Unprovoked, predatory attacks by black bears are rare but highly publicized. Such attacks have accounted for all 23 deaths by noncaptive black bears across North America this century. Most occurred in remote areas where the bears had little or no previous contact with people, rather than in and around established campsites. The worst attack occurred in Ontario in 1978 when a black bear killed and partially consumed three teenagers who were fishing. Predatory attacks by black bears are usually done without bluster or warning.
People involved in such attacks can improve their chances by fighting rather than playing dead.
Deaths from such attacks average a little more than one every four years across the United States and Canada. Dozens of minor injuries, some requiring stitches, have occurred across North America when people petted or crowded black bears they were feeding or photographing. Under those circumstances, black bears may react to people as they do to bears with bad manners, by nipping or cuffing with little or no warning. Also, people who tease bears with food have been accidentally injured when the bear quickly tried to take it. Fortunately, black bears usually use at least as much restraint with people as they do with each other.
