FCE & LACF Registration: A Guide for Canned Food Manufacturers

What Are LACF and Acidified Foods?

FDA regulates two categories of thermally processed foods under specific regulations due to the serious botulism risk associated with improper processing:

Low-Acid Canned Foods (LACF)

Defined under 21 CFR §113.3(n), a low-acid canned food is any food (other than alcoholic beverages) with a finished equilibrium pH greater than 4.6 and a water activity (a_w) greater than 0.85, packaged in a hermetically sealed container and heat-treated before or after being placed in the container. Examples include canned vegetables, canned meats, soups, stews, canned beans, and many other shelf-stable products.

The critical concern with LACF is Clostridium botulinum — a spore-forming bacterium whose toxin is one of the most lethal substances known. C. botulinum spores thrive in low-acid, low-oxygen environments (exactly the conditions inside a sealed can). Proper thermal processing (retorting) is the primary control to destroy these spores.

Acidified Foods

Defined under 21 CFR §114.3(b), acidified foods are low-acid foods to which acid(s) or acid food(s) are added to produce a finished equilibrium pH of 4.6 or below and a water activity greater than 0.85. These are packaged in hermetically sealed containers and heat-treated to destroy vegetative microorganisms. Examples include pickled vegetables, pickled peppers, some salsas, and certain canned sauces.

The distinction matters because acidified foods achieve safety through a combination of acid addition and thermal processing, while LACF rely primarily on thermal processing alone. The regulations and process requirements differ accordingly.

FCE Registration: Form FDA 2541

Every establishment that manufactures, processes, or packs LACF or acidified foods in the United States — or exports these products to the U.S. from a foreign country — must register as a Food Canning Establishment (FCE) with FDA. This registration is separate from and in addition to the general food facility registration required under Section 415 of the FD&C Act.

FCE registration is accomplished by submitting Form FDA 2541 (Food Canning Establishment Registration) electronically through FDA's LACF online system. The form requires:

• Establishment name, physical address, and mailing address
• Type of establishment (commercial processor, importer, etc.)
• Type of products packed (LACF, acidified foods, or both)
• Processing methods used (still retort, agitating retort, aseptic, etc.)
• Contact information for the responsible person

Upon acceptance, FDA assigns an FCE number, which is required for all subsequent scheduled process filings. The FCE number is permanent and does not need to be renewed annually, although you must update your registration if any of the information changes.

Foreign establishments must have a U.S. Agent designated before completing their food facility registration with FDA, and should ensure their FCE registration is also in order.

Scheduled Process Filing (Forms 2541a–2541f)

After registering as an FCE, you must file scheduled processes for each product you manufacture. A scheduled process is the thermal treatment (time, temperature, and other critical factors) that has been scientifically determined to achieve commercial sterility (for LACF) or adequate destruction of vegetative organisms (for acidified foods).

Scheduled processes must be established by a recognized process authority — a person or organization with expert knowledge in thermal processing, acidification, and container evaluation. Common process authorities in the United States include university-affiliated food science labs and private consulting firms.

The specific form used depends on the type of processing:

• Form FDA 2541a — for LACF processed by still retort (non-agitating)
• Form FDA 2541b — for LACF processed by agitating retort
• Form FDA 2541c — for LACF processed by hydrostatic retort
• Form FDA 2541d — for products processed by a batch agitating retort where the retort motion stops during the come-up period
• Form FDA 2541e — for products processed by aseptic processing and packaging systems
• Form FDA 2541f — for acidified foods

Each filing must include the specific product name, container size and type, fill weight, headspace, initial temperature, retort temperature, process time, and other critical factors as established by the process authority. Any change to these parameters requires a new process filing.

Better Process Control School (BPCS) Requirement

FDA requires that at least one person at each FCE-registered establishment has successfully completed an FDA-recognized Better Process Control School (BPCS). This training ensures that the person responsible for overseeing thermal processing operations understands the science and regulations governing LACF and acidified food production.

BPCS training covers:

• Principles of thermal processing and acidification
• Equipment operation and monitoring (retorts, closers, acidification systems)
• Container seam evaluation and integrity testing
• Record-keeping requirements under 21 CFR Parts 113 and 114
• Emergency procedures (deviations from scheduled processes)
• FDA regulatory requirements and inspection preparation

BPCS courses are offered by several universities and organizations recognized by FDA, typically as multi-day courses with both classroom and hands-on components. Online/hybrid options have become more widely available since 2020.

The person who completes BPCS is often the plant manager, quality assurance manager, or production supervisor. Foreign manufacturers should ensure that at least one qualified person has current BPCS training before beginning production of LACF or acidified foods for the U.S. market.

Regulatory Framework: 21 CFR Parts 108, 113, and 114

The regulatory framework for LACF and acidified foods is spread across three parts of the Code of Federal Regulations:

21 CFR Part 108 — Emergency Permit Control

Part 108 gives FDA the authority to require a permit for any food manufacturer whose processes are deemed inadequate to protect public health. Under §108.25, all commercial processors of LACF must register their establishments and file scheduled processes. §108.35 provides similar requirements for acidified food processors. Failure to register or file processes subjects the manufacturer to the permit control provisions — effectively, FDA can require a permit before the facility is allowed to operate.

21 CFR Part 113 — Thermally Processed Low-Acid Foods

Part 113 contains the detailed requirements for LACF manufacturing, including:

• Personnel qualifications and training
• Equipment specifications for retorts, recording devices, and temperature measurement
• Production and process controls, including instrument calibration, venting procedures, and processing records
• Container closure requirements and inspection procedures
• Process deviation handling — any deviation from the scheduled process must be evaluated by a qualified person and documented
• Record-keeping — detailed records of each batch, including retort operator logs, temperature recorder charts, and closure inspection records

21 CFR Part 114 — Acidified Foods

Part 114 contains parallel requirements for acidified food manufacturing, with additional emphasis on:

• Acid or acidified food equilibrium pH measurement and control
• Requirements for achieving and maintaining pH 4.6 or below
• Heat treatment sufficient to destroy vegetative cells of microorganisms of public health significance

Common Compliance Mistakes and How to Avoid Them

FDA inspections of LACF and acidified food facilities consistently identify certain recurring violations:

• Failure to file scheduled processes — some facilities register as an FCE but never file the required scheduled processes for their products. Every product-container-process combination must have a filed process.
• Process deviations not properly handled — when the actual process deviates from the scheduled process (e.g., retort temperature drops below the specified minimum), the deviation must be evaluated by a competent authority and fully documented.
• Inadequate container closure inspection — seam inspection for metal cans (or seal inspection for other container types) must be performed at defined frequencies and fully documented.
• Incomplete records — FDA requires detailed records for each batch, including time-temperature recordings, operator logs, and closure inspection results. Missing or incomplete records are a major citation.
• No BPCS-trained person on staff — the BPCS requirement is non-negotiable. FDA will issue observations if no qualified person is available.
• Using the wrong form — filing scheduled processes on the wrong FDA 2541 form variant for the type of retort or process used can result in rejection or delays.

For foreign manufacturers, these compliance requirements apply equally. FDA inspects foreign LACF and acidified food facilities, and violations can result in Import Alerts and detention of shipments. Ensuring that your FCE registration is current, scheduled processes are filed, and records are properly maintained is essential for uninterrupted U.S. market access.
