Working in a supermarket requires a first-class health certificate. Class A health certificate is mainly applicable to catering, food, beauty, washing, drug production and sales personnel. The staff will be in direct contact with food, and the requirements for physical examination will be slightly stricter. The culture of Salmonella and Shigella in stool must be negative, and regular physical examination is needed.
The health certificate is the proof of preventive health examination, which proves that the examinee has the health quality to engage in the prescribed business.
