TL;DR
California has no board named custom exempt slaughter board. CDFA's Meat, Poultry and Egg Safety Branch licenses custom livestock slaughterhouses. USDA FSIS still writes the federal rules under 21 U.S.C. 623 and 9 CFR 303.1. You need a state license to slaughter other people's livestock. The meat cannot be sold. Confirm current fees and review timing with MPES before you pour concrete.
What agency is the custom exempt slaughter board in California?
There is no board with that name. The agency that licenses custom livestock slaughterhouses is the California Department of Food and Agriculture Meat, Poultry and Egg Safety Branch (MPES). Federal custom-exempt rules still come from USDA's Food Safety and Inspection Service under 21 U.S.C. 623. [1] [7]
People search "board" because other trades have boards. Custom exempt slaughter California files do not sit with a standalone commission. You talk to a branch inside CDFA. You may also hear from FSIS if the plant is treated as a federal custom-exempt operation. [3] [4]
The state statute is the California Meat and Poultry Inspection Act. Food and Agricultural Code section 18650 says, "This chapter shall be known and may be cited as the California Meat and Poultry Inspection Act." [6]
I'd call MPES before I called a county clerk, and before I called a general USDA number. Ask who covers custom livestock slaughterhouses in your district. Write the name down. Files move when a person owns them.
Neighbor-state packets will mislead you. The custom exempt slaughter board in Arizona uses a different agency stack. So does Idaho. Do not drop those forms into a California folder and hope.
Do you need a license for custom exempt slaughter in California?
Yes. If you slaughter other people's livestock and hand the meat back, you need a California custom livestock slaughterhouse license from CDFA MPES. If you only kill animals you raised, for your own household, you sit under the federal personal-use exemption and you still cannot sell the meat. [1] [2] [6]
The federal line is blunt. 21 U.S.C. 623 limits custom product to use "exclusively for use, in the household of such owner, by him and members of his household and his nonpaying guests and employees." [1]
That is not a farm-stand rule. It is not a CSA rule. It is household use.
Slaughtering for neighbors, 4-H families, or a ranch client is custom work. That is a licensed plant activity in California, not a handshake on a gravel pad. MPES will want a premises, a sanitary plan, and a license file. Confirm the current application packet with the branch. Forms get revised.
Personal on-farm kill for your own freezer is a narrower story. The federal exemption exists. California still cares about dead-animal movement, inedible handling, and water discharge. You do not get a meat-sales ticket out of a backyard hoist.
If you want to sell cuts, custom exempt is the wrong door. You need inspected slaughter, state or federal. Custom is a service to an owner. It is not a marketing channel.
Is a USDA custom exempt plant the same as a CDFA custom house?
No. A USDA custom-exempt plant operates under the Federal Meat Inspection Act exemption and FSIS custom-exempt review. A CDFA custom livestock slaughterhouse is a state-licensed plant that does owner-returned work inside California. Most operators here live in the CDFA file, not in a daily FSIS inspection cage. [2] [3] [4] [7]
FSIS still writes the federal floor. 9 CFR 303.1 sets the custom operating rules. FSIS Directive 5930.1 tells inspectors how to review custom-exempt operations. [2] [4]
California can run its own meat inspection program. 21 U.S.C. 661 is the federal-state cooperation statute. That is why you can have state-inspected plants and state-licensed custom plants in the same county. [11]
I treat them as two folders. Folder one is the CDFA license. Folder two is whether FSIS also lists you as custom exempt. Ask MPES which folder they want you in. Do not guess based on a Facebook group in another state.
Inspected plants can sometimes do custom work under tighter separation rules. That is a different conversation with a different grant of inspection. If you are starting from zero, you are probably chasing a custom livestock slaughterhouse license, not a full inspected grant.
| Path | Who reviews it | Can the meat be sold | Carcass-by-carcass inspection |
|---|---|---|---|
| Custom livestock slaughterhouse | CDFA MPES | No | No |
| Federal custom exempt | FSIS custom-exempt review | No | No |
| State or federal inspected | CDFA or FSIS grant of inspection | Yes, if properly marked | Yes |
Colorado's stack is not yours. Read the custom exempt slaughter board in Colorado only as a contrast, not a template.
How much does custom exempt slaughter cost in California?
There is no honest statewide price for custom exempt slaughter California work. Plants set their own kill and cut fees. CDFA sets its own license fees, and those numbers move. Confirm the current license fee with MPES. Confirm the current hanging-weight price with the plants you would actually use or run. [7] [10]
I will not invent a per-head beef number. Anyone who quotes you a single California average without a year, a species, and a cut sheet is selling a vibe.
The money that breaks first-year operators is rarely the license invoice. It is the building, the hot water, the inedible barrel program, the septic or wastewater permit, and the months you pay rent before the first animal hits the rail.
If you are the livestock owner (not the plant), call three licensed custom houses and get the price in writing. Ask what is included. Kill only is not the same job as cut and wrap. Ask about hide, offal, rush fees, and no-show fees. Distances in the Central Valley and on the North Coast are not the same errand.
If you are building a plant, get the fee schedule from MPES in an email you can save. Then take that number to your county planning counter before you order steel. I have watched people spend on coolers they could not legally site.
Skip glossy turnkey plant brochures until planning and MPES have both said the parcel can hold the use. A printed federal kit does not set California fees.
How long does custom exempt slaughter take in California?
Nobody publishes a clock I would bet a construction loan on. Confirm current review time with MPES. County conditional-use permits and wastewater permits often take longer than the meat license itself. [3] [7]
If you are a livestock owner booking a slaughter date, the wait is the plant's rail schedule, not a state service clock. In busy months (late fall, after grass season, before holidays) you wait for a slot. Call early. Get the date in writing.
If you are standing up a plant, think in phases. County land-use first. Water and sewage next. Then the MPES packet and the on-site review. A kill floor is not a weekend build. I would not promise a friend they will be killing 90 days from a bare pad. I also would not tell them it must take two years. It depends on the parcel and the reviewer.
FSIS custom-exempt review, if it applies, runs on FSIS's calendar under Directive 5930.1. That is not MPES's calendar. [4]
No one can honestly guarantee approval or a date. If a consultant sells you a guaranteed open date, walk.
Hawaii and Florida run different clocks. The custom exempt slaughter board in Hawaii and the Florida board writeup will not predict Sacramento.
Can you sell custom slaughtered meat in California?
No. Custom slaughtered meat in California cannot be sold. The federal statute and the federal marking rule both lock it to the owner's household. Restaurants, retailers, and CSAs are out. [1] [5]
9 CFR 316.16 requires custom prepared carcasses and parts to be marked immediately with the words "Not for Sale" in letters at least three-eighths inch in height. [5]
If someone tells you that you can sell halves to the original owners as a work-around, they are describing the custom service itself, not a resale. The owner already owns the animal. You are charging for slaughter and butchering. You are not creating a salable commodity.
Sell it anyway and you have uninspected meat in commerce. That is the thing the Federal Meat Inspection Act and the state Act exist to stop. I would not test that line to save a slow week.
Inspected product (state or federal mark of inspection) is how you sell. Budget and build for that if sales are the business. Custom exempt slaughter California operators who try to wear both hats without separation get findings, or worse.
What paper does a first-year custom plant actually keep?
A first-year custom file is boring on purpose. You keep owner names, livestock identity, dates in and dates out, weights if you take them, and the Not for Sale trail. 9 CFR 303.1 is the federal list of custom operating conditions, including records and sanitation. [2]
CDFA will have its own license application, a premises description, and whatever current supporting forms MPES lists. Confirm the packet. Do not photocopy a 2018 PDF you found on a forum. [7]
Sanitation is not optional because you are exempt. Exempt means exempt from carcass-by-carcass inspection, not exempt from a clean plant. 9 CFR 416 is the sanitation framework FSIS uses. [8]
If you are assembling the federal custom-exempt document set while you wait on California forms, CustomExemptPath's $249 one-time USDA Custom-Exempt Kit at /start is a paperwork pack. It is not a CDFA license and it does not move an MPES review.
I would keep a paper binder and a cloud folder with the same PDFs. Inspectors ask for what they ask for, not for your favorite app.
Owner statements that the meat is for household use are common sense. Use whatever declaration MPES wants this year. I am not going to invent a form name that may already be retired.
What does a California custom plant have to mark, and how?
Mark it Not for Sale immediately after you prepare it, in letters at least three-eighths inch high, and keep that identity until the owner takes it. That is the federal marking rule in 9 CFR 316.16. [5]
Do not hide the words under a cute farm logo. The point of the mark is that a stranger can read it in a cooler.
Keep custom carcasses apart from any inspected product if you ever share a building with inspected work. 21 U.S.C. 623 says custom articles must be separated at all times from product prepared for sale and plainly marked Not for Sale. [1]
I'd stencil, not scribble. Ink that wipes off in a wet cooler is a finding waiting to happen. Bags and boxes need the same honesty. If you wrap, the words go on the package the owner walks out with.
Do you still need county land use and wastewater permits?
Yes. A CDFA license does not replace a county land-use permit, a building permit, or a wastewater permit. Start at planning. Ask if slaughter is allowed on that parcel, by right or only with a conditional use permit.
I would not buy land for a kill floor until planning puts the answer in writing. Rural zoning is not a free pass. Neighbors complain about smell, trucks, and blood water. Counties listen.
Septic sized for a house will not eat a slaughter floor. Budget a real wastewater conversation. That bill surprises people more than the license fee.
This is where projects die. Not on the meat statute.
Illinois and Georgia have their own local overlays too. See the Illinois board guide and the Georgia writeup if you are comparing parcels across states. Still call the California county you are actually in.
Does California allow mobile custom slaughter units?
California licenses mobile slaughter activity through CDFA MPES. A truck is not a loophole around a license. Confirm the current mobile slaughter unit rules and application with the branch before you weld a deck on a gooseneck. [7] [10]
Mobile units still return meat to the owner. Still not for sale. Still sanitary.
Counties may treat a mobile unit differently from a building. Some want a host-site agreement. Some want nothing until a neighbor calls. Get it in writing.
I like mobile for thin counties that will never support a bricks-and-mortar floor. I do not like mobile as a plan to dodge wastewater. You still have blood, paunch, and inedible. That material goes somewhere legal.
What animals can a California custom plant handle?
Federal custom slaughter language in 21 U.S.C. 623 names cattle, sheep, swine, and goats. Game animals show up in the custom preparation clause. Poultry sits under a different statute, the Poultry Products Inspection Act at 21 U.S.C. 464. [1] [9]
California licensing splits livestock custom houses from poultry plants. Do not assume a cattle license lets you hang turkeys. Ask MPES, in writing, which species your license can cover. [7]
Federal poultry exemptions exist on paper. California still licenses poultry work. Confirm with MPES before you count birds and call yourself exempt. Nobody has a clean public dataset that maps every CA poultry exemption case. Read 21 U.S.C. 464, then ask the branch what they will accept. [9]
Horsemeat is its own legal mess in California. I would not build a business plan on it.
Cervids and exotics can drag in animal-health rules (CWD, movement permits). That is CDFA Animal Health plus whatever the Department of Fish and Wildlife says. Confirm before you advertise elk dates.
What mistakes stall a California custom application?
The usual stall is a packet that describes a retail meat shop. Custom plants do not need a storefront. They need a clean kill, a clean cut, owner records, and a legal way to handle inedible.
People also send FSIS grant-of-inspection forms when MPES wanted a custom livestock slaughterhouse application. Wrong door, reset the clock. [3] [7]
Building before zoning is the expensive mistake. I would rather lose a design deposit than pour a floor on a parcel that cannot host slaughter.
Copying another state's checklist is next. Florida is not California. Neither is Arizona.
Last one: promising customers a sales path. If your website says buy a side in a way that looks like you own the meat, you have a labeling and commerce problem. The customer owns the live animal first. Then you provide a service.
What would I actually do before I spent money on a building?
I'd call MPES and the county planner in the same week. I'd ask MPES for the current custom livestock slaughterhouse application and the name of the reviewer for my county. I'd ask planning if the parcel allows slaughter. [7]
I'd tour two licensed custom houses as a customer first. Watch the mark, the cooler, the pickup counter. Steal the workflow, not the floor plan.
I'd get three construction numbers and one wastewater number before I ordered a hoist.
I'd read 21 U.S.C. 623 and 9 CFR 303.1 myself. They are short. [1] [2]
CustomExemptPath is an independent publisher, not a law firm and not a service company. If you want the federal document kit, it is $249 one time at /start. It will not talk to Sacramento for you.
Then I'd decide if I am a service business (custom) or a meat brand (inspected). Those are different companies.
Frequently asked questions
Do you need a license for custom exempt slaughter in California?
Yes, if you slaughter livestock that belongs to other people and return the meat. CDFA MPES licenses that work as a custom livestock slaughterhouse. Killing only your own animals for your own household sits under 21 U.S.C. 623 and still does not let you sell the meat. Confirm the current application with MPES. Do not copy another state's packet.
How much does custom exempt slaughter cost in California?
There is no single statewide price. Plants set kill and cut fees. CDFA sets license fees and revises them. Confirm the current license amount with MPES. If you are booking an animal, get written quotes from three licensed plants and ask what hanging weight, cut sheets, and extras are included. Construction and wastewater usually dwarf the license invoice.
How long does custom exempt slaughter take in California?
MPES does not publish a clock you should finance against. Confirm current review expectations with the branch. County land-use and wastewater permits often take longer than the meat license. Livestock owners wait on the plant's rail schedule, which stretches in late fall. No consultant can honestly guarantee an approval date.
Who inspects a custom livestock slaughterhouse in California?
CDFA's Meat, Poultry and Egg Safety Branch licenses and reviews custom livestock slaughterhouses. That is not daily carcass-by-carcass inspection. USDA FSIS still writes the federal custom-exempt rules and may review plants that sit in the federal custom-exempt bucket under Directive 5930.1. Ask MPES which review you are actually in.
Can I slaughter my own steer on my ranch without a license?
21 U.S.C. 623 lets a person slaughter animals of his own raising for household use, household members, and nonpaying guests and employees. That meat still cannot be sold. California still cares about dead-animal movement, inedible handling, and wastewater. Slaughtering other people's animals is licensed custom work, not a backyard favor.
Is custom exempt the same as state inspected?
No. Custom exempt skips carcass-by-carcass inspection and locks the meat to the owner's household. State or federal inspected product carries a mark of inspection and can be sold if you follow that program. 21 U.S.C. 661 is why California can run its own inspection program next to USDA. Custom is a service path, not a sales path.
Does California allow mobile custom slaughter?
CDFA MPES licenses mobile slaughter activity. A truck does not erase the license, the Not for Sale mark, or the sanitation rules. Counties may also want a host-site agreement. Confirm the current mobile packet with MPES before you build a unit. Blood and inedible still have to go somewhere legal.
What does NOT FOR SALE have to look like?
9 CFR 316.16 requires custom prepared carcasses and parts to be marked immediately with the words Not for Sale in letters at least three-eighths inch in height. Keep that identity until the owner takes the meat. Do not hide the words. If you wrap, put the same words on the package that leaves the plant.
Can a restaurant buy custom exempt beef?
No. 21 U.S.C. 623 limits custom meat to the owner's household, household members, and nonpaying guests and employees. A restaurant is commerce. Custom exempt slaughter California product is not a wholesale item. If a chef wants beef to sell on a plate, that animal has to go through inspected slaughter.
Do I register with USDA FSIS or CDFA or both?
Most California custom houses start with a CDFA MPES custom livestock slaughterhouse license. FSIS still owns the federal custom-exempt rule set under 9 CFR 303.1 and may review plants in the federal custom-exempt category. Ask MPES which file they want you in. Sending only a federal grant-of-inspection packet is a common wrong door.
What records does 9 CFR 303.1 require?
9 CFR 303.1 is the federal custom operating rule. It ties the exemption to owner-returned product, sanitation, separation from meat prepared for sale, and records that show the custom work. CDFA will add its own license file on top. Confirm the current MPES list. Keep owner identity, dates, and the Not for Sale trail in a binder you can hand over.
Can I custom slaughter poultry in California on a cattle license?
Do not assume that. Poultry sits under 21 U.S.C. 464, not the livestock clause in 21 U.S.C. 623. CDFA splits livestock custom houses from poultry plants. Ask MPES in writing which species your license covers. Federal bird-count exemptions do not automatically replace a California poultry license. Confirm before you advertise turkey dates.
