Listeria Prevention
How do you prevent listeria from growing in your plant? One way you can do Listeria Prevention that not many are thinking about but actually works quite well and does not cost a lot of money, works 7 days a week, takes no benefits and always shows up on time is SAFE Blue Listeria Killing Light. Don’t take my word for you take the word of many renowned Scientific experts that have studies this many times over found the same thing….SAFE Blue Light in the visible light spectrum kills both Listeria and Salmonella. Here area a few short takes from their research…..

ABSTRACT
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 wavelengths
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 population.
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 bactericidal
effect also evident at other wavelengths between 400 and
440 nm. Identification of the optimum bactericidal wavelength
enabled the comparison of inactivation using 405(±5) nm filtered
light and a 405 nm light-emitting diode (LED) array (14 nm
FWHM). Results demonstrate similar inactivation kinetics,
indicating that the applied dose of 405 nm light is the important
factor. Use of the 405 nm LED array for the inactivation of
L. monocytogenes and other Listeria species resulted in similar
kinetics, with up to 5 log10 reductions with a dose of 185 J cm)2.
Comparative data for the 405 nm light inactivation of
L. monocytogenes and other important foodborne pathogens,
Escherichia coli, Salmonella enteritidis and Shigella sonnei, are
also presented, with L. monocytogenes showing higher susceptibility
to inactivation through 405 nm light exposure.

DISCUSSION Listeria Prevention
The combination of optical filters used in this study demonstrated
that the most effective visible-light wavelengths for the
inactivation of L. monocytogenes were in the violet ⁄ blue region
between 400 and 450 nm.
The facts are Listeria and Salmonella cost the food packaging industry a ton of money every year. Can you afford not to look at this amazing technology?
