Noteworthy Points for Stakeholders
As a significant part of risk management, the control over pathogen limit in food shall always be emphasized. Despite some food categories are not listed in this standard, food enterprises still need to check the food ingredients they use, to ensure there's no violation of pathogen limit in food ingredients. The following points should be especially noted:
GB 29921-2021 has taken effect on Nov. 22, 2021, while GB 31607-2021 will be effective from Mar. 7, 2022. Food products produced after the implementation dates shall conform to the new standards.
For dairy and special dietary food, in addition to their corresponding product standards, they also have to meet the pathogen limit specified in GB 29921-2021.
For manufacturer and operation enterprise of aquatic products, RTE fruit/vegetable products and frozen drinks, attention needs to be paid to the pollution risk and over-limit risk of Listeria monocytogenes.
