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.

Abstract

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.
