This guide explains animals euthanised with barbiturates in plain terms. When a horse, farm animal or other large animal is put to sleep by a vet using a barbiturate injection, the carcass cannot be treated like an ordinary fallen animal, because the drug residue places it in the highest risk category of animal by-product. Martlands handles these cases correctly as part of our fallen stock and ABP collection service, working from our family-run, DEFRA-approved facility in Burscough, Lancashire. Getting the category right protects the food chain, the environment and you as the keeper.
Why Barbiturate Euthanasia Creates Category 1 Material
Euthanasia by lethal injection commonly uses pentobarbital, a barbiturate that remains present in the carcass after death. That residue is the reason an injected animal is classified as Category 1 animal by-product, the highest risk tier, rather than the lower categories that might otherwise apply to a fallen animal. Category 1 material is subject to the strictest controls precisely because it must be kept entirely out of any route that could allow the drug to re-enter the food or feed chain. This is not a technicality; it is a central safeguard of the ABP framework.
What This Rules Out
Because the carcass is Category 1, several disposal routes that might be acceptable for other material are firmly closed. It must never be fed to animals, including hounds or kennelled dogs, and it cannot be sent down rendering routes intended for lower-risk by-products. On-farm burial and burning remain illegal regardless, and the presence of the drug makes improper disposal an environmental hazard as well as a legal breach. Our blog on the ban on burying or burning fallen stock sets out why these informal routes are prohibited across the board.
The Correct Route
An animal euthanised by injection must be collected by a licensed operator and taken to a facility approved to handle Category 1 material for safe disposal. Martlands holds the Category 1 ABP collection licence required to do this lawfully, so when you tell us an animal was put down by injection we route the carcass to the correct, approved destination from the outset. Telling your collector how the animal died is essential, because the disposal route depends entirely on it.
Storage Before Collection
While awaiting collection, keep the carcass away from other animals and out of reach of scavengers, ideally covered and on hardstanding. The drug residue means a euthanised carcass should be treated with particular care, as the risk it poses to wildlife and other animals if accessed is real. Prompt collection through our farm and fallen stock collection service is the safest approach.
Coverage and Documentation
Every Category 1 collection is fully documented, giving you proof that a euthanised animal was disposed of through the correct approved route. Our reach extends across the region including our Greater Manchester ABP collection coverage, and our DEFRA approved status and all-category licensing mean we can handle the most sensitive material lawfully.
Telling Your Collector How the Animal Died
The single most important thing a keeper can do is tell the collector how the animal died, because the disposal route depends entirely on it. An animal shot or killed by captive bolt is handled differently from one euthanised by injection, and only you and your vet know which applies. Horses and companion animals are very commonly put to sleep by injection, so equine keepers in particular should always flag this when arranging collection. Being upfront about the method is not an inconvenience, it is what allows us to route the carcass to the correct approved facility from the outset and keep the food and feed chain safe.
Arranging Collection
If a vet has euthanised an animal on your premises by injection, the carcass is Category 1 material and needs a licensed collector who can route it correctly. Call Martlands on 01704 776977, tell us how the animal died, and we will arrange compliant collection to an approved Category 1 facility.
