The Shanghai Zoo held a meeting to address safety loopholes and standardizing operational process on Dec 18, after a keeper was fatally mauled by a South China tiger in the zoo the previous day, Beijing News reported.

The 9-year-old tiger is still at the zoo's breeding site, where it mauled the veteran keeper Zhou Jianhua, 57, to death when he was cleaning its cage. The zoo has no plans to punish the animal.

Experts said some zookeepers use ankle chains temporarily on animals when they show obvious irritability or strong signs of an inclination to attack.

However, every zoo has its own operational standards on how to keep wild animals, experts said, and no casualties would occur if zoo management and workers strictly followed those rules.
