Have you tried Hanna Kroeger's vibrational homeopathic drops? I have had good results with those for numerous bugs, though it doesn't work overnight. I have a bit of a compromised gut from candida, etc. , and I pick things up easily. I had some undercooked salmon in a resataurant about a month ago, and I know that's where I picked up the bug that made me constantly blow stink bombs for the following couple of weeks. My homeopath/naturopath picked up trichinosis, which she said would cause that symptom. I took the kroeger remedy for Trich. 1 dropper twice a day, but wasn't getting results after about a week. I upped it to 3 x a day on her recommendation, and that seemed to resolve it. If you know for sure that it's salmonella and not some other parasite, the vibrational homeopathic that is attuned specifically to salmonella might help. I can get them at a local health food store, but you can order directly from the company, they are based in Colorad0 - Boulder, I think.
