The prevent and control measures for the possible contamination of products by miscellaneous bacteria caused by the use of active bacteria should at least include the following:
(1) Provide quality specifications, sanitary indicators and corresponding test reports of active bacteria raw materials, including but not limited to bacterial composition, counting, chemical and microbial contamination indicators.
(2) Clear requirements on supplier selection, incoming inspection procedures (including but not limited to various quality specifications and hygiene indicators), storage and transportation conditions of raw materials, inbound and outbound storage management, etc.
(3) Ensure the consistency of strains in the production process, and provide control measures for the key processes of active bacteria raw materials using and site cleaning up.
(4) Batch test of active bacteria count and microbial contamination index in finished products.
