Lahore Zoo has been criticized for not having the level of medical facilities expected in a modern zoo. Zoo officials reported in April 2005 that three female black-footed gray langurs died due to cold weather the previous winter. In November 2005, a male mandrill and male puma died at the zoo. A female Asian black bear died in mid-February 2006. In September 2006, some animals at the zoo were diagnosed with tuberculosis, which can also be transmitted to humans, but early detection and treatment prevented an outbreak. In January 2009, a female giraffe was attacked by a plains zebra and died soon after due to injuries.
