DULUTH, MN (KDAL) - A Lake Superior Zoo employee was injured while working with an Amur Tiger during a routine training session. At the time of the accident on Monday afternoon, the zookeeper was using some venison as positive reinforcement. During the session, a piece of venison got stuck on the chain link barrier between the keeper and the tiger. When the zookeeper attempted to flick the meat into the holding area, her fingertip and the tiger's mouth arrived at the fence at the same time. The zookeeper was taken to a hospital for treatment of an injured fingertip. The animal care team has no reason to believe that the accident was the result of any aggressive behavior on the tiger's part and "Ussuri" will continue to be on exhibit at the zoo.
