University of California, Riverside researchers have identified key chemical reactions that occur when UV light is used to break down PFAS “forever chemicals” in water, which could inform the development and optimization of PFAS treatment technologies, or even more degradable fluorinated compounds.
Based on an analysis of 2.8 million samples collected in 41 countries over 25 years, the global pooled prevalence of foodborne and zoonotic bacteria, viruses, and parasites was 15 percent.
A total of 68.8 percent of vendors were noncompliant with Food Safety and Standards Authority of India (FSSAI) regulatory requirements. Only 21.8 percent of participating vendors reported having received any food safety training.
Mycotoxins, PAHs, and other contaminants were also detected. The researchers concluded that plant-based protein supplements may contain chemical contaminants from environmental exposure, agricultural practices, and processing. They called for systematic monitoring, improved controls, and optimization of processing conditions.
Acrylamide is a harmful contaminant that forms during thermal processing. An analysis of 17 years of EU RASFF data showed that UPFs accounted for 85 percent of related notifications. Cereals, baked goods, and potato chips were most frequently implicated.
According to the researchers, 1,222 FCCs are already known to be hazardous to human health, and more than 13,000 lack sufficient data to determine safety. Until adequate data become available, they proposed grouping FCCs based on chemical structure to help identify substances that may pose similar hazards.
The researchers analyzed cost and sequencing-volume data from 23 FDA and FDA partner GenomeTrakr laboratories. Findings suggested that WGS-based genomic surveillance is a cost-effective public health investment.
Researchers observed inflammatory responses, gut barrier damage, and immune effects relevant to allergy development in experiments with two emulsifiers, soy lecithin and DATEM. Study author Dr. Cezmi Akdis said the findings support a more comprehensive framework for evaluating food additive safety.
Longer application times, shorter nozzle distances, and spray patterns that deliver sufficient physical force to surfaces may contribute to improved microbial reduction. Sanitizer efficacy experiments could misrepresent real-world sanitation outcomes when shear stress and application time are not considered.
Potential uses include pathogen and chemical hazard detection, food fraud identification, outbreak surveillance, risk forecasting, and regulatory decision-making. Barriers to wider adoption remain, such as data quantity, quality, and accessibility; confidentiality; and transparency.
