Leaving raw chicken uncovered for a day I sometimes leave some chicken unwrapped in the fridge inside the container, if I buy a two piece, and only want one. A girl who lives at my dorm told me it was a life threatening harm, to everybody’s food inside the fridge, since deadly bacteria’s spread,  to all the food. I read a similar post, where there was split descisions. Is there any danger to it, and if yes, how dangerous?
Food kept at refrigeration temperatures is relatively safe.  Any potential pathogens can not jump or fly about without something to propel them. Dripping can potentially contaminate. Cooking can render many things safe (if initially stored properly).  Keeping meats in closed containers is more sanitary (and respectful of others). However, to suggest that refrigerated unwrapped chicken, in a container, is "life threatening" sounds a bit extreme to me.
