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.

Salmonella infection is one of the most commonly reported causes of foodborne illness, resulting in over 80 million cases of foodborne salmonellosis each year globally.

Researchers from the Singapore Food Agency’s National Center for Food Science and the National University of Singapore have developed a real-time polymerase chain reaction (PCR) approach for the detection of viable Salmonella Enteritidis contamination in shell eggs, which would accelerate the traditional Salmonella testing process if integrated.

bioMérieux’s new GENE-UP® ENVIROPRO™ detects both Salmonella and Listeria from environmental swabbing, including PCR confirmation.

A recent study suggests that the cold foods supply chain is the optimal environment for the COVID-19 virus to spread over long distances. The study explores various prevention and testing methods that could be used to mitigate the pathogen’s spread through cold-chain foods.
