3M Food Safety has announced that its 3M™ Molecular Detection Assay 2 – Listeria has been approved by the AOAC® Performance Tested MethodsSM program (Certification #111501). The approval certifies that this new second-generation test kit is equivalent or better than standard reference methods in the detection of Listeria spp. within a variety of food matrices and environmental surfaces.

Achieving AOAC PTM status required a rigorous, independent laboratory examination of 3M’s unique molecular test method’s ability to accurately detect Listeria spp. Food samples analyzed during the validation study included beef hot dogs, deli turkey, raw chicken leg pieces, raw chicken fillets, sealed concrete, plastic, stainless steel, melon, smoked salmon, romaine lettuce, queso fresco, vanilla ice cream, 4 percent milk fat cottage cheese and raw spinach.

“We’re pleased to be saving food processors and testing laboratories time in their efforts to detect Listeria in food,” said John David, global business manager with 3M Food Safety. “Having third-party validations reaffirms the robustness of the technology and further demonstrates our commitment to ensuring our products meet the highest performance standards.”

The latest Listeria assay is one of three test kits that were expanded on the innovative 3M™ Molecular Detection System platform. The 3M Molecular Detection System is designed around food processors’ needs for rapid pathogen detection and based on unique isothermal DNA amplification and bioluminescence detection technologies that provide a faster and simpler testing method with high accuracy. The new Listeria test kit now provides a reduced time-to-result – as little as 24 hours of enrichment – and features a streamlined workflow that is 30 percent faster than the first generation assay, originally launched with the platform in 2011

MicrobiologyMicrobiology is the study of microorganisms including protists, prokaryotes, fungi, and, often, viruses. Microorganisms are a useful research tool as genetic vectors and, in immunology, for antibiotic susceptibility testing, cellular biology and genetics. Microorganisms commonly grow readily in incubators with microbial culture media; this can contain chromogenic supplements to differentiate between cell lines. Estimate your culture’s density of microorganisms with colony counters, or screen and select colonies for desirable clones with automated colony pickers. Additionally, equipment is available to monitor environments for the presence of microbes and identify with microbial identification instruments.

Useful features of analyzers such as BOD and COD include portability, easy calibration, automation and sensitivity.  Environmental test kits for pH, water, moisture, etc, should be accurate, sensitive, reliable, fast and easy to use.Food and Beverage AnalyzersFood and Beverage Analyzers are commonly used to provide information about the chemical composition, structure and physical properties of food materials.Food and Beverage ProcessingFood and Beverage Processing involves the preparation of food products for further analysis. Typical instrumentation includes blanchers, color sorters, cookers, grinders, and refrigeration. These are used to replicate the processes commonly used in the commercial preparation of food and beverages.Molecular BiologyMolecular biology is the branch of biology that focuses on the molecular mechanisms that underlie cellular functions. It involves studying DNA, RNA, and proteins to understand gene expression, replication, and regulation. Molecular biology is fundamental to biotechnology, medicine, and genetic research.

Contamination with a variety of pathogens can be prevented with adequate temperature control, hygiene and labeling. Food samples can be tested using GC/MS, HPLC, SPE, and qPCR to ensure their adherence to regulations.BioluminescenceDNA AmplificationDNA Amplification is a technique used to amplify a single or multiple copies of DNA or mRNA by orders of magnitude. The most common method employed is PCR, but other options exist that eliminate the need for thermocycling.Food TestingFood testing refers to a variety experiments including PCR, mass spectrometry, processing, QuEChERS, analyzing and Kjeldahl.Pathogen DetectionPathogen detection is the process of identifying harmful microorganisms, including bacteria, viruses, and fungi, that can cause diseases. Accurate pathogen detection is critical for food safety, public health, and clinical diagnostics.
