Hmmm...I didn’t know dogs could be affected by Salmonella. After all, there are plenty of people that swear by the BARF diet of raw meat and chicken, and I’m sure their dogs are consuming salmonella, based on the prevalence of it in raw chicken.

Dawn, I have one dog on the barf diet but have another whose immune system is so compromised that she cannot handle the normal flow-through of bacteria. It can depend on the dog.
Producers of this type of product are much more worried about the people handling the product and cross contamination then the dogs getting sick.
After all drinking out of the toilet and eating out of the cat box is going to give them a far higher bacteria load then this type of thing.
I see dogs every once in awhile with salmonella. Cats are more commonly infected with salmonella, especially the ones that catch lizards and birds. Dogs that lick or catch lizards or snakes also get salmonella. A dog or cat with bloody diarrhea from salmonella is a mess...
I won't allow the bag of dogfood in the kitchen anymore, and I always very carefully wash the food bowl.
