In fact, it's not just cold cucumber, but also cold preserved eggs and cold shredded potatoes. These things need qualifications, otherwise they will probably be punished like many bosses in Anhui, and the amount of punishment is not small. A plate of cucumbers is only a dozen dollars at most. How many plates of cucumbers do they need to sell to earn their money back? Because cold dishes are cold-processed, of course, they are also cold, so they don't need to be heated before eating or during processing. It will be easily contaminated by bacteria, and customers will get sick or get food poisoning after using it. Cold dishes themselves have always been listed as foods with high safety risks, so they can't be sold if they want to. If they want to sell cold dishes, they will have stricter requirements on equipment, facilities and operation, and must maintain strict sanitary conditions. If the customer causes poisoning, will it be serious? These cold dishes will have certain bacteria if they are not heated.
Many people prefer to eat cold dishes in summer, so I suggest you go to a regular shopping mall or a supermarket that meets the requirements. At the same time, you should also pay attention to the publicity of employee health certificates. Don't go to the roadside stalls to buy those cold dishes, because the hygiene requirements in those places are not up to standard at all, and there is no professional qualification. If there is any problem, no one can be responsible, only admit that it is unlucky.
