Listeria

A poster by Thermo Scientific presented ay the 2022 IAFP Conference in August showed validation methods of the company’s SureTect Listeria monocytogenes and Listeria species PCR Assays, which led to AOAC recognition for official method of first action.

For the unpaired collaborative study, Evangelos J Vandoros, et al, compared the SureTect Listeria PCR Assays Method to the method outlined in the FDA-Bam Chapter 10. The matrix used for the study was full-fat cottage cheese with a test portion of 25g.

The researchers validated both SureTect Listeria PCR Assays (Listeria species and Listeria monocytogenes) in this study, as they follow the same method protocol and are validated for the same matrices.

Outcomes showed consolidated dLPOD data from 12 collaborators for the SureTect Listeria PCR methods and the FDA-BAM Chapter 10 reference method. The data was within confidence intervals showing that there was no significant difference between the SureTect methods and the reference method. The time to result was less than 24 hours.

Based on these findings, the SureTect Listeria monocytogenes and Listeria species PCR Assays were both granted AOAC Official Methods First Action

The validated categories for the assays include milk and dairy, fresh produce, seafood, raw meat, ready to eat/reheat and environmental,

3M Food Safety Test for Cronobacter Designated Performance Tested Method by AOAC

3M Food Safety

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.
