Last week, 3M Food Safety announced their 3M™ Molecular Detection Assay 2 – Cronobacter was designated by AOAC International as Performance Tested Method (Certificate #101703). The assay is compatible with their Molecular Detection System, which uses isothermal DNA amplification and bioluminescence detection to test for pathogens.
Cronobacter, a type of bacteria commonly found in powdered foods, supplements and baby formula, can survive for almost two years and exposure to an infant can be life-threatening.
“While less well known than other foodborne pathogens like Listeria or Salmonella, Cronobacter is no less dangerous – particularly because it preys on some of the most vulnerable populations,” says 3M Global Marketing Manager Carolina Riba. “It’s a point of pride for our team that the tests we’ve made for the dangerous pathogen were recognized by an organization like AOAC International.”
Using approved protocols set by the AOAC Research Institute, 3M’s testing process used an independent laboratory. They tested the assay on powdered infant formula, powdered infant cereal, lactose powder and an environmental surface.
Launched last August, the ready-to-use plate streamlines the testing process for lactic acid bacteria spoilage organisms. By assessing the bacterial levels acceptable for foods, the test can help companies extend product shelf life, reduce waste (the plates produce 66% less waste by weight and volume compared to certain agar methods), and potentially minimize recalls by allowing them to modify processing conditions or change cleaning and sanitation procedures. The test also provides accurate results in a shorter timeframe.
The AOAC Performance-Tested Method, Certificate #041701, is intended for a variety of foods (lactic acid bacteria is a concern for manufacturers of foods such as meat, fish, poultry, processed foods, produce, dairy products, dressings and sauces). Manufactured by 3M, the plate was tested on an environmental surface and a variety of food matrices as part of the validation process.
Neogen recently received approval from the AOAC Research Institute for its rapid and accurate AccuPoint Advanced ATP Sanitation Verification System.
Neogen’s AccuPoint Advanced is the first sanitation verification system to receive an AOAC approval, and this approval follows a recent study by NSF International that showed AccuPoint Advanced exceeded the performance of competitive systems.
“Each time we receive a validation from an independent third party on any of our tests, it provides further assurance to the food production and processing industry that our tests perform as expected,” said Ed Bradley, Neogen’s vice president of Food Safety. “The performance of our AccuPoint Advanced system in recent independent evaluations by AOAC and NSF is very gratifying. We developed the product with the goal of creating a new sanitation verification system that is superior to anything else on the market.”
The results in the AOAC validation report (Performance Tested MethodSM 091601) provided evidence that AccuPoint Advanced produces consistent and reliable data for evaluating sanitation program effectiveness in food processing and food services facilities.
AccuPoint Advanced is an enhanced version of its earlier AccuPoint test system. Improvements with AccuPoint Advanced include: improved sampler chemistry to produce more consistent results with even greater sensitivity; an enhanced instrument to produce even faster results (less than 20 seconds); and advanced Data Manager software to easily streamline the testing process by creating test plans and syncing important data, while keeping a permanent record of sanitation test results.
AOAC International is a globally recognized, independent forum for finding appropriate science-based solutions through the development of microbiological and chemical standards. The Applied Research Center at NSF International is a not-for-profit global research group that provides product development support to manufacturers and developers of products in the food safety, agriculture, clinical and life science markets.
Today DuPont announced that the AOAC Research Institute (AOAC-RI) approved a method extension of Performance Tested Method #100201 to include the company’s BAX System X5 PCR Assay for Salmonella detection. Introduced this past July, the PCR assay provides next-day results for most sample types following a standard enrichment protocol and approximately 3.5 hours of automated processing. The lightweight system is smaller and designed to provide more flexibility in testing.
“Many customers rely on AOAC-RI and other third-party certifications as evidence that a pathogen detection method meets a well-defined set of accuracy and sensitivity requirements,” says Morgan Wallace, DuPont Nutrition & Health senior microbiologist and validations leader for diagnostics, in a company release. “Adopting a test method that has received these certifications allows them to use the method right away, minimizing a laboratory’s requirements for expensive, time-consuming in-house validation procedures before they can begin product testing.”
The validation covers a range of food types, including meat, poultry, dairy, fruits, vegetables, bakery products, pet food and environmental samples.
A molecular detection assay for Listeria monocytogenes has been approved by the AOAC Performance Test Methods
(PTM) program. Developed by 3M Food Safety, the assay is based on isothermal DNA amplification and bioluminescence detection technologies. With a streamlined workflow that is 30% faster than the first generation assay, the new test is designed to provide expedited, simple and more accurate real-time pathogen detection.
Obtaining AOAC PTM status involved a thorough independent lab examination of the test method’s ability to accurately detect Listeria monocytogenes within a variety of foods. During the validation study, analyzed food samples included beef hot dogs, queso fresco cheese, vanilla ice cream, 4 % milk fat cottage cheese, 3% chocolate whole milk, romaine lettuce, bagged raw spinach, cold smoked salmon, deli turkey, raw chicken, cantaloupe, and various environmental surfaces (plastic, stainless steel, concrete). Achieving AOAC PTM approval certifies that the test kit is equivalent or better than standard reference methods, according to 3M Food Safety.
