On March 27, 2025, China's NHC and the SAMR jointly released the National Food Safety Standard Food Microbiological Examination Enumeration of Escherichia coli (GB 4789.38-2025). This updated standard applies to the testing of E. coli counts in foods. The final standard will enter into force on September 16, 2025. At the time of the report, China hadn't notified WTO of this revised standard. This report provides unofficial translation of the final standard. Stakeholders should conduct their own review of the regulations to assess any market or regulatory effect on their business.
