Setting up a stall can lead to food poisoning. Cold dishes poured with oil and set up in stalls are cold foods that are not heated before eating. If you are not careful during the processing or store them improperly, they are easily contaminated by bacteria. After eating, they will cause intestinal diseases or food poisoning, so they cannot be sold in stalls. . Cold Dishes (foreign name: Cold Dishes), commonly known as cold dishes in the catering industry, are dishes with a unique style and highly technical presentation. They are eaten cold whenever they are eaten, so they are called cold dishes.
