When an egg is laid it emerges in a state where the shell is not fully
'cured'.  It remains quite porous and some have suggested that on
contact with the cooler temperature of the atmosphere, it is possible to
"suck in" contaminants from outside.  Thus _Salmonella_ that have been
sitting around a chook's cloaca may well get sucked in.

Thus newly laid eggs can be infected.  For a better description the 1990
edition of Topley and Wilson is a great read.
