In May 2026, Bio-Rad Laboratories, Inc. successfully achieved MicroVal certification for its EZ-Check Listeria monocytogenes Kit, validating the method for the detection of Listeria monocytogenes across a broad range of food products and production environmental samples.
The validation study was conducted by Q Laboratories in accordance with ISO 16140-2:2016 and ISO 16140-2:2016/Amd. 1:2024. The method was evaluated against the reference methods ISO 11290-1:2017, supported by the relevant sample preparation and surface sampling standards.
The certified scope covers seven major categories: raw and pasteurized dairy products, ready-to-eat (RTE) and ready-to-reheat (RTRH) meat and poultry, cooked fishery and seafood products, raw fruits and vegetables, multicomponent foods, egg and egg products, and production environmental samples.
The validation also includes an alternative confirmation procedure, enabling direct plating from the primary enrichment onto RAPID’ Listeria, RAPID’ L. mono, and ALOA agar, followed by confirmation of typical colonies using another MicroVal ISO 16140-6 validated method, such as the Bruker MALDI Biotyper (MBT).
This certification expands the range of validated rapid methods available to food testing laboratories, supporting reliable detection of Listeria monocytogenes and strengthening food safety monitoring across diverse food matrices and production environments.
The certificate and the summary report (number 2025LR136) are available on the page issued certificates.
