Are samples of hotel New Year’s Eve dinner food still valid after 48 hours?

Hotel New Year’s Eve food samples need to be kept for 48 hours, not beyond 48 hours. The retained food samples should be placed in special sealed containers after cleaning and disinfection by variety, and stored under refrigerated conditions for more than 48 hours. The retained sample amount of each variety should be no less than 100g. In this way, when food safety incidents such as food poisoning occur, the source can be traced back to the cause in time. Therefore, the sample retention time is within 48 hours of storage under refrigerated conditions, not beyond 48 hours.
