Zoos

The analysis can reconstruct the event using incident reports, surveillance video, keeper communications, staffing assignments, barrier and gate information, emergency procedures, training records, and the sequence of actions before and after the incident. Depending on the facts, a suitably qualified zoo expert may examine containment procedures, restricted areas, keeper access, public separation, emergency response, and whether established procedures were followed. AZA accreditation expressly includes safety policies, security, physical facilities, and staffing among the areas evaluated.

An enclosure is part of both the animal-care environment and the facility's containment system. Relevant evidence may include barrier configuration, gates and locks, shelter, space, substrate, environmental conditions, maintenance records, enrichment features, and modifications made over time. The appropriate analysis is species- and facility-specific; AZA animal-care resources and welfare guidance likewise emphasize that welfare assessment should account for characteristics of the particular species rather than rely on one universal measure.

Useful materials may include keeper logs, animal histories, feeding and enrichment records, training records, veterinary files, enclosure drawings, inspection and maintenance records, staffing schedules, surveillance video, incident reports, emergency procedures, accreditation materials, regulatory inspection records, and communications concerning earlier problems or changes. Where federal Animal Welfare Act requirements apply, USDA APHIS also regulates covered animal exhibitors and conducts oversight relating to humane care and treatment.
