I'd not let it be near my gear for a while. I don't really know how to get rid of fungus that can grown on camera gear, other than give it some sun, and find a way to chemically clean it. The fungus spores will probably remain in the camera, and spores are typically environmentally resistant (that is, only extreme temperature and extremely noxious chemicals can destroy spores). I'd clean it, use it, and after quite a bit of use, I might start to feel it safe to keep with my other gear (assuming the remaining spores have shaken out).
