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.

Background and Environment Affect Phenotype
An example of how genetic background affects phenotype can be seen in horses. The Extension gene in horses is responsible for their coat color. A wild-type gene (EE) produces black pigment in the coat, while a mutant gene (ee) produces red pigment. A...
