Testing & Analysis

RSS

McMaster University researchers have developed a rapid, inexpensive test for Salmonella contamination in poultry and other food. The test provides accurate results in an hour or less without the need for accessories or a power source.

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.

A new guidance document from ILSI Europe on the existing approaches for analyzing Non-Intentionally Added Substances (NIAS) from different food contact materials has been released. 

PathogenDx has expanded the reach of its patented multiplexed molecular testing technology—Dynamic Dimensional Detection (“D3 Array™”)—beyond the cannabis and hemp sectors, to the agriculture and food sectors.

Researchers from Pusan National University in Busan, South Korea have developed a polydiacetylene-based sensor that offers rapid visual detection of biogenic amines released from spoiled food, indicating when products have gone bad.

The Association of Official Agricultural Chemists Africa Section (AOAC Africa) has established a partnership with the African Organization for Standardization (ARSO) to develop analytical methods for the continent’s most widely consumed foods. 

Hanna Instruments Inc. has released its new Advanced Benchtop Meter Series, which includes three new models for testing pH, conductivity, and dissolved oxygen.

In this episode of Food Safety Matters, we talk with Martin Wiedmann, Ph.D., D.V.M., the Gellert Family Professor in Food Safety and Food Science at Cornell University, about his research on Listeria and Salmonella, his work to strengthen foodborne illness surveillance and response, his use of whole genome sequencing (WGS), and other topics.

Using whole genome sequencing (WGS), the U.S. Centers for Disease Control and Prevention were able to link a persistent, drug-resistant strain of Escherichia coli O157:H7 to multiple sources for various foodborne illness outbreaks.

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