Polycyclic aromatic hydrocarbons (PAHs) are potentially carcinogenic compounds formed during high-heat cooking. An emerging testing method known as QuEChERS—which stands for “Quick, Easy, Cheap, Effective, Rugged, and Safe”—is designed to overcome the limitations of conventional PAH tests.

In this episode of Food Safety Matters, we speak to water activity specialist and researcher Dr. Brady Carter about the importance of understanding water activity for shelf-life prediction, enhancing food safety and quality, and improving food system sustainability.

The company says this trademark reflects its advancement of diagnostic technologies that enhance food protection, public health, animal health, and environmental monitoring.

The guidance was developed to help manufacturers and laboratories in the design, conduct, evaluation, and reporting of Protein Efficiency Ratio (PER) studies.

This article discusses the problem of false positive results when using propidium monoazide (PMA) in PCR testing for food safety. 

The findings, based on a novel approach and published in Nature Health, suggest that traditional chemical safety assessments may overlook combined exposures and real-life environmental conditions. Transcriptomic analysis implicated a non-genotoxic mode of action by which pesticides interfere with normal cell function and identity processes.

This article reviews why testing for Salmonella is important, the challenges encountered when testing for Salmonella (specifically when using FDA's Bacteriological Analytical Manual Chapter 5 guidelines), and how to evaluate if your testing laboratory is providing reliable testing results. 

The list includes kits validated for Salmonella, Campylobacter, Listeria, and Escherichia coli.

This episode of Food Safety Five discusses new academic publications exploring the limitations of a “zero-risk” approach to food safety and evaluating the limited benefits and trade-offs associated with intensified microbiological sampling.

The third Science Meets Policy conference will take place September 2–3 in Rome, Italy, focused on helping EU competent authorities and industry members effectively implement new WGS data-sharing requirements for foodborne pathogens.
