Can You Butcher Your Own Animals in Massachusetts? What the Law Actually Says
July 12, 2026
Massachusetts allows you to butcher animals you raise yourself — but only under a specific set of conditions that carry real legal weight. The state draws a firm line between personal-use slaughter and commercial processing, and crossing that line without proper licensing puts you at risk of regulatory action.
Whether you raise backyard chickens, keep a small herd of pigs, or run a hobby farm with cattle and goats, understanding where the exemptions begin and end is essential before you pick up a knife. This guide walks through the Massachusetts rules that apply to home butchering, the animals covered, humane slaughter requirements, local zoning considerations, and what to do if you want to eventually sell meat.
Important Note: This article is for general informational purposes only and does not constitute legal advice. Massachusetts regulations can change, and local rules vary significantly by municipality. Always verify current requirements with the Massachusetts Department of Public Health (MDPH) and your local Board of Health before proceeding.
Can You Butcher Your Own Animals in Massachusetts?
Yes — with conditions. Massachusetts regulation 105 CMR 500.030(F) explicitly exempts the slaughtering by an individual of livestock or poultry of his or her own raising on his or her own premises, and the preparation of the carcasses, parts thereof, and food products of such animals on his or her own premises exclusively for use by him or her and the members of his or her household and his or her nonpaying guests and employees, provided that such livestock or poultry is healthy and is slaughtered and processed under sanitary standards, practices, and procedures that result in the preparation of food products that are sound, clean, and fit for human food.
In plain terms: if you raised the animal, you butcher it on your own property, and you only feed the meat to yourself, your family, or unpaying guests, you generally do not need a permit from the state. The moment you step outside those boundaries — selling the meat, hiring someone else to slaughter for you, or processing animals you did not raise — the exemption disappears and licensing requirements kick in.
For a broader look at how this personal-use framework works across the country, see our overview of butchering your own animals at the federal and state level.
The Personal Use Exemption in Massachusetts
Individuals who raise meat and poultry for personal use and slaughter and process the animals may do so without first obtaining a permit from the Massachusetts Department of Public Health (MDPH) or the local Board of Health (LBoH) within whose jurisdiction the slaughtering and processing occurs. This is one of the more permissive aspects of Massachusetts law for small-scale producers.
The product generated from the slaughtering and processing may not be sold or given away and is solely for use of the owner of the animal, his or her immediate family members, and/or non-paying guests. That restriction is non-negotiable under state policy.
At the federal level, the same logic applies. The personal use exemption under 21 U.S.C. § 623(a) applies to “the slaughtering by any person of animals of his own raising” and the associated processing “of such animals exclusively for use by him and members of his household and his nonpaying guests and employees.” Massachusetts mirrors this federal framework at the state level through 105 CMR 500.030.
Duly authorized inspectors may inspect to confirm that the persons conducting operations that are exempt from regulation are in compliance with the appropriate conditions for exemption provided in 105 CMR 500.030(F). The exemption is real, but it is not invisible to regulators — you can still be inspected to verify you are operating within its bounds.
Pro Tip: Keep a simple written record of the animals you raise — species, approximate acquisition date, and intended use. This documentation can help demonstrate compliance if an inspector ever asks whether the animals were “of your own raising.”
Which Animals Can You Butcher in Massachusetts?
The personal use exemption covers livestock and poultry you have raised yourself. In practice, that includes the most common farm animals kept by Massachusetts residents.
- Cattle — beef steers, dairy cull cows
- Swine — pigs and hogs raised on your property
- Sheep and goats — both are classified as livestock under state and federal law
- Poultry — chickens, turkeys, ducks, and geese raised by you
- Rabbits — included in the broader livestock definition when raised commercially or for personal use
Included in the scope of regulated operations are custom slaughter and custom processing operations, and persons who slaughter or process wild animals that have been raised commercially for wholesale, such as, but not limited to, rabbits, buffalo, deer, elk, and emus. These animals are included in the definition of livestock or poultry, and their products are included in the definition of meat or poultry. If you raise any of these species yourself for personal consumption, the exemption can apply.
Wild game is a different matter. Massachusetts regulations regarding the slaughtering and processing of meat and poultry (105 CMR 500.030 and 105 CMR 500.031) do not specifically address raised or wild game animals that may be subject to slaughtering and processing and intended for use as human food. If you harvest deer or other wild game, wild-caught animals such as deer and moose may be processed at a custom facility after notification to the Department as required by 105 CMR 500.031(K)(9)(a).

Humane Slaughter Laws in Massachusetts
Massachusetts does not operate a standalone state humane slaughter act for private operations the way some states do, but federal humane slaughter standards still apply to anyone operating a slaughter facility — and best practices are expected even at the personal-use level.
All persons who slaughter livestock shall comply with federal regulation 9 CFR Part 313: Humane Slaughter of Livestock. Ritual slaughter as defined in M.G.L. c. 94, § 139G and the handling or other preparation of livestock for ritual slaughter shall be exempt from this requirement.
Nearly all states provide by law that an animal must be “rendered insensible to pain” prior to being hoisted or shackled for slaughter. Most of these state laws also contain a religious/ritual slaughter exception whereby an animal may be killed by severing the carotid artery, causing loss of consciousness prior to being hoisted. Massachusetts follows this same general framework through its incorporation of federal standards at licensed facilities.
For personal-use slaughter on your own property, the regulation requires that animals be healthy and that processing occur under sanitary conditions that produce food that is sound, clean, and fit for human consumption. While the state does not send an inspector to every backyard slaughter, the legal standard still exists — and the Massachusetts Department of Agricultural Resources (MDAR) can provide resources on best practices for killing animals for personal use.
| Slaughter Method | Allowed for Personal Use? | Notes |
|---|---|---|
| Captive bolt (stunning) | Yes | Standard humane method for cattle, swine, and sheep |
| Firearm (gunshot to head) | Yes | Commonly used on farms; must comply with local discharge ordinances |
| Ritual/religious slaughter | Yes (with exemption) | Exempt from 9 CFR Part 313 under MGL c. 94, § 139G |
| Cervical dislocation (poultry) | Yes | Accepted method for small poultry at personal-use scale |
Local Zoning and Municipal Rules in Massachusetts
State law sets the floor, but local rules can raise it considerably. Massachusetts is a home-rule state, which means cities and towns have significant authority to regulate what happens on private property within their boundaries — including whether you can keep livestock at all.
Keeping backyard chickens and poultry is regulated at the city and town level. Check your city or town’s bylaws or website to confirm if keeping backyard chickens is permitted in your area, what the requirements are, and general best practices. Contact your city or town clerk’s office if you have questions, concerns, or would like to verify local laws.
On-site slaughter in residential areas may be restricted or prohibited due to noise, odors, visibility, waste, or public nuisance ordinances — even where chicken ownership is allowed; local boards of health often enforce these quickly. This is a critical point for suburban and urban Massachusetts residents. Even if the state exempts your home slaughter from permit requirements, your town may effectively ban it through nuisance or zoning rules.
Rural towns tend to be more permissive. As one example from Pembroke’s livestock regulations, all buildings, fences, or other structures constructed for the keeping of livestock shall comply with existing building and zoning regulations and shall be maintained at least fifty feet from the homeowner’s dwelling and at least fifty feet from neighbors’ dwellings, except chicken coops, which shall be more than twenty-five feet from the homeowner’s dwelling or by zoning regulations, whichever is greater. Setback rules like these vary from town to town.
Key Insight: Before building any livestock structure or planning a home slaughter, call your town’s zoning enforcement officer and your local Board of Health. These are two separate offices with two separate sets of rules — both can affect what you are legally allowed to do on your property.
Massachusetts also has no statewide limit on flock or herd size for personal-use farming. Massachusetts has no statewide chicken limits or bans, but the Department of Agricultural Resources (MDAR) enforces biosecurity, disease prevention, and best practices. Town bylaws set flock sizes, rooster rules, permits, and coop setbacks.

Can You Sell Meat After Butchering Your Own Animals in Massachusetts?
No — not under the personal use exemption. This is the hardest boundary in Massachusetts home butchering law, and it applies without exception to anyone operating under the exemption.
Products that have been slaughtered and processed based on custom exempt guidelines may not be sold or donated. The same principle applies at the state level: the product generated from the slaughtering and processing may not be sold or given away and is solely for use of the owner of the animal, his or her immediate family members, and/or non-paying guests.
If you want to sell meat in Massachusetts, you need to enter the licensed commercial system. No person shall engage in the slaughter of livestock or poultry unless he has obtained a license from the department. No person shall process or manufacture meat or meat food products, poultry or poultry products, in an establishment unless he has obtained a license from the department. These requirements under MGL c. 94, § 120 apply to anyone operating as a business.
Poultry producers do have one additional avenue. Unlike the stricter slaughter regulations for red meat, USDA allows farmers raising fewer than 20,000 chickens or 5,000 turkeys per year to process their own birds on-farm. However, selling that poultry in Massachusetts still requires state-level licensing. Some states, like New Hampshire and New York, are relatively lax; others, like Massachusetts and Connecticut, ask more of producers before allowing them to process poultry on their own farm and sell the meat.
The short answer: if money changes hands for the meat, you are no longer operating under a personal use exemption. Plan accordingly.
Custom-Exempt Facilities in Massachusetts: An Alternative Option
If you own an animal but prefer not to slaughter it yourself, or if you want a more controlled processing environment, a custom-exempt facility is a legitimate middle path. These facilities slaughter and process your animal for you — but the resulting meat still cannot be sold.
Custom slaughterhouses operate under a provision of the federal code that allows the owner of an animal to process it without federal or state inspection as long as the meat is for the owner’s household and is not sold. The owner butchers the animal under the personal use exemption, but an employee or operator of a custom slaughter establishment butchers the animal under the custom slaughter exemption.
Under the custom slaughter exemption, the establishment must be operated in a sanitary manner, there are additional record-keeping requirements, and the meat or carcass must be marked “Not for Sale” and separated from other meat products. These requirements protect the integrity of the exemption and keep custom-processed meat out of commercial channels.
One practical approach used by some Massachusetts producers involves co-ownership. Producers may sell portions of an animal — for example, a quarter steer or a half hog — to several consumers while the animal is still alive. At that point, the consumers become co-owners of that animal, and once the animal is completely sold the producer acts as an agent to arrange transportation to the slaughter and processing facility. Each individual consumer/owner is then responsible for choosing how the animal should be processed, as well as paying both the producer for the animal and the processing facility for the processing.
Custom slaughter plants are inspected periodically. These plants are, however, expected to meet the same requirements for sanitation that USDA-inspected plants must meet, as well as keep certain specified records. For a comprehensive overview of meat processing law frameworks across all states, the National Agricultural Law Center’s state meat processing compilation is a useful reference.
Massachusetts also has mobile poultry processing units (MPPUs) available for small-scale producers. A mobile poultry processing unit is essentially a “chicken slaughterhouse on wheels” that travels to individual farms, allowing farmers an avenue to legally process and sell their own birds without having to build and license their own state-approved on-farm facility. In Massachusetts there are two state-approved “mainland” units — one in Eastern Massachusetts managed by New Entry Sustainable Farming Project and one in the Pioneer Valley managed by New England Small Farm Institute — and another operated by Island Grown Institute on Martha’s Vineyard.
Who to Contact in Massachusetts Before You Butcher
Before you proceed with any home slaughter — even under the personal use exemption — reaching out to the right agencies protects you legally and helps you stay on the right side of both state and local rules. Here is where to start:
- Massachusetts Department of Public Health (MDPH) — Food Protection Program: The primary state authority on slaughtering and processing regulations. Their published policy on slaughtering and processing of meat and poultry (available at mass.gov) explains private use versus commercial requirements in plain language.
- Your Local Board of Health (LBoH): Every Massachusetts municipality has one. The LBoH has jurisdiction over the area where slaughtering and processing occurs. Even when a state permit is not required, your local board may have its own rules or nuisance standards that apply.
- Massachusetts Department of Agricultural Resources (MDAR): MDAR will perform a flock inspection and can provide resources about best practices for killing for own use, composting/waste, and related matters. This is especially relevant for poultry producers.
- Your Town’s Zoning Enforcement Officer: Confirm that your property is zoned to allow livestock keeping and on-site slaughter before you invest in animals or equipment.
- USDA Food Safety and Inspection Service (FSIS): For questions about federal exemptions, custom slaughter registration, and the rules that govern any facility processing animals for you, the National Agricultural Law Center also maintains a state-by-state contact directory for FSIS and state agencies.
For people or companies interested in opening a meat slaughter and processing facility, there can be requirements ranging from health and sanitation to waste disposal to specific facility or building requirements. Because the requirements can vary so much from place to place, it is really important to obtain the correct information before any final plans are made, which allows potential operators to manage risk appropriately.
Massachusetts animal law is also comprehensively catalogued by the official Mass.gov animal law resource page, which links directly to the relevant General Laws and regulations. For the full text of the state’s slaughter licensing requirements, see MGL c. 94, § 120 and the prohibited acts outlined in MGL c. 94, § 127.
If you raise animals and are curious about their biology — including which species have multiple stomachs and how that affects their processing — or want to understand more about stray and feral animals that sometimes end up on rural properties, those resources can round out your knowledge as a responsible animal owner in Massachusetts.
The bottom line: Massachusetts gives personal-use farmers a workable exemption, but it comes with clear limits. Raise the animal, slaughter it on your property, eat it with your family — that is legal. Sell it, give it away, or hand the slaughter off to an unlicensed third party — that is not. Know the rules before you act, and when in doubt, make a phone call to MDPH or your local Board of Health first.
