Two complimentary studies funded by the Center for Produce Safety (CPS) are using genomic sequencing technology to examine how storage conditions affect microbial growth on pears, with a focus on Listeria monocytogenes.

ColloidTek’s Collo Analyzer is a new method for real-time liquid process quality monitoring. Based on EMF sensors and machine learning, the technology detects various contaminants and identifies potential risks in liquid processing with a single real-time measurement and instant, inline analysis.

Ongoing debates about the use of rapid test methods in food safety have led to the rise of the question: Has the vast increase in outsourcing testing to contract labs made rapid methods less useful, or is the ease of use and speed of the methods still important (if not essential) for better management and decision-making in food safety? Food Safety Insights asks food safety professionals their opinions on this question.

Sampling is part of a process that has two functions. It can be used to sample a process during operations or to sample the output of a process, such as a product lot. During sampling, the measurand (the object being measured) must be properly selected, properly transported to a location where the object or objects will be analyzed, and the results must be reported to the appropriate individuals. This article covers the systematic development of a sampling plan.

A tool developed by European Food Safety Authority (EFSA) scientists allows for the screening of proteins in foods that trigger reactions in celiac disease patients, ensuring greater food safety. The tool could potentially be applied in a range of food safety areas.

Through a newly forged partnership, Oxford Nanopore’s sequencing devices and kits, combined with WeNou’s expertise, will be leveraged to develop a validated food authenticity rapid test that meets industry standards.

The U.S. Food and Drug Administration (FDA) has updated the chapter on Cronobacter of the Bacteriological Analytical Manual.

In this bonus episode of Food Safety Matters, we speak with two food safety experts from MilliporeSigma—Justyce Jedlicka, Food and Beverage Regulatory Liaison in North America, and Andrew Lienau, Food Regulatory and Validation Expert—to discuss the threat that Cronobacter poses to food safety and public health, and how testing for this complex pathogen is crucial to controlling its impact.

The European Food Safety Authority (EFSA) has introduced TKPlate, a new platform that can model and predict the toxicity and toxicokinetics of chemicals used in foods, which will help reduce the amount of animal testing used in food safety assessments.

The World Health Organization (WHO) recently published a three-part guide describing how whole genome sequencing (WGS) can be used as a tool to strengthen foodborne illness surveillance and response.
