[Effects of different chicken breeding on microbiological characteristics of fresh eggs].
The influence of three different systems of chicken breeding (battery, outdoor and free-range type) on contamination of the shell, yolk and albumen on category A eggs was evaluated. The eggs collected from free-range type did not resulted in conforming according to Italian legislation (5%) that foresees total absence of Salmonella spp. both on shells that yolk and albumen. Moreover the handled eggs can transmit microorganisms present on the shell because non-hygienic operator's hands favour horizontal bacterial transmission. In conclusion, this survey revealed that the breeding type as well as storing time and handling quality influence the product quality.
