A molecular detection assay test kit for Listeria monocytogenes (Lm) available from 3M Food Safety has been approved by the Association Of Analytical Communities (AOAC) Performance Tested Methods (PTM) programme, which effectively means it is now equivalent or better than standard reference methods.

Achieving AOAC PTM status required a rigorous, independent laboratory examination of 3M’s molecular test method’s ability to accurately detect Lm in a variety of foods. Food samples analysed during the validation study 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).

“Third-party validations enable customers to meet internal and/or external requirements, and also provide them with added confidence in their testing,”​ says John David, global marketing supervisor with 3M Food Safety.

“We know our customers relied on having the original 3M molecular detection assays validated, so pursuing validations such as AOAC PTM for the next generation tests was always in our plan.”

The latest Lm assay is one of two test kits that have expanded 3M’s molecular detection system platform. The 3M molecular detection system is based on isothermal DNA amplification and bioluminescence detection technologies and designed around food processors’ needs for a real-time pathogen detection approach that’s faster and simpler while also more accurate.
