Independent Study Finds Molecular Salmonella Test Found to be Hours Faster than Current Method

3M Food Safety today announced the results of a scientific study conducted by a third party ISO/IEC 17025 accredited laboratory. Cost and time associated with performing each platform’s protocol was modeled (evaluated) by comparing workflows.

The research found that the 3M™ Molecular Detection Assay 2 – Salmonella test saved significant hours and cost versus three other common pathogen detection platforms included in the study.

For each of the four pathogen detection platforms, a total of 96 samples of ground poultry were evaluated in duplicate, resulting in 192 detection method tests per platform, for a total of 768 results. Time was measured on the aggregate and according to the following parts of the detection protocol: sample preparation; instrument and software set up; sample lysis/capture; and assay setup.

The study focuses largely on speed because turnaround time significantly affects food production and testing, particularly when a producer’s goods are perishable or in high demand. While the introduction of any rapid microbiology method should have a positive impact, there are still distinctions between each method.
