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 article discusses the results of a 2024 follow-up survey to a 2019 workshop on the food industry's use of whole genome sequencing (WGS), the benefits and challenges of this technology, and necessary advancements for its continued acceptance and effective use in ensuring food safety.

A UK-based study, led by Quadram Institute researchers, underscores the limitations of traditional enumeration methods for foodborne pathogen surveillance and highlights the need for whole genome sequencing (WGS) to better assess the food safety risk posed by commensal or opportunistic Escherichia coli lineages.

A letter sent to FDA urges the agency to immediately withdraw its approval of Carbadox, a carcinogenic swine feed additive. FDA’s proposal to withdraw Carbadox approvals has been pending for two years, during which time there has not been an approved method for detecting Carbadox residue in pork. 

Bio-Rad Laboratories Inc. has announced that its iQ-Check Enterobacteriaceae Kit has received MicroVal certification for the real-time PCR detection of Enterobacteriaceae in infant formula, infant cereal with and without probiotics, and related ingredients.

LGC Standards has expanded its portfolio of Dr. Ehrenstorfer PFAS testing solutions with new 13C-labeled reference materials developed for EPA Method 1633.

Polycyclic aromatic hydrocarbons (PAHs) are carcinogenic compounds formed during cooking. A new Seoul Tech study has demonstrated the effectiveness of a streamlined analytical method to detect PAHs, which holds distinct advantages over conventional techniques.

A new study led by the University of South Australia offers a promising real-time mycotoxin detection method for the food industry that is based in artificial intelligence (AI) technology, and overcomes some of the limitations of traditional detection methods.

This article discusses the development of low-cost, user-friendly biosensors to improve food safety in produce.

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.
