"Zoonotic pathogens (Salmonella, Campylobacter spp.) as well as antibiotic-resistant pathogens (ESBL E. coli, MRSA) present on table eggs can cause health problems for consumers. Some egg packing companies in Germany use UV-C emitting low-pressure mercury vapor lamps to reduce the contamination on eggs. UV-C light-emitting diodes (LED) are a modern alternative. In laboratory tests, comparable reductions of zoonotic pathogens on the egg surface up to 3.2 log cfu/cm² by mercury vapor lamps and 1.6 log cfu/cm² by LED-technology were achieved with respect to their different intensity levels (~ 5 to ~ 2,4 mW/cm²). High bacterial counts and high organic loads had a protective effect on the pathogens. In practice, reductions of the aerobic total microbial count and Enterococci suspected colonies of 1 log were observed with both UV systems. Sensory alteration of eggs after UV-C treatment can be neglected. The UV-C LED-technology has been shown to be a suitable method for the eggshell decontamination, allowing a practical application in egg packing companies."
