The Association of Zoos and Aquariums inspection report says six of the eight animal deaths between Dec. 10 and Jan. 24 at the Chattanooga Zoo resulted from "an unfortunate series of unrelated events."
"We do not see any medical or management connection between six of the eight deaths," states the AZA report.
Yet those "unfortunate" and "unrelated" events - the deaths of two snow leopard cubs, two muntjacs (Asian deer) and two marmosets (monkeys) - also showed up on a list of policy and management changes the AZA recommends and applauds in its eight-page special inspection report, released Monday by Chattanooga Zoo spokeswoman Robin Derryberry.
The AZA is a trade and nonprofit member organization that accredits zoos. It is holding its midwinter meeting with about 500 members this week at the Chattanooga Convention Center.
The snow leopard cubs were born in inclement weather while the mother was locked outside her den, and the two muntjacs were frightened by dogs during a zoo event before one had a seizure and fell into a koi pond in freezing weather. The other muntjac died 29 days later of a twisted colon, but zoo officials have said that was unrelated to the dogs incident.
The marmosets died days after it was discovered that because of an "administrative error," they went without food for two days. Zoo officials and the AZA have said the marmosets did not die from going without food. The animals already had significant weight loss due to an as-yet-undetermined liver ailment, they said.
AZA did fault the Chattanooga Zoo for the deaths of two tortoises, which inspectors said were housed in inadequate locations with insufficient heat.
Among the policy and management changes recommended by AZA, zoo officials already have or soon should:
The AZA's "special inspection" of the zoo in early March was prompted by a complaint from a former zoo worker and by a request from zoo officials after the death of Hank the chimpanzee on Jan. 24. Hank, 42, was one of the zoo's most-popular animals and the AZA inquiry did not include his death. His UT necropsy indicated he died of heart disease.

Hank's death unleashed a barrage or criticisms of the zoo as whistleblowers revealed that 10 animals had died in about six weeks in December and January. The AZA also did not probe the death of a gecko that zoo veterinarian Tony Ashley said died in November.
Derryberry, who also is a member of Friends of the Zoo, the organization contracted by the city of Chattanooga to run the zoo, said Sunday that the AZA continued the zoo's accreditation but will make a "progress recheck" in September.
The zoo, like other AZA accredited members, pays $3,125 a year to be a member of the organization, Derryberry said Monday. Additionally, the Chattanooga Zoo has 10 employees who have paid for their own individual memberships in AZA at a cost of $95 each, she said.
AZA spokesman Steve Feldman said neither the memberships nor the local meeting had any impact on the AZA's inspection and report.
"Clearly the accreditation commission was tough but also fair. Nobody's tougher on us than us," he said.
