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.

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.

The U.S. Department of Agriculture has launched a new exploratory sampling program for antibiotic residues in cattle that are claimed to be raised without antibiotics. 

A recent study conducted by researchers from the University of Illinois Urbana-Champaign concluded that, when sampling powdered infant formula for Cronobacter contamination, sampling with stratification may be more powerful than random sampling, and that taking more samples, even if smaller, increases the ability to detect contamination.

The U.S. Food and Drug Administration (FDA) recently released the findings of a sampling assignment that collected and tested ready-to-eat (RTE) dips and spreads with the aim of determining the presence of Listeria monocytogenes and Salmonella.

The UK Food Standards Agency (FSA) has published a Post-Implementation Review of the 2013 Food Safety Sampling and Qualifications Regulations (S&Q Regulations), which is now available for public comment.

Some will argue that more sensitive methods are needed to drive change. This is a reasonable argument, but it misses the underlying problem of defining the mission before implementing a sampling and testing program.

The U.S. Department of Agriculture’s Food Safety and Inspection Service (USDA’s FSIS) has notified constituents that establishments wishing to adopt the cloth sampling method (i.e., manual sampling device or continuous sampling device) for Shiga Toxin-producing Escherichia coli (STEC) testing of raw beef products no longer require a “No Objection Letter” (NOL) from FSIS.
