3M Food Safety’s 3M Molecular Detection Assay Listeria monocytogenes has been approved by the AOAC Performance Tested Methods (PTM) program.
The approval certifies that the test kit, which helps food processors and other parties quickly and accurately detect Listeria monocytogenes, is now considered equivalent or better than standard reference methods for select food matrices by the international organization.
The assay provides rapid results in as little as 24 hours of enrichment – days faster than the standard methods.
The food samples analyzed during the validation study include full fat cottage cheese, chocolate milk, beef hot dogs, deli turkey, cold smoked salmon, bagged raw spinach, romaine lettuce and whole cantaloupe. Testing also covered environmental surfaces including stainless steel and concrete.
Meanwhile, the 3M Molecular Detection Assay Listeria species has received a matrix extension by the AOAC PTM program.
The test kit has received the PTM extension for the following matrices: full fat cottage cheese, beef hot dogs, deli turkey, cold cooked salmon, bagged raw spinach, whole cantaloupe, as well as environmental surfaces including stainless steel and concrete.
The 3M Molecular Detection System is based on an isothermal deoxyribonucleic acid amplification and bioluminescence detection technologies.
It is designed to provide a real-time pathogen detection approach that is reportedly faster and simpler while also more accurate.
The company also has AOAC Official Method of Analysis or OMA status for its Salmonella assay and both AOAC PTM and NF Validation by certifying body AFNOR Certification for its Salmonella and E.coli O157 (including H7) assays, in addition to certifications from government and regulatory organizations in other countries around the world.
