The project will evaluate the resulting assay's potential applications in relevant food matrices, including chicken, turkey, pork, and beef, with the broader objective of improving the identification of Salmonella strains associated with human illness and outbreaks.
After further optimization and validation, the approach could possibly offer an alternative to conventional culture-based screening methods that typically require three to five days. The bacteriophage amplification strategy, which was tested against Salmonella on chicken meat, could be adapted to detect other viable foodborne bacteria.
Developed in partnership with USDA-FSIS, the assay detects Salmonella spp. while targeting up to three proprietary genetic markers associated with pathogenicity, supporting surveillance and research into risk-based approaches to Salmonella control.
In-house quality control teams and third-party laboratories can use the GENE-UP PROBIOTIC SPECIES ID assay to identify 18 commonly used probiotic species in 90 minutes or less.
According to the company, the GENE-UP TYPER SLM assay specifically targets S. enterica, the subspecies most commonly associated with human salmonellosis and foodborne illness.
Allergen Alert is a portable device that automates the full laboratory analytical process in a “mini lab” so that consumers and foodservice professionals alike can detect the presence of allergens or gluten in a meal, onsite and in minutes, ensuring food safety for those with food allergies and celiac disease.
Two research projects are investigating several novel techniques for detecting hepatitis A virus that eliminate false positives produced by inactivated, non-infectious RNA fragments—an issue that limits the usefulness of existing methods for indicating actual food safety risk.
This episode of Food Safety Five discusses two scientific developments that could help address the risk posed by Cronobacter in powdered infant formula: an AI-powered analysis of genetic data for C. sakazakii, providing new insight into why it persists in low-moisture foods, and the development of a promising new assay.
Researchers in China have developed a new onsite rapid test, based in fluorescence RNA-targeted isothermal amplification assay (SAT) technology, that can quickly detect and identify Cronobacter species in powdered infant formula. It offers significantly greater sensitivity and much more rapid results than polymerase chain reaction (PCR), without producing false positives.
The new XP-Design Assay Salmonella Serotyping Solution from Bio-Rad enables rapid detection and precise characterization of Salmonella in food and environmental samples.
