Phenomenex Inc.’s expanded “Design for PFAS” product portfolio features 15 additions to addresses a critical challenge in per- and polyfluoroalkyl (PFAS) analysis—false positives stemming from sporadic contamination and interferences.

The U.S. Department of Agriculture (USDA) has awarded $611,000 to University at Albany researchers to develop a rapid, portable, colorimetric Salmonella detection kit for food products.

As the platinum sponsor of the 2024 Food Safety Summit, NOMADX Holdings LLC has unveiled at the event an early access program for its portable NOMADX platform for onsite foodborne pathogen detection.

Thermo Fisher Scientific has introduced a new semi-quantitative analysis tool that simplifies inductively coupled plasma-optical emission spectroscopy (ICP-OES), enabling the identification of unknown samples.

FDA recently revealed results of a survey that found HPAI H5N1 genetic material in one in five retail milk samples; additional testing is required to understand the possible presence and risk of intact, infectious virus. Supported by other studies showing the efficacy of pasteurization against HPAI, FDA maintains its position that the U.S. milk supply is safe.

To address the spread of Highly Pathogenic Avian Influenza (HPAI) H5N1, the U.S. Department of Agriculture (USDA) has issued a federal order that requires testing of dairy cows for the virus, as well as mandatory reporting.

A Biosurveillance Intelligence, Surveillance, and Reconnaissance (BISR) system would address two mission-critical requirements for biosurveillance to detect and prevent outbreaks: rapid detection and predictive analysis.

The U.S. Food and Drug Administration (FDA) recently published testing results for per- and polyfluoroalkyl substances (PFAS) in foods collected as part of its Total Diet Study (TDS), and has provided an update on the agency’s activities to better understand and address PFAS in the U.S. food supply, including an updated analytical method to measure the chemicals. 

Researchers from Osaka Metropolitan University have achieved simultaneous detection of Escherichia coli and Staphylococcus aureus in real-world samples, on-site and within an hour, using a handheld electrochemical device.

Part 3 of this Food Safety Insights series on rapid testing asks food safety professionals whether the vast increase in outsourcing of testing to contract labs has made rapid methods less useful, or if the methods' ease of use and speed are still important for better management and decision-making.
