Can Blue Light Keep Us From Getting Colds, Flu, COVID and More?
The facts are Blue Light in a specific SAFE wavelength kills Salmonella and Listeria. It has been written that the Salmonella Peanut Butter Call Back could cost the company $125 Million dollars. Did you know that there is now a SAFE LED Blue light that when used in food processing industries could cut down on the Salmonella and Listeria problems in the food industry. The question is why they are not taking advantage of the years and years of research from leading professors at some of the top schools in the country Harvard, Wisconsin, San Diego State that says Blue Light can deactivate Listeria and Salmonella. They have proved many times over that Blue Light from 405nm to 470nm kills both Salmonella and Listeria.
Don’t Take My Word For It! This is from an article in the Scientific World Journal.
Despite enormous investments in public health research, bacterial pathogens transmitted in food, water, and from other environmental sources remain a major cause of illness in both the developed and developing world. Examples of such ubiquitous pathogens include enteric Gram-negative bacteria such as Salmonella, Escherichia, and Shigella which continue to cause significant diarrhea infections worldwide [1]. The foodborne pathogen Listeria monocytogenes also, has significant impact on health statistics through its propensity for causing serious illness in the immunocompromised [2]. Actinobacteria from the Mycobacterium genus are also a major cause of human morbidity and mortality and pathogens from the Mycobacterium tuberculosis complex such as M. bovis and M. tuberculosis remain amongst the most serious causes of infective disease worldwide [3].
Simple Food Grade Blue Light like this around the plant could help keep their products from getting Salmonella and Listeria on top of that it will help keep their employees healthy because the Blue Light also kills a wide range of other bacteria and viruses including MRSA, Staff, Strep, COVID, Colds and Viruses and more.

Abstract
Background and objective: Emerging evidence suggests that blue light can photo-inactivate some bacteria of clinical importance. Consequently, we tested the hypothesis that 470 nm light can suppress growth of two recalcitrant bacteria, MRSA and Salmonella.
Materials and methods: We plated 5 × 106 and 7 × 106 CFU/ml USA300 strain of MRSA and 1 × 106 CFU/ml of Salmonella enterica serovars Typhimurium and Heidelberg. Plates were irradiated with 55, 110, 165 and 220 J/cm2 of blue light, incubated at 37°C for 24 hours and colony counts determined.
Results: Compared with controls, blue light irradiation produced a significant dose-dependent reduction in the number of colonies formed by each bacterial strain (P < 0.001). Irradiation of 5 × 106 and 7 × 106 CFU/ml MRSA with 55 J/cm2 produced 92% (4.6 × 106 CFU/ml) and 86% (6 × 106 CFU/ml) inactivation respectively, while 110 and 220 J/cm2 suppressed each MRSA density 100%. Irradiation of Salmonella Typhimurium with 55 and 110 J/cm2 suppressed bacterial growth 31% (3.1 × 105 CFU/ml) and 93% (9.3 × 105 CFU/ml) respectively; while Salmonella Heidelberg was inhibited 11% (1.1 × 105 CFU/ml) and 84% (8.4 × 105 CFU/ml) respectively by the two fluences. Complete inactivation of each Salmonella strain was achieved using 165 or 220 J/cm2 .
Conclusion: The observed inhibition of Gram-positive (MRSA) and Gram-negative (Salmonella) bacteria suggests the versatility of blue light in bacteria eradication, making it a viable intervention strategy for decontamination of food and environments that harbor such bacteria.
