This webinar was originally hosted by Select Science on May 20, 2021. Jørgensen highlights how this method can be applied to primary and secondary enrichments, as well as for the confirmation of isolates, and was especially important in analyzing products that were co-contaminated with other serovars where the presence of Salmonella Enteritidis was realized only as a result of the PCR. Frieda Jørgensen, Senior Scientist, Health Protection England, outlines the current investigation of Salmonella Enteritidis, sharing how the Thermo Scientific™ RapidFinder™ Salmonella multiplex PCR test enables rapid detection of contaminated products. A quick and easy culture-based method for detection of Salmonella species has been validated for the broadest range of food, animal feed, and environmental samples, and is ready to slot into standard laboratory workflows.Ī serotype-specific PCR method for detecting Salmonella spp. Streamlined Salmonella testing drives efficiencies, enables flexibility, and solves problemsĮxtended validation of the Thermo Scientific Salmonella Precis Method simplifies workflows and encompasses challenging food matrices. The SureTect Salmonella Species PCR Assay has been granted AOAC Official Method Analysis (OMA) status. Latest validation offers food laboratories additional layer of confidence when testing for Salmonella Thermo Fisher Scientific’s test is the first validated multiplex PCR workflow for the most common – and dangerous – Salmonella serotypes offers a multi-target approach that can cuts costs, reduces delays, and increases confidence for poultry and pork producers.

In this special Spotlight, Daniele Sohier takes a deep dive into Salmonella, its serotypes and prevalence, and how to keep it out of your facilities, your products, and your customers.įaster path to actionable answers for poultry producers That’s why we’re taking you back to basics with our five top tips for Salmonella prevention, based on what we’ve learnt from recent outbreaks.ĭespite our understanding of how Salmonella proliferate in our food manufacturing processes, the bacteria still cause millions of illnesses and hundreds of deaths every year. But with so much on the line, from public health to brand reputation, we can never be too careful. We know that food testing laboratories take their responsibility to screen their products for potentially dangerous pathogens seriously. Yet despite its well-documented benefits, many laboratories have been put off by the perception that PCR is expensive to adopt and complex to conduct.įood for thought: Danièle takes Salmonella prevention back to basics with five lessons from recent outbreaks Thanks to its speed and accuracy, polymerase chain reaction (PCR) testing is changing the face of Salmonella screening. Other affected foods include raw meat, powdered infant formula, milk and dairy products, fish, shrimp, salad dressing, cake mixes and chocolate.įood for thought: Danièle explains why PCR-based Salmonella screening makes the best economic sense Low cell numbers can be highly infectious, especially in high fat foods where the microorganism can escape the gastric acidity and be released in the intestine through bile mediated dispersion of the lipids.ĭespite the general perception that chicken and egg products are the primary source of Salmonella infections, many outbreaks in recent years have been associated with tomatoes, peanut butter, and vegetable sprouts. The ingestion of 1-10 cells can constitute a human infectious dose. An estimated one million cases occur annually in the United States of these, approximately 35,000 are laboratory-confirmed cases reported to Centers for Disease Control and Prevention. Salmonellosis is the most frequently reported cause of foodborne illness. There are over 2,500 serovars of Salmonella, which are characterized according to somatic (O) and flagellar (H) antigens. Salmonella are Gram-negative, non-spore forming rods. The genus Salmonella belongs to the family Enterobacteriaceae.
