Remember that this is an "inline" complex where the eggs are practically gathered the day they are laid and are never temp abused. We also vaccinate our birds using an autogenous salmonella vaccine derived from strains we isolate from the housing environment. That and regular sampling make me very comfortable that anything that might be there is at levels my immune system can easily handle. Most problems from eggs come from pooled eggs that sit on a steam table at improper temperatures for hours and hours.
It's science.
