A recent study has demonstrated that current sampling and testing methods for Campylobacter may overlook epidemiologically-important strains. The researchers suggest using optimized culture methods and analyzing multiple isolates per sample.

Torrey Pines Scientific has unveiled its EchoTherm™ Model IC50—a Peltier-driven, chilling/heating dry bath with exact sample temperature control.

The U.S. Food and Drug Administration (FDA) has released a draft guidance for industry on collecting samples for testing seafood products subject to Detention Without Physical Examination (DWPE).

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.

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 protocol for the collection of honey reference samples for the creation of authenticity databases has been developed by the UK Government. Honey is one of the food commodities most subject to food fraud.

On November 1, 2023, the U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) will begin a one-year sampling program of domestic beef, pork, and Siluriformes fish (commonly referred to as catfish) to determine levels of dioxins and dioxin-like compounds.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has released a notice informing agency inspection program personnel about the continuation of and changes to the Raw Pork Products Sampling Program.

The International Dairy Federation (IDF) recently published a new document to help the dairy industry conduct in-process product sampling that produces accurate and actionable microbiological data. 

Non-cultivable foodborne pathogens, such as enteric viruses and protozoan parasites like Cyclospora, present unique challenges in our food system due to significant limitations in sampling and detection. This article covers the methodological drawbacks of current methods related to interpretation of results and public health risk, while offering alternative food safety management principles to address the prevalence of these pathogens in food.
