The Food Hygiene Law clearly stipulates that the validity period of health certificate is 1 year. After the expiration, the old certificate is worthless. Just like there is no health certificate, the new certificate must be re-examined. If the health certificate expires, the health administrative department of the local people's government at or above the county level shall order it to make corrections within a time limit and give a warning. If no correction is made within the time limit, a fine of more than 5,000 yuan 1500 yuan shall be imposed.
