This would probably create resiliency for egg supply, but given that a source of bird flu is wild birds and transfer to and from humans would increase mutations wouldn't it likely increase probability of more bird flu and more human cases?
(cleaning eggs also removes some of its natural barriers, making it mandatory to refrigerate them to keep them edible)
If you wash your eggs before using them, you will never get salmonella.
In thirty years in Europe, I’ve had a single incidence of salmonella infection when I handled egg shells badly while doing a Carbonara (which requires raw eggs to be spread right over the plate). This really, really isn’t a problem if you follow minimal hygiene when cooking (don’t touch food after touching shells without washing your hands in between.
