I think I'd much rather contract salmonella than an intestinal parasite. EW.
One of my great fears of handling the poo. Gloves and wash your hands afterwards!
On that note (and not a vent), we just got a new head-vet in at work. We are all still feeling her out, I think, but she jumped a few places in my book when we were in an appointment and the owners mentioned they switched to grain free for food trial purposes and she said, "Well, it's always best to feed grain free anyway."
Hooray for a vet that potentially may not be pushing SD/Iams/Purina!
