I read most of this thread earlier and recall a statement made that there are no warning labels on dry dog food. Here is one from Eukanuba's bag:
Safe Handling Tips for any Pet Foods and Treats: Please wash your hands before and after handling any pet food or treat. Wash pet food bowls with soap and hot water after each use. For further information and tips please go to the following FDA website:

The only time I had a bit of an issue was due to my dog jumping in my bathtub to get at a case of defrosted pork ribs. That was a bit messy. Otherwise, no special cleanup at all. No face washing. He eats on a towel in the kitchen and after he's done, the towel goes in the washing machine.
