The research behind our zoo and wildlife aftercare guidance
Accreditation standards, disease surveillance and equipment specifications shape how collection animals are handled after death. Here's which sources we use, how we grade them and where our own estimates fill gaps.
- Standards and surveillance cited at source
- Manufacturer figures flagged as such
- Report errors through the form
Method
How our research library is built and graded
Our network of aftercare sites shares a single research library of more than 890 cited facts. Every entry records its source, publication year, geography and a plain statement of what was measured. Where a planner's question has no published answer, such as how long a large carcass takes to cremate at a known burn rate, we calculate it ourselves. The library holds more than 170 of these original estimates, each marked "our estimate" on the page.
Sources are graded. Primary covers accreditation standards, government surveillance data, peer-reviewed studies and manufacturers' own specifications for their equipment. Secondary covers guides, insurers, retailers and market analysts that report or summarize. For institutional work, most of what we cite is primary, because standards and surveillance are published by the bodies that set or collect them.
Estimates carry a confidence rating: high for simple arithmetic on primary data, medium for one assumption, low for several. The full list follows this section, with every formula shown so your team can check or adapt it.
Our own numbers
How we calculate our estimates
Our pages cite 890 published facts, each linked to its source. Where no one has published a figure that answers a reader's question, we calculate one ourselves from those facts and label it "our estimate", with the method shown.
Local estimates on city pages (for example, how many households in a city have a dog) use the city's population, the national average household size and the national share of households that keep that species. Yearly losses divide those households by the species' average life expectancy. Households with several pets count once, so these figures are deliberately conservative: a floor, not a ceiling.
Cremation rates on local pages describe people, not pets. We show them as context for how a community thinks about cremation, never as a pet statistic.
Each estimate below has a confidence rating. High means simple arithmetic on primary sources; medium means one assumption; low means several assumptions or a source from another country. If you spot a better source, tell us and we'll update the figure.

| AZA standard on necropsy of deceased animals | Standard 2.5.1[2] | Primary |

Capacity figures come from equipment makers. An agricultural and animal-control incinerator is specified for a 1,500 lb load[7], and a commercial pet crematory rated for 1,000 lb loads averages about 250 lb/hour[8]. From these, by our estimate, an 1,100 lb animal uses about 73% of a 1,500 lb load[9], which is why very large animals are generally cremated one at a time.

Reading with care
Where our figures need a caveat
Manufacturer specifications are best-case. Burn rates are measured under ideal conditions by the people selling the machine. Real throughput depends on the animal's fat content, the operator and the chamber's condition. We label these figures as specifications and treat our timing estimates as minimums.
Ash rules come from other species. Pet guidance says remains weigh about 3-5% of body weight[11]; a study of human cremations found about 3.5%[12] in adults. Nobody has published comparable figures for elephants or giraffes, so we present ash volumes for very large animals as rough guides.
Surveillance numbers move. Disease figures such as the avian influenza counts are snapshots with a stated end date. We quote the date alongside the number and update it when the agency publishes a new total.
Gaps
What nobody has measured yet
There's no national dataset on how zoos, aquariums and sanctuaries dispose of animals that die. We know how many animals are in accredited care and what the standards require, but not how often each method is used, what institutions pay or how long they wait for a vendor. We won't fill that gap with guesses presented as facts.
Instead, we borrow carefully from neighboring fields and say so. Livestock data tells us that only about 50%[13] of US states have rendering plants, which limits one alternative for very large bodies. Wildlife disease rules tell us that many states restrict whole-carcass imports of deer and elk to slow chronic wasting disease[14]. Those findings describe the landscape an institution works within, not institutional practice itself.
You can check those neighboring sources yourself. The extension network's guide to horse disposal options supplies our rendering and large-animal cost benchmarks, and a peer-reviewed review of University of Tokyo necropsy cases shows how much pathology work exotic species already generate. How readers actually handle these cases is on our live poll results, labeled as reader answers. The services page and locations pages apply these sources to real routes and regions, and our cost comparison article shows the benchmarks at work.
If your organization has published data on mortality handling, or would share anonymized figures, we'd like to hear from you through the form.
Standards
Our editorial standards
- Traceable sources only. Every number links to a named standard, agency, study or publisher.
- Jurisdiction stays attached. A US state rule is described as a state rule; a UK finding stays a UK finding.
- No invented case studies. We don't publish institutional testimonials or client stories. Scenarios are marked as illustrations.
- No legal or veterinary instructions. We point to the authority that decides; we don't replace it.
- We don't operate equipment. We're an independent guide and request service, and providers set their own terms.
More about who runs this site and how requests are handled is on our about page. Our poll pages collect informal, anonymous answers from readers and are never presented as research.
Corrections
How to report an error or a newer source
Use the form at the top of this page. Under "What do you need?" choose "Something else", then in the notes give the page address, the statement you're questioning and a link to the source you'd suggest. Pathologists, curators and regulators often see updated standards or data before we do, and we welcome the correction.
We compare the report against the original publication, correct the page where needed and update its review date. Any estimate built on the figure is recalculated across the network. We'll email you to confirm the outcome.

What we don't claim
- We don't claim any vendor can handle every species or size; capacity and access vary widely.
- We don't interpret permits or disease rules for your site. Your veterinarian and animal health authority decide.
- We don't claim our timing or ash estimates are exact; they're planning minimums and rough guides.
- We don't accept payment for vendor placement.

Questions people ask
Why do you treat manufacturer burn rates cautiously?
They're measured by the maker under good conditions. Real cremations vary with the animal's size, fat and bone density and the equipment's age. We quote the specification, name it as one, and treat any time we calculate from it as a minimum.
Do you cite AZA standards directly?
Yes. Where we refer to necropsy and cadaver storage expectations, we cite the specific accreditation standards by number. Non-accredited facilities, sanctuaries and rehab centers may follow different rules, so check which apply to you.
How current is your disease surveillance data?
Each figure carries the end date given by the publishing agency, such as the wild bird avian influenza counts through September 2025. Outbreak numbers change quickly, so check the agency's latest release before making decisions.
Can we use your estimates in our own planning documents?
Yes, as a starting point. Each estimate shows its formula and inputs so your team can substitute your own weights and equipment figures. Cite the original sources rather than our site where you can.
What counts as a secondary source for institutional topics?
Summaries and reports by organizations that didn't collect the data themselves, such as association fact pages, guides and market reports. We use them where primary data isn't published, and label them clearly.

- [10] At an average rate of 250 lb per hour, the burn phase for a 1,100 lb horse would take at least about 4.4 hours, not counting preheating and cool-down. Our estimate: 1,100 lb / 250 lb per hour. How we calculate.

- [12] In a study of 100 commercial human cremations, cremated remains averaged about 3.5% of total body weight in adults, 2.5% in children and about 1% in fetuses; this is the benchmark most pet crematories adapt for animals.
