Microbial contamination includes bacterial contamination, contamination by viruses, fungi and their toxins. As estimated by the World Health Organization, 70% of the hundreds of millions of food-borne disease patients in the world each year are caused by eating food and drinking water contaminated by various pathogenic microorganisms. Microbial food poisoning ranks first in the factors affecting food safety in China. Among microbial pollution, the bacterial pollution is the most extensive, the most influential and the most problematic one. In the food processing, storage, transportation and sales process, raw materials polluted by the environment, incomplete sterilization, improper storage and transportation methods, and careless hygienic operations. These are the main reasons that cause bacteria and pathogenic bacteria to exceed the standard.

Tests according to product type, product standard requirements and trade party requirements;

Testing standards include GB 4789 series standards, Cosmetics Safety Technical Specifications, Chinese Pharmacopoeia, SN/T 1869 (PCR method), GB 15979, GB 14934, GB 5750 series standards, foreign or international standards such as: FDA/BAM standards, ISO standards, AOAC standards, etc.

The Microbiology Laboratory of the Food and Agriculture Division of the Ti Testing and Certification Group has rich experience in microbiological testing field. Not only we can perform non-pathogenic bacteria testing, but also can conduct food-borne pathogens testing in a laboratory with the secondary protection level. We have full capabilities of microbiological testing items for various food, feed, daily chemicals, additives, raw materials, soil, water quality, ambient air and tableware, All test items have obtained CMA and CNAS qualifications，Specific parameter detection services are as follows:
