Depends on how clean your floor is, I suppose. I wouldn't eat off a restaurant kitchen's floor, but in my own home I know it's clean. If there's been raw meat or meat juices on the floor since it was last cleaned you've got a much more significant health risk. Basically if your home is not filthy you're fine.
I don't think any meat products were on the floor. It's more like dirty shoes maybe walking around the floor that I'm worried about the most lol.
