Romer Labs Launches AOAC-Certified RapidChek® Listeria monocytogenes
Romer Labs® is introducing a new pathogen testing system: RapidChek®Listeria monocytogenes. AOAC, the independent, third-party organization devoted to evaluating methodology for food microbiology, has certified in its Performance Tested MethodsSM program the testing system for detecting the pathogen on environmental surfaces and ready-to-eat foods, including hot dogs, frozen breaded chicken, frozen cooked shrimp, cured ham and ice cream.
L. monocytogenes is a significant human pathogen that can contaminate, among other foodstuffs, ready-to-eat (RTE) meat and poultry. As with other Listeria species, L. monocytogenes is able to survive and thrive in cool, damp conditions where other bacteria cannot. An aggressive and verifiable sanitation program is therefore necessary to avoid cross-contamination of processing equipment in production plants.
Children and those with weakened immune systems are particularly vulnerable to L. monocytogenes. As a result, the Food and Safety Inspection Service (FSIS) at the USDA maintains a “zero-tolerance” policy for the pathogen in RTE meat and poultry products. The USDA, FDA, EFSA and other national and international regulatory bodies recommend and enforce hygienic measures that call for frequent testing of surfaces in the environment that come into contact with food ingredients as well as finished products.
RapidChek®Listeria monocytogenes is designed to meet this diagnostic need and provides results days faster than ISO, USDA and FDA methods. It combines a sensitive immuno-detection strip with a single proprietary enrichment media. After enrichment, highly sensitive and specific strips indicate the presence of L. monocytogenes in only 10 minutes.
“We are delighted that our AOAC-certified food pathogen detection tools now include a specific testing solution for Listeria monocytogenes,” said Romer Labs® R&D Director Kurt Brunner. “Food producers can leverage the same media they prepare for RapidChek®Listeria NextDay™ to test for L. monocytogenes; if the first test is positive, the same media can be used to deliver results for L. monocytogenes just one day later. Together, these two solutions form a comprehensive system for on-site Listeria detection that helps food producers discover and control the presence of this pathogen in their production facilities.”
He continued: “While the AOAC Performance TestedSM certification underscores the scientific soundness of the product, RapidChek® Listeria monocytogenes also has considerable business benefits, including unlimited scalability, ease-of-use with a one-step enrichment process, the need for minimal training, and a long shelf life at room temperature. We are proud to be bringing this new method to the food safety market.”
