The approval certifies the test kit is equivalent or better than standard reference methods.
Samples analyzed in 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 environmental surfaces (plastic, stainless steel, concrete).
John David, global marketing supervisor with 3M Food Safety, said validations enable customers to meet internal and/or external requirements and added confidence in their testing,
“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.”
FQN spoke to 3M when it launched L.monocytogenes and Listeria assays last month.
The 3M Molecular Detection System is based on isothermal DNA amplification and bioluminescence detection technologies.
It provides a faster time-to-result –24 hours of enrichment – and features a streamlined workflow that is 30% faster than first generation assay.
