the main thing is to make clear who is in charge, so that it can be verified. The format should be a letter of appointment to do a good job in food safety according to the needs of our work, and so on. So-and-so is appointed as the person in charge of the unit canteen, responsible for the specific food safety and daily management of the unit canteen. Signature and seal of legal person. Year, month and day, and the relevant certificates of legal person and the certificate of the person in charge shall be attached together. I hope I can help you.
