Compliance overview
Scope and applicability
This standard applies specifically to feed additives produced through fermentation using Lactobacillus acidophilus as the microbial strain. It is relevant for manufacturers and distributors involved in the animal nutrition and feed industry. It is mandatory for all products marketed as Lactobacillus acidophilus feed additives within China.
Technical requirements
The standard outlines comprehensive specifications for the final product. It mandates that the strain used must be definitively identified as Lactobacillus acidophilus. The product appearance should typically be a powder, granular, or liquid form, free of foreign matter and off-odors. Regarding physicochemical properties, the standard sets strict criteria for viable cell count (CFU/g or CFU/mL), moisture content for solid products, and particle size for powdered forms. Manufacturers must ensure these core parameters meet the specified minimum or maximum thresholds to achieve compliance. Furthermore, the standard defines rigorous hygiene parameters to ensure product safety. This includes maximum limits for heavy metals such as arsenic, lead, mercury, and cadmium. It also restricts the presence of mycotoxins, including Aflatoxin B1 and Zearalenone, as well as pathogenic microorganisms like Salmonella.
Testing methods
Testing procedures involve sensory evaluation for appearance and traits. Microbiological identification and viable cell counting are conducted in accordance with referenced national standards. Additionally, specific analytical methods are prescribed for measuring moisture, particle size, heavy metals, mycotoxins, and pathogens. Strict sampling rules must be followed to ensure representative and uncontaminated testing batches.
