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.

The new test was developed in response to customer engagement and a desire to work with food processors to protect the world’s food supply, says 3M Food Safety.

(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.
