Spoilage of Fresh Meat in Commercial Showcases
Listeria monocytogenes bacteriaThe growth of bacteria contributes to the discoloration of meat and leads to spoilage. Most display case lighting emits radiation which raises meat surface temperatures even in refrigerated display cases, leading to exponential bacterial growth.
Promolux fluorescent lamps and LEDs emit lower levels of UV and damaging visible spectrum radiation. Grocery stores that switch to Promolux lamps and LEDs soon notice that their meat display cases no longer smell unclean, because the lighting does not heat the blood and residue from meat packages to temperatures that encourage bacteria to grow.
