Do I need FDA registration to start a cannery?

Yes. Any commercial acidified or low-acid canned food processor must register the facility with the FDA to receive a Food Canning Establishment (FCE) number and file each scheduled process to get a Submission Identifier (SID). You also renew your general FDA facility registration every even-numbered year. No shelf-stable product should ship without a filed process behind it.

What is Better Process Control School and is it required?

Better Process Control School is a certification course, offered by universities like UC Davis and Purdue, covering thermal processing, acidification, container closures, and recordkeeping. At least one supervisor per shift at an acidified or low-acid cannery must hold this certification. Budget roughly $600 to $1,000 per person plus travel, and plan to recertify.

What is the difference between acidified and low-acid canned foods?

Acidified foods reach an equilibrium pH of 4.6 or below through added acid and are governed by 21 CFR 114; safety hinges on pH control. Low-acid canned foods have pH above 4.6 and water activity above 0.85, fall under 21 CFR 113, and must be pressure-sterilized (retorted) to a scheduled process. Low-acid is the higher-risk, higher-cost category.

What is a scheduled process and why can't I design my own?

A scheduled process is the exact combination of time, temperature, pH, fill weight, and container specs that makes your product safe. It must be established by a qualified process authority, not the operator, because an error in a low-acid food can allow botulinum growth. The filed scheduled process is the legal backbone of your cannery.

How much does it cost to start a commercial cannery?

Costs vary widely, but plan for process-authority filing fees, Better Process Control School tuition, state plan review and licensing, equipment (retort or hot-fill line, pH meter, closure tools), and lab testing. Beyond startup, your unit economics depend on produce yield after shrink, packaging cost per jar, and energy, so cost a batch carefully before committing to accounts.

How to Start a Commercial Cannery Business (FDA Rules)

# How to Start a Commercial Cannery Business (FDA Rules)

Canning is one of the most heavily regulated corners of food production, and for a reason: a single processing error in a shelf-stable low-acid food can grow Clostridium botulinum. The FDA treats commercial canning differently from almost any other food business. You cannot just rent a kitchen and start filling jars. If you want to sell shelf-stable canned goods across state lines, you have to register your process with the federal government, prove it was designed by a qualified authority, and keep records that survive an inspection. This guide lays out the real path, the credentials you need, and the numbers that decide whether the business works.

Acidified vs. Low-Acid: Know Which Rule You Live Under

The first thing to nail down is which category your product falls in, because it determines the entire regulatory burden.

Acidified foods (21 CFR 114) are low-acid foods to which acid or acid foods are added to bring the equilibrium pH to 4.6 or below. Think pickles, salsa, relishes, marinated vegetables, hot sauce with vegetable base. Below pH 4.6, botulinum spores cannot grow, so the process is built around controlling and verifying pH.

Low-acid canned foods (21 CFR 113) have a finished equilibrium pH above 4.6 and a water activity above 0.85 - green beans, corn, soups, meats, most vegetables. These must be sterilized under pressure (retorted) to a scheduled process that destroys botulinum spores. This is the higher-risk, higher-cost category.

Borderline products matter. A salsa at pH 4.5 is acidified; the same recipe drifting to pH 4.8 is suddenly a low-acid food under a far stricter rule. Your process authority decides this, not your taste buds.

The Non-Negotiable Credentials and Filings

Here is where most first-timers underestimate the work. To legally produce acidified or low-acid canned foods commercially, you need all of the following:

1. Better Process Control School (BPCS). At least one supervisor per shift must be certified by completing a BPCS course, offered by universities like UC Davis, Purdue, and others. Courses run a few days and cover thermal processing, acidification, container closures, and recordkeeping. Budget roughly $600-$1,000 per person plus travel.

2. A filed scheduled process from a process authority. You cannot design your own kill step. A qualified process authority (a thermal-processing expert) establishes the scheduled process - the exact time, temperature, pH, fill weight, and container specs that make your product safe. This is the legal backbone of your operation.

3. FCE and SID/FPS numbers. You must register your establishment with the FDA to get a Food Canning Establishment (FCE) number, then submit each scheduled process to receive a Submission Identifier (SID). No product ships without a filed process behind it. Filing is done through the FDA's electronic system and is free, but you file per product-container-process combination.

4. FDA facility registration under the Bioterrorism Act, renewed every even-numbered year.

5. State licensing and inspection. Most states layer their own cannery or food-processing license on top of the federal rules, with plan review and periodic inspection.

Skipping any of these is not a shortcut - it is the difference between a legal cannery and a recall waiting to happen.

Records the FDA Actually Checks

Inspection is document-driven. The FDA verifies that every batch was made to the filed scheduled process and that deviations were caught and handled. At minimum you must keep, for the retention period the rule requires:

Scheduled process records tied to your filed FCE/SID numbers, with any deviation flagged and evaluated.
Retort or thermal process records for low-acid foods: come-up time, process temperature, hold time, and cooling, logged per batch with any critical-control-point deviation documented.
pH and water activity verification for acidified foods, measured on the finished equilibrated product per batch, with corrective action recorded when a reading drifts.
Container closure examinations at set intervals - seam teardown records for cans, torque and vacuum for jars.
Coding and traceability so any batch can be pulled from distribution.

A missing retort chart or an unexplained pH deviation is exactly what turns a routine inspection into a warning letter.

The Economics: Costing a Batch

Regulation aside, the business only works if the unit economics do. Canning is a low-margin, volume game unless you have a premium product. Build your cost per jar from every input:

Produce/raw material, including shrink - trimming, peeling, and cooking loss can remove 20-40% of intake weight. If you buy 100 lbs of tomatoes and yield 62 lbs of finished salsa, your effective ingredient cost is far higher than the sticker.
Jars, lids, and labels - often $0.40-$1.00+ per unit at small-batch volumes, and the single biggest cost after produce for many products.
Energy - retorting and hot-fill are energy-intensive; steam and water are real line items.
Labor, including the certified supervisor's time and the recordkeeping burden.
Overhead and compliance - process authority filings, BPCS recertification, lab testing, insurance.

A useful rule of thumb: your fully loaded cost per jar plus a healthy margin has to clear the price your channel will bear. Farmers-market direct pricing tolerates $8-$12 jars; wholesale into retail often demands a landed cost under 40-50% of shelf price. Know your yield per batch and your true cost per jar before you commit to a co-pack or a retail account.

A Realistic Startup Sequence

1. Develop and stabilize the recipe, then have a process authority test and file the scheduled process. 2. Send at least one supervisor to Better Process Control School. 3. Register the facility with the FDA, obtain your FCE number, and file each product's SID. 4. Secure state licensing and pass plan review. 5. Stand up your recordkeeping system before the first production run - retort logs, pH logs, closure checks. 6. Run, log every batch, and hold product until records confirm the process was met.

Keep Your Records Audit-Ready From Day One

The fastest way to fail an inspection is a good process with sloppy paperwork. The Acidified & Low-Acid Cannery Compliance Kit is built around exactly the records the FDA and state inspectors ask for: a scheduled-process log tied to your filed FCE/SID numbers with deviation alerts, a retort and thermal-process record capturing come-up, hold, and cool with CCP deviations, a pH and water-activity verification log by batch, a batch cost and yield calculator that accounts for produce shrink and packaging, and a process-authority and BPCS credential tracker so certifications never lapse. If you are still deciding which category you fall under, the free guide walks through the acidified-versus-low-acid decision before you invest in the full kit.

Canning rewards discipline. Get the scheduled process filed, get one person through Better Process Control School, log every batch against the filed numbers, and cost your product honestly. Do that and you have a defensible, shelf-stable business the FDA will sign off on.
