Efficacy of Ultra Violet Light for Elimination of Salmonella on Broiler Hatching Eggs

摘要: Abstract Germicidal UV light at a wavelength of 254 nm was tested as means to eliminate inoculated Salmonella from eggshells. Eggs with 105 cells were treated (600 μW/cm2) for 1 10 min. When inoculation made by drop suspension on the eggshell surface, treatment significantly lowered incidence positive eggs (P≤.05). However, less effective against when inoculum applied egg submersion dip. placed and covered fecal smear not eradicated treatment. As few ten in feces sufficient result following exposure μW/cm2). Following 100 cells, even intensity high 1600 μW/cm2 lead than 25% reduction percentage Salmonella. Continuous incubator did affect hatchability.
