Ali... I'm sure Bridget didn't interpret your comment as " going overboard!" the difference is, you trust your vet, which is how it should be!!! I trust mine as well.
I tend to go " overboard", and admit it! While being a single parent and dealing with two asthmatic kids, a cold for them while little, could be a death sentence. I would literally hand my pediatrician purell if I didn't see him wash his hands. He never got insulted.
I'm sure thats why my job gave me a position on the " safety patrol". Write doctors up, if they didn't wash their hands before seeing a patient. I never did of course... just grabbed them, told them to wash!
Remember all... soap and water is the best! Purell in my mind is for emergency use only. We all can use a simple reminder, everytime we handle our birds, our children... wash our hands! Nancy
