a large number of carcinogens, which will lead to chronic poisoning after long-term consumption.
