Oops... a bit more info for you.
Raw food ( in and of itself) is NOT the issue. I fed my entire cattery raw food for 8-years. Unfortunately, I had to move state for a family medical emergency a few years back and until we could get relocated properly, I had to rent a building in the country to house my cats. Unbeknownst to me, the electrical power was very unreliable at that location and "brown outs" were common. Apparently the power went off during the height of the Summer causing all of the frozen chicken in my freezer (400 pounds) to spoil. By the time I went out to the building however, the freezer was working fine and it was NOT apparent that the power had been off...so I fed them the chicken...and continued feeding them the chicken daily, completely unaware that it was spoiled...
The cats all started getting loose stools and although I medicated with the usual stuff (metronidazole, Albon and Panacur) nothing seemed to help until my vet and i finally received a lab report back indicating Camphlobachtor...and were finally able to treat them and clear up the issue. It was terrible and affected my entire cattery!
My point is that it is not the chicken alone that is causing this gastro issue, but rather it is caused when an animal eats contaminated meat. It may not have anything at all to do with what you give them if they are trash diggers, etc. When it comes to raw food, one does need to exercise caution, but a case of Camphlobachter is no cause to discontinue feeding raw, if your boy is doing well on it.
Hope this helps.
