Campylobacter can come from so many different sources. Even raw produce is considered a common culprit.
Why do you think it is that? At the risk of being insensitive - its hallmark is bloody stools. If that is what is making you think you have it a Z pack should clear things up. It rips through daycare centers and schools via person to person. As long as you are taking the usual precautions with handling raw meat I would not jump to a conclusion that it is the source of what ails you.
I caught my baby chewing on my dog's cow shin bone treat right after he dropped it which was right after he ate a raw grind of lamb , chicken , turkey.
I had a minor " ooohhhh nooooo" moment. Yes , the baby got the trots for a few days. Pedialyte , light meals he was fine . I also caught my 4 year old poking a raw steak that was marinating on the counter ( for us ) ..and he was licking his fingers after dragging them through the marinade and raw juices. He is part Viking I think , he was fine lol
At the end of the day unless you are an immuno compromised person , and if you practice safe handling skills for the dog's and your own raw meat handling , you should be fine.
If someone in your office has a stomach bug I would bet bottom dollar that is the culprit. Stomach bugs in schools and offices almost guarantee people fall one by one . How long did it take patient zero to be better? Bet you have the same timeline
