Combating foodborne illness is one of, if not the most important aspect of food processing and manufacturing. Annually, approximately 48 million people in the United States suffer from some sort of food related illness (CDC, 2018). Due to this, it is imperative that new and innovative ways to combat such issues are researched and validated to increase food safety. Recently, photodynamic inactivation of pathogens has come to the attention of the food industry. While irradiance with ultraviolet light had been researched and validated for use in the food industry, it has been known to cause health problems to humans under prolonged exposures and carries with it a negative connotation in the view of the consumer. Light emitting diodes (LEDs) producing ultra-high irradiance (UHI) blue light in the range of 400nm-460nm are a new approach for inactivation of bacterial pathogens. These LEDs are from the visible spectrum which is safe for humans and have the potential to reduce or eliminate pathogen contaminations on food products, food contact surfaces, and can aid in biofilm deterioration. This research aims to test the antimicrobial potential of UHI blue LEDs (405 and 460nm) against foodborne pathogens commonly associated with low-moisture foods (LMFs), Salmonella spp. and E. coli O157:H7, using paprika powder as a model LMF system and commonly found food contact surface materials in dry food processing facilities. The suitability of Enterococcus faecium as an appropriate Salmonella surrogate for the validation of UHI blue light treatments in LMFs was also evaluated. Throughout this research, bacterial reductions of >7 logs were noted in both paprika powder and metal food contact surfaces indicating that blue light LEDs have great potential for combating bacterial contamination and increasing the safety of food supply chains. Inactivation kinetics indicated that E. faecium is a suitable Salmonella surrogate for the validation of on-site process interventions using UHI blue light.
