GB 7300.507-2025 is an upcoming mandatory Chinese national standard for Feed additives—Part 5：Live microorganisms—Enterococcus faecalis. It appears in the Food compliance cluster with a product safety focus and has an implementation date of Jan 1, 2027.
Applicability depends on product scope, certification route, competent authority notices and transition rules. Requst for the translation or verify source before using this record in a compliance decision.
Compliance overview
Scope and applicability
This standard applies to solid feed additives containing Enterococcus faecalis, manufactured through processes such as liquid fermentation, separation, and drying. It is specifically designed for products entering the Chinese animal feed market and does not cover liquid formulations or other microbial species.
Technical requirements
The standard outlines the physical, chemical, and biological parameters for Enterococcus faecalis. It mandates that the product appearance be a uniform powder or granule without off-odors or clumping. A critical requirement is the strain identification, which must be confirmed through morphological, physiological, biochemical, and molecular biology methods. Manufacturers must ensure the strain matches the defined characteristics precisely. The standard also sets strict quality indicators, including minimum viable count limits, maximum moisture content, and particle size pass-through rates for powdered forms. Furthermore, it establishes rigorous hygiene limits for heavy metals (such as arsenic, lead, mercury, and cadmium) and mycotoxins. Compliance with these contaminant limits is mandatory to ensure feed safety. Pathogenic microorganisms like Salmonella must not be detected, and there are strict ceilings for coliforms and mold counts.
Testing methods
Testing involves a combination of microbiological culturing and analytical chemistry. Strain identification utilizes PCR amplification and 16S rRNA sequencing, alongside physiological biochemical tests. Viable bacteria counting is performed using specific plate methods on KF Streptococcus Agar. Accurate enumeration is critical for quality assessment. For hygiene and chemical parameters, the standard references established Chinese national methods for determining heavy metals, mycotoxins, and pathogenic bacteria.
FAQs
What products are regulated under GB 7300.507-2025?
This standard applies to solid feed additive products made from Enterococcus faecalis strains through processes like liquid fermentation, separation, and drying. It is specifically designed for the feed industry and does not cover liquid or other non-solid formulations.
Are there any updates from the previous version of GB 7300.507?
It is a new standard set to be implemented on 2027-01-01. As part of the GB 7300 series, it establishes updated and specific technical requirements and testing methodologies for this particular microorganism, ensuring standardized quality control across the industry.
How does GB 7300.507-2025 differ from ISO standards for feed additives?
While it shares similarities with international microbiological testing guidelines, this standard mandates specific Chinese methodologies, such as using KF Streptococcus Agar for isolation and requiring a 16S rRNA sequence match of over 99% with the CGMCC 1.2135T reference strain. Compliance with these exact local procedures is mandatory for market access.
