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.
The researchers determined that probabilistic modeling could help food businesses capitalize on existing scientific data to map processing and formulation conditions for controlling non-proteolytic C. botulinum in refrigerated, processed foods of extended durability.
Oxford University researchers found that the expansion of dense, industrial chicken farming created conditions that enabled Campylobacter strains to spread, mix, and acquire traits that could improve their survival in poultry production environments.
A new study found high levels of multidrug resistance and biofilm formation among Enterococcus spp. isolated from retail meat, market workers, and consumers. Genetic similarities among E. faecalis and E. faecium isolates from different sources suggested potential cross-transmission at the food–human
interface, although the researchers emphasized that direct transmission was not established.
Hydrogen peroxide treatment, followed by catalase enzyme application to remove residual peroxide, significantly reduced Salmonella Typhimurium and Listeria monocytogenes on raw chicken wings while preserving the meat's overall color quality, although more research is needed on the effect on other organoleptic properties.
A new scientific review examines blue light-mediated photosensitization for antimicrobial intervention across various food sectors. The review notes the technology's promise as a nonthermal antimicrobial intervention for food safety and emphasizes the need for further studies to support scale-up across industry.
Transport cages are recognized as a potential source of cross-contamination in poultry slaughterhouses. The optimal washing water temperature and detergent concentration completely eliminated detectable Salmonella while greatly reducing indicator organisms. The identified parameters may improve food safety and operational efficiency.
A new hypothesis suggests Listeria monocytogenes persists by colonizing nutrient-rich voids left behind when Gram-negative bacterial biofilms disperse. If the theory is validated, the authors suggest shifting food safety strategies toward managing biofilm ecology and ecological succession, rather than focusing solely on pathogen detection.
