If it is printed with clean and tidy bronzing, laser laser, acupuncture or steel seal, it is basically true. In general, many brands of large companies print production dates in these ways to prevent counterfeiting.

If the production date is inkjet printed, first check whether these numbers are blurred, ghosted or ink. If it is a non-steel seal or a needle-punched production date, it can be wiped by hand. If it is really printed, it will not be erased. If it is printed later, it may be blurred.

Precautions:

1. When purchasing prepackaged foods, you should carefully check the production date, shelf life, manufacturer and other important information. Refuse to buy expired food, three-no food, food with abnormal sensory characteristics, etc. When consumers find the above-mentioned food, they should report it to the local market supervision and management department (US Food and Drug Administration) in time.

2. Choose a catering unit with clean environment and good hygiene, hang a catering service license or a food business license in the store, and supervise the Facebook sign displayed on the bulletin board to smile or laugh. Don't eat food provided by roadside and open-air mobile stalls, and don't order cold dishes in catering units without cold dishes.

3. Buy food or ask for and keep relevant bills as much as possible after consumption by catering service units, so as to trace the responsibility after the accident.
