Proactive Listeria testing can save millions in recall costs. Learn how validated PCR diagnostics, rapid environmental monitoring, and data-driven insights help food brands prevent contamination, ensure compliance, and protect consumer trust.

New research has demonstrated a low overall prevalence of Campylobacter on retail chicken meat; however, recovered C. jejuni strains did not match known poultry-associated genotypes, suggesting the need for sensitive detection methods and expanded genomic surveillance.

Bio-Rad Laboratories’ new EZ-Check Salmonella Kit is a rapid, polymerase chain reaction (PCR)-based detection method for Salmonella in food and environmental matrices.

Efforts are underway to create a patchwork of new state-specific extended producer responsibility (EPR) and stewardship programs, recycling requirements, and minimum post-consumer recycled (PCR) content requirements that apply to packaging materials used for food and beverage products. Entities across the entire food and beverage supply chain may be implicated and need to be prepared for compliance. 

A Center for Produce Safety-funded proof-of-concept study is exploring a novel, high-throughput capture and concentration method for hepatitis A virus in fruit wash water, which uses magnets and hydrogel nanoparticles. It could be added to existing FDA and ISO digital PCR assay workflows, potentially reducing false positives.

The new GENE-UP® TYPER solution from bioMérieux combines a PCR pathogen detection assay with a machine learning-based web application, facilitating root cause analysis of contamination incidents in the food industry.

Combining multiplex PCR and DNA barcoding, Chapman University researchers successfully detected fraudulent adulteration in half of ginseng supplement samples tested. With 28 percent of samples still unable to be identified, the researchers call for future studies combining DNA- and chemical-based testing methods. 

In light of a recent investigation that found nearly half of honey imported to the EU is adulterated, UK researchers have demonstrated the promise of two innovative techniques—DNA barcoding and spatial offset Raman Spectroscopy—for detecting sugar adulterants in honey.

Primerdesign recently launched its new genesig® Easy_oys Detection Kit for Norovirus in oysters, a quantitative polymerase chain reaction (qPCR) assay capable of producing results onsite in as little as four hours.

Researchers in Japan have developed a novel method to accurately detect Escherichia albertii, which is an emerging zoonotic foodborne pathogen with increasing relevance in the country, and is also often misidentified as E. coli.
