Ensure reliable results of your microbiological tests

The international standard, ISO 11133:2014 (plus amendment 1:2018 and amendment 2:2020) outlines the regulatory requirements to be met in the preparation of culture media meant for use in the microbiological analysis of food, animal feed, and water meant for consumption or use in food production. Read this article from Issue 9 of the Analytix Reporter, produced by Merck, to find out more on the new Vitroids™ Certified Reference Materials (CRMs) compliant to ISO 11133:2014. 

Foodborne illnesses caused by contaminated food products are a major global concern. According to the World Health Organisation (WHO), every year about 10% of the global population falls ill after eating contaminated food, causing almost half a million deaths per year. While chemical contamination e.g. biotoxin poisoning is also a concern, the consumption of food contaminated by pathogens like viruses or bacteria causes most of the fatalities. The international standard, ISO 11133:2014 (plus amendment 1:2018 and amendment 2:2020) outlines the regulatory requirements to be met in the preparation of culture media meant for use in the microbiological analysis of food, animal feed, and water meant for consumption or use in food production.

Reliable and reproducible test results in microbiological analysis, necessitate a thorough quality check of the containing culture media. With Vitroids™ discs and LENTICULE^® discs Certified Reference Microorganisms (CRMs) from the Supelco^® portfolio of analytical products, a comprehensive range of microbiological reference materials is offered. These reference materials have a confirmed identity of the strain along with traceability to the strains from internationally recognized institutions like NCTC/NCPF or CECT. The products are certified reference materials produced in Merck's ISO/IEC 17025 and ISO 17034 accredited lab in Buchs, Switzerland. These CRMs are developed with an intention to provide laboratories with suitable ready-to-use microbiological controls for every media quality control test. The concentrations of CFUs are designed in ranges ensuring that no or only minimal dilution steps are required, thereby saving time and reducing the chances of cross-contamination.
