SAN FRANCISCO (KRON) – A new report said the San Francisco Zoo is not a safe environment for workers, the public and even its animals.  Despite the zoo following federal rules and regulations, the San Francisco Animal Control and Welfare Commission says the establishment fails in animal enrichment due to outdated enclosures.  The SF Zoo has a history of animal violence. In 2006, a Serbian tiger escaped and killed a man. San Francisco police made the controversial decision to put down the tiger. Since the tragic incident, the zoo has made updates, which are still not enough, according to SF Animal Control. According to the memo, the commission suggests the zoo must change the following for the “zoo animals to thrive”: The enclosure should provide enough room for the animals to exhibit normal behavior. It should allow a space for animals to retreat from human view. retreat to an indoor area. It should be pleasant to the eye of the patrons and allow the patrons an opportunity to see the animals exhibiting natural behavior. It should provide ample opportunities for behavioral enrichment. It should be clean and safe for the animals, animal caretakers, and the public.  Attorney says San Jose City Councilman’s texts were ‘fantasy,’ not reality The committee said the zoo's enclosures are “extremely outdated.” The committee even describes part of the zoo as “dilapidated” and said the facility is in need of a “comprehensive strategic re-design plan to modernize the habitats.” Another primary concern is animal enrichment and habitat. Providing a natural habitat that will allow the animals to exhibit behaviors that will be natural in the wild. The committee said that the enclosure does not allow this, which they said causes the visitor to have an “uninspiring” visit. KRON4 has reached out to the San Francisco Zoo for comment and is awaiting a response.
