Food microbiology testing methods for Listeria species

Thermo Fisher Scientific
9 Dec 2025

Listeriosis is a foodborne illness commonly caused by Listeria monocytogenes. It is a relatively rare but serious infection and can lead to severe symptoms, especially among vulnerable populations such as pregnant women, newborns, the elderly, and individuals with weakened immune systems.

Explore this resource as it highlights how the Thermo Scientific™ SureTect™ Listeria Species PCR Assay provides fast, reliable detection across difficult food matrices to strengthen food safety and contamination response. It also demonstrates how established reference methods (ISO 11290‑1:2017, FDA BAM Chapter 10, USDA FSIS MLG 8.15) together with Thermo Scientific™ Listeria Precis™ chromogenic media improve confirmation workflows, support regulatory compliance, and simplify comprehensive Listeria control.

PCR and Thermal CyclingPolymerase chain reaction (PCR) kits and thermal cyclers are used for the in vitro amplification of DNA permitting subsequent analysis and experimental procedures. Explore a range of high-quality polymerase, primers and nucleotides or simplify your workflow with a PCR mastermix. Find reverse transcription PCR (RT-PCR) and cDNA synthesis kits for RNA products and libraries. Quantitatively measure the amplification of DNA with real-time PCR (qPCR) and droplet digital PCR (ddPCR) kits and systems, and discover automated PCR setup solutions to increase throughput. Alternative DNA amplification methods also include recombinase polymerase amplification (RPA) kits. Find the best PCR kits and thermal cyclers and purification equipment in our peer-reviewed product directory: compare products, check customer reviews and receive pricing direct from manufacturers.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.
