Remember that it is important to wash your hands before and after feeding your pet, just as you would before your own dinner.  Pets can be exposed to salmonella and bacteria from foods you might have previously handled, like raw chicken or fruits and veggies with pesticides.

And it should go without saying, but please, wash your hands after you act as a human pooper scooper.
