Dogs are usually very tolerant of mega bacterial load. So salmonella and such don't affect them like it does humans. But, if your dog already has a compromised immune system then salmonella can be a problem. What I'm trying to say is... If your dog is sick because of the salmonella, that's not the only problem. You may have bigger problems.
Man, I sound like such a wet blanket! Hope your baby gets better soon!
