Food poisoning??? Tmi

I ate a pre packaged salad earlier which I believe is the cause of this. Ever since eating it I've had extremely bad diarrhea. It stopped a little bit so I decided to try a grilled cheese and chicken noodle soup. Immediately after I got diarrhea again. The kind of diarrhea where it feels like you're pissing lava out of your ass. I was totally fine before I ate that salad. Can you get food poisoning from salads? Would it only cause diarrhea? I always thought it caused more symptoms like fever (I checked mine and it was only 99.2) and puking..
