A Florida zoo has been fined more than $14,500 after a worker was injured by a 4,000 pound white rhinoceros earlier this year.

According to WILX News 10, Your Breaking News and Weather Authority, the U.S. Department of Labor's Occupational Safety and Health Administration cited the Jacksonville Zoo with failing to protect workers from recognized hazards when they train and feed the rhinos.

It says the zoo also didn't follow the rules of notifying the federal agency within hours of the employee's hospitalization.

Zoo officials say they're appealing the citations and fine.

The Zoo's Executive Director previously said the 50 year old rhino, Archie, bumped a female zookeeper with his horn in February.  Officials say the worker spent a night in a hospital and has since returned to work.
