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.

Supporting routine laboratory testing, the GENESYS G5 series features an expanded software ecosystem with optional application-specific packages, including guided workflows and preconfigured methods intended to reduce setup time and improve consistency.

The platform was developed to address limitations of earlier DNA barcoding methods by using species-targeted genomic approaches, authenticated reference materials, and analytical systems designed specifically for commercial botanical products.

ByHeart-commissioned research shows the currently accepted “gold standard” for Clostridium botulinum detection in powdered formula, SRC enumeration, may fail to catch contamination. It is used by many formula brands, including Nara Organics, another company linked to an infant botulism outbreak. Following this finding, third-party IEH Labs developed a novel detection method.

As the agency continues to delay enforcement of Salmonella verification testing for not-ready-to-eat, breaded and stuffed chicken products, Consumer Reports is asking for evidence to support USDA-FSIS’ assertion that currently available test methods are not suitable, which contradicts the agency’s previous stance.

Although the levels of gluten in analyzed samples fell below EU limits, the results from conventional ELISA tests differed from those of a new, more sensitive method. Combining established rapid testing methods with advanced mass spectrometry techniques could potentially improve future detection capabilities.

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 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.
