AFAIK, the egg paranoia is due mostly to bacteria contracted to the
outsides of eggs. In factory laying systems, the feces and whatnot builds up, and the eggs are laid in area that become contaminated. The bacteria then attaches to eggshells, and BOOM! salmonella.
When using at home, it's the fact that the inside of the egg comes into contact with the outside that makes it problematic. presumably, you'd wash your hands right after cracking eggs, thus eliminating the bacteria from yourself. But the egg that touched the shell remains.
Correct me if I'm wrong, bu that is my understanding.
Of course, eggs are washed before being distributed. These types of things are very verty rare. Having eggs at home, with clean nest boxes and coops, should give no cause for concern. But, as always, wash your eggs.
