Salmonella Is Killed By SAFE Blue Light
According to the CDC
This is what I just read in the news today Monday October 26, 2020. Very sad news. We have been working with grocery stores and meat packing people to help keep that from happening. The facts are SAFE Blue Light in a wavelength of 405-430nm will kill listeria and salmonella.
The antimicrobial properties of light is an area of increasing interest. This study investigates the sensitivity of the signiﬁcant foodborne pathogen Listeria monocytogenes to selected wave- lengths of visible light. Results demonstrate that exposure to wavelength region 400–450 nm, at sufﬁciently high dose levels (750 J cm)2), induced complete inactivation of a 5 log10 popu- lation. Exposure to wavelengths longer than 450 nm did not cause signiﬁcant inactivation. Analysis of 10 nm bandwidths between 400 and 450 nm conﬁrmed 405(±5) nm light to be most effective for the inactivation of L. monocytogenes, with a lesser bacteri- cidal effect also evident at other wavelengths between 400 and 440 nm……
SWP and LWP ﬁlters were selected to assess the wavelength sensitivity of L. monocytogenes to inactivation within the range 400–500 nm. Figure 3 shows the effect of different light wavelength ranges on suspensions of L. monocytogenes. It can be seen that, for the same applied dose level, the most rapid inactivation rate was found upon exposure to wave- lengths of 500 nm and less, with a 5.1 log10 reduction in bacterial population after exposure to a dose of 604.8 J cm)2, and this is likely due to the inclusion of UV wavelengths in the exposing light spectrum. Within the visible-wavelength region tested, L. monocytogenes was most susceptible to light of wavelength 400–500 nm, with an approximately 50% faster inactivation rate, at the same applied dose level, than that…
We have a many different Blue Light products that can help sanitize delis, meat packing plants, grocery stores, restaurants and more from Listeria and Salmonella.
If you have and application for one of our out SAFE Blue Sanitizing Lights but not sure which product to use tive one of our Blue Light Specialist a call 513-702-3533 or 407-230-9096 or 513-325-1623 or you can email us for more information firstname.lastname@example.org
