Garlic carries a distinct bacterial signature reflective of the soil in which it was grown, enabling geographic identification based on microbial composition. A novel method using microbiome data and AI analysis potentially offers a low-cost authentication technique.

This article takes a deeper look at air quality standards and monitoring for food processing facilities.

The low-cost approach enables simultaneous detection of multiple foodborne pathogens and spoilage microorganisms in a shorter timeframe than traditional detection methods, without requiring advanced technical training. 

The platform uses a DNAzyme-crosslinked hydrogel that produces a visible color change when E. coli is present, enabling equipment-free, point-of-use detection. It successfully detected E. coli in a range of foods, even when other pathogens were present.

The Infant Formula Safety Modernization Act includes provisions about expanded pathogen testing requirements and compulsory environmental monitoring for infant formula manufacturers, among other mandates.

Marking the country’s first use of whole genome sequencing (WGS) in an active foodborne illness outbreak investigation, advanced genomics enabled Moldovan authorities to rapidly solve and respond to a salmonellosis outbreak that sickened more than 140 people in 2025.

The researchers positioned the machine learning model as a low-cost complement to traditional testing workflows, helping dairy processors enhance food safety while targeting laboratory resources.

This episode of Food Safety Five discusses expert perspectives on the Healthy Florida First food contaminant testing program, including information gaps about the testing and risk assessment methodology and why this missing information matters.

The scientists will isolate and identify pathogens like Salmonella enterica and Listeria monocytogenes from Pennsylvania wastewater using whole genome sequencing (WGS), then work with the State Department of Health to connect isolates to foodborne illness outbreaks.

The researchers conducted environmental sampling throughout a controlled environment agriculture (CEA) operation and tested swabs for L. monocytogenes. Boot covers proved to be a useful tool for evaluating the effectiveness of cleaning and sanitation.
