INDIANAPOLIS ZOO LOSES “GOLD STANDARD” ACCREDITATION 
THE CONCERNS BEHIND THE DECISION

A workplace culture concern, a documented enclosure citation and a question for the public: How does a zoo demonstrate lasting accountability?

The Indianapolis Zoo announced on September 28, 2026, that it had not retained accreditation from the Association of Zoos and Aquariums (AZA). According to the zoo’s account reported by WTHR, AZA identified longstanding organizational concerns involving communication, internal consistency and collaboration across departments. The zoo said AZA wanted more time to assess whether its workplace culture improvements would last.
ㅤ
That explanation deserves attention. AZA’s accreditation review extends beyond animal exhibits. Its published process includes staff interviews and reviews of animal welfare, safety, security, institutional leadership and governance.
ㅤ
Earlier incidents are part of the public record:
ㅤ
In March 2025, WTHR reported that then-president and CEO Rob Shumaker was bitten on a finger while feeding a chimpanzee through a mesh barrier. It was an injury to a person during an animal interaction, separate from the escape that occurred later that year.
ㅤ
On November 14, 2025, a female chimpanzee named Mara was found outside her normal enclosure. In the USDA focused-inspection report you supplied, investigators identified an opening in welded wire mesh over the “tool use yard” that had gone undetected during daily enclosure checks. USDA cited the zoo for failing to maintain a primary enclosure that securely contained the animal. Staff implemented the escape protocol and returned Mara to a secure enclosure; the report says neither Mara nor any person was injured. The zoo closed the affected yard pending evaluation and repair.
ㅤ
The zoo also faced the theft of two endangered tortoises in October 2025 and a leadership change in 2026. These events warrant examination, but the publicly reported explanation for the AZA decision does not establish that any one of them caused it. Treating them as AZA’s findings would go beyond the evidence currently available.

WHAT NEEDS TO CHANGE?

Keeping Wildlife Wild has raised concerns about animal care, safety and transparency across the zoo industry. The Indianapolis case brings those questions together. An enclosure check must find hazards before an animal escapes. Incident procedures must work when something goes wrong. Staff must be able to communicate concerns across departments, and leaders must show how problems were corrected.
ㅤ
The public should be able to see meaningful evidence of progress: what was repaired, how inspections and reporting were strengthened, whether staff concerns can be raised safely, and how the zoo and AZA will assess lasting improvement. The USDA report documents the enclosure failure and the zoo’s immediate response; it does not, by itself, tell us whether the later repairs or broader changes have proved effective.
ㅤ
Accreditation should reflect demonstrated practices over time. For the animals, employees and visitors who depend on the Indianapolis Zoo, that is the measure that matters now.
