Aaaaccckkk...I see enough strangers out and about who don't wash their hands when they should...so food handlers if not properly educated on the matter could really cause problems with any number of icky bacteria...nope can't even think about it this late in the evening.
Yep, ickky subject...eating at home is the ticket.
We fly alot. My Purell always garnered extra scrutiny. In fact, I even had it confiscated several times. My solution? I now soak some baby wipes with Purell and carry them with us in a zip lock bag. (a little tip for germ paranoid frequent flyers, like me)
