The Little Rock Zoo's 62-year-old female elephant, Jewell, has been euthanized after being found recumbent in her enclosure. A subsequent necropsy identified tuberculosis but concluded her death was due to other health problems. Zoo staff who were in close contact with Jewell may have contracted tuberculosis and they will be tested appropriately, state veterinarian Susan Weinstein said, but zoo visitors are not at risk because they do not have close contact with the animals.
