Raw eggshells in the garden?
Absolutely!
We get eggs from our neighbors chickens.
When we cook with them them we save the shells and let them dry out.
(I have NEVER heard of anyone who washes/cooks eggshells before composting them).
After that we crunch them up and either feed them back to the chickens or dig them into the garden.
Chicken manure is great too (as well as horse/cow manure) and it's dug in after it's aged in the compost pile.
You have to realize that while there are germs that can harm us - many germs/bacteria benefit us as well.
In fact it would be quite unhealthy (and fairly impossible) to live in a sterile environment.
Probiotics = good bacteria that are useful to aid our digestive processes.
Bacteria on our skin is necessary.
Studies have been performed on the biodiversity of belly button bacteria!
No - really - I'm not kidding:

I love the summer because I enjoy gardening - and with me - it's a full contact sport.
If I can come in at the end of a day covered in sweat, dirt and mud - it's been a good day!
Did you know there are spas where you can get a mud bath?
Throw out the sanitizers, get good and dirty every so often and scrub up afterward with plain soap and water.
It's good for you!
I know this is a phobia of yours but perhaps instead of researching all the dire diseases one could catch from raw egg shells - maybe you should learn about the benefits of the micro flora and fauna that live on us and inside us.
