The Petrifilm Lactic Acid Bacteria Count Plate is the first commercial method of its kind to win validation from a third-party scientific organization, the AOAC Research Institute.

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.

DuPont BAX System X5 PCR Assay for Genus Listeria

The AOAC Research Institute approved a method extension of Performance Test Method #030502 to include the DuPont BAX System X5 PCR Assay for Genus Listeria. The assay has been validated as a reliable method for detecting the pathogen in frankfurters, smoked salmon, spinach, and cheese, as well as from environmental surfaces. Using the system, automated PCR-based DNA amplification and automatic pathogen detection can be conducted on 32 samples simultaneously within a smaller and more lightweight unit. The system is also validated by AOAC-RI for detecting Salmonella and Listeria monocytogenes in good and environmental samples.
