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.
评估了三种不同养鸡系统（笼养、室外养殖和放养型）对A类鸡蛋蛋壳、蛋黄和蛋清污染情况的影响。从放养型鸡群收集的鸡蛋不符合意大利立法（5%）的要求，该立法规定蛋壳、蛋黄和蛋清上均完全不存在沙门氏菌属。此外，经手的鸡蛋会传播蛋壳上存在的微生物，因为操作人员不卫生的双手会助长细菌的水平传播。总之，这项调查表明养殖类型以及储存时间和处理质量会影响产品质量。
