Blue light could cut food poisoning from raw chicken

Food safety is a major public health concern across the globe, with poultry products frequently cited as a primary source of foodborne illness. Campylobacter bacteria are responsible for the vast majority of these infections, leading to severe gastrointestinal distress and, in some cases, long-term health complications for affected individuals.

Researchers at the University of Reading have turned their attention to novel decontamination methods to tackle this persistent issue. Their recent findings suggest that deploying low-power blue light could offer an effective and chemical-free way to target and reduce bacterial loads on raw chicken surfaces before preparation and consumption.

The implications of this research are substantial for both consumer health and the broader economy. Within the United Kingdom, Campylobacter infections affect hundreds of thousands of people each year. The cumulative financial burden of healthcare treatment, missed workdays, and reduced productivity climbs to an estimated £700 million annually.

Implementing a straightforward light-based intervention could transform processing plants and commercial kitchens. Unlike harsh chemical washes that may alter the taste or texture of the meat, targeted light wavelengths work by disrupting bacterial cellular processes without compromising the quality of the food product.

As the scientific team continues to refine this technology, industry stakeholders are closely monitoring its potential rollout. Moving forward, large-scale testing and regulatory approvals will be necessary to integrate blue light treatments into standard poultry processing supply chains safely and effectively.
