Testing & Analysis

A Purdue University research team has developed a new time-saving assay to detect Escherichia coli O157:H7 in ground beef.

Researchers have introduced a novel, thermal biosensor for real-time detection of Escherichia coli, demonstrating its ability to detect the pathogen in milk without sample preparation. The sensor would be easy to mass produce, and shows potential as a low-cost, rapid tool for onsite microbial indication.

ImagoAI Inc. has launched a new, affordable rapid mycotoxin test that provides results in 30 seconds for corn silage and corn mycotoxins.

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

Risk-based approaches for food allergens offer a path forward for both allergen management and precautionary allergen labeling decision-making. After many years of research, a clearer picture has emerged of the population-level, threshold-dose distributions for major food allergens using data generated in double-blind, placebo-controlled food challenge studies. If the food allergen management field is headed for a shift toward quantitative, risk-based management strategies, however, then several method considerations and important data gaps must be addressed.

The Food and Agriculture Organization of the United Nations (FAO) is planning to hold a workshop for government officials from low- and middle-income countries (LMICs) to learn about whole genome sequencing (WGS). Individuals interested in participating are invited to apply.

In this bonus episode of Food Safety Matters, we speak with Trevor Craig, Corporate Director of Technical Training and Consulting at Microbac Laboratories, about the dates on consumer food packaging, their impacts on shelf life and food safety and quality (FSQ), and the role Microbac can play in helping industry manage FSQ risks.
 

The Canadian Food Inspection Agency (CIFA) recently provided insight into how whole genome sequencing (WGS) and international data-sharing helped trace a 2020 multinational food safety outbreak of Listeria monocytogenes to enoki mushrooms, enabling countries to rapidly recall the affected products. 

A pervasive trend exists to take larger and more frequent samples to address microbial contamination. This trend has touched almonds and is expected to hit other nut products, which can be considered for aggregated sampling as a solution.

Two reports by the National Advisory Committee on Microbiological Criteria for Foods (NACMCF) have advised the U.S. Food and Drug Administration (FDA) and the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) on microbial testing of ready-to-eat (RTE) foods and the safety of recycled water in food production, respectively.
