Food safety compliance in the United States is not one rule. It is a stack of requirements from different sources: federal law, state and local agencies, voluntary global schemes and the private audit demands of your biggest customers. Plants that treat them as separate projects end up with duplicate paperwork and conflicting procedures. Plants that understand how the layers connect can build one strong system that satisfies all of them.
This guide maps the landscape for food manufacturers: who regulates what, what FSMA requires in practice, how GFSI schemes such as SQF and BRCGS fit in, and how to build a compliance program that holds up under any auditor. For the basics of why this matters, see our overview of why food safety and sanitation are important and our food safety hub.
The four layers of food safety compliance
| Layer | Who sets it | Mandatory? | Examples |
| 1. Federal law | FDA, USDA | Yes | FSMA rules, USDA HACCP and sanitation rules |
| 2. State and local | State agriculture and health departments | Yes | Licensing, inspections, local codes |
| 3. GFSI recognized schemes | Scheme owners such as SQF Institute and BRCGS | Voluntary, but often demanded | SQF, BRCGS, FSSC 22000, and others |
| 4. Customer requirements | Retailers, brands, food service buyers | By contract | Supplier audits, specifications, extra testing |
The first two layers are the law. The second two are commercial, but they often feel just as binding because losing a customer can hurt as much as a regulatory action.
Layer 1: Federal requirements
FDA and FSMA
The FDA regulates most packaged and processed foods. The Food Safety Modernization Act (FSMA) shifted the focus from reacting to contamination to preventing it. For manufacturers of human food, the key pieces include:
- Current good manufacturing practices (cGMPs): basic expectations for personnel, plant and grounds, sanitary operations, equipment and processes.
- Hazard analysis and risk-based preventive controls: a written food safety plan, prepared or overseen by a Preventive Controls Qualified Individual (PCQI).
- Preventive controls: process controls, allergen controls, sanitation controls and supply chain controls, along with monitoring, corrective actions, verification and records.
- Recall plan: a written plan for how you would handle a recall.
- Supplier programs: approving and verifying suppliers where hazards are controlled upstream.
- Food traceability requirements: additional recordkeeping for foods on the FDA’s Food Traceability List. The compliance date has been extended, so check the FDA site for the current date.
Sanitation controls are a named category of preventive control. That means cleaning and sanitizing programs are part of your legal food safety plan, not an extra. Learn more in our guide to what role regular cleaning plays in food laws.
USDA FSIS
The USDA Food Safety and Inspection Service regulates meat, poultry and processed egg products. Plants under FSIS inspection follow their own HACCP and sanitation requirements, including written sanitation standard operating procedures. If you make products that fall under both agencies, you need to know which rules apply to each product line.
Layer 2: State and local
State agriculture and health departments license facilities, inspect them and enforce local codes. Requirements vary, so keep a current list of the agencies that oversee your plant and make sure each one has an up to date contact on file.
Layer 3: GFSI recognized schemes
The Global Food Safety Initiative (GFSI) does not certify plants. It benchmarks food safety certification schemes, and a scheme that meets the benchmark is called GFSI recognized. You can read more at the GFSI website. Common examples include:
- SQF: widely used in North America. See our SQF certification page.
- BRCGS: popular with retailers and brands, especially those with international supply chains. See our BRC certification page.
- FSSC 22000, PrimusGFS, IFS: used in various sectors and regions.
Certification is voluntary under the law, but many customers make it a condition of doing business. If you are unsure which to choose, our BRC vs SQF guide compares the two most common options in the US.
Layer 4: Customer requirements
Large buyers add their own expectations on top of the law and the scheme. These can include:
- Supplier approval questionnaires and onsite audits
- Specifications for ingredients, packaging and labeling
- Extra environmental or allergen testing
- Notification and recall response timelines
- Specific certification requirements
The best way to handle these is to log every customer requirement in one register, map each to an existing procedure, and only add new work where there is a real gap.
How the layers overlap
The good news is that they share the same foundations. A HACCP-based food safety plan, written procedures, trained people, monitoring, corrective action and verification records satisfy the core of FSMA, SQF, BRCGS and most customer audits. The differences are in format, depth and audit style.
That is why a single, well-built system beats separate programs. You write once, audit many ways.
Building a compliance program in seven steps
- Map your obligations. List which agencies, schemes and customers apply to each product and site.
- Appoint accountable people. Name a PCQI or equivalent, an SQF practitioner if you pursue SQF, and a senior sponsor with budget authority.
- Complete the hazard analysis. Document biological, chemical, physical and allergen hazards and the controls for each.
- Write the preventive controls. Include process, allergen, sanitation and supply chain controls with monitoring and corrective actions.
- Build your sanitation program. Cleaning schedules, procedures, chemical control and verification are central. Start with our master sanitation schedule and SSOP guide.
- Verify and test. Use environmental monitoring, product testing, internal audits and mock recalls. See environmental monitoring and ATP testing.
- Audit yourself on a schedule. Combine internal audits with outside reviews. Our guide to types of food safety audits shows how.
Common compliance gaps we see
- Food safety plans that were written once and never reassessed
- Sanitation treated as housekeeping instead of a preventive control
- Records that are complete on paper but not truly verified
- Training that is recorded but not tied to job tasks
- No documented process for tracking customer requirements
- Mock recalls that are never timed or challenged
Many of these also appear in audit reports. Our article on common SQF audit non-conformances goes through them in detail, and our guide on how to verify food safety and sanitation compliance covers verification methods.
Who should help you build the program?
Most plants combine internal QA, outside expertise and reliable sanitation labor. If you are not sure how to divide the work, read food safety consultant vs. contract sanitation vs. in-house QA. For qualifications to look for in people, see PCQI, HACCP and SQF practitioner pathways. If you are budgeting for a scheme, our SQF certification cost and timeline guide helps.

Frequently Asked Questions
What is food safety compliance?
It means meeting the legal, scheme and customer requirements that apply to making safe food, including written plans, controls, monitoring, records and audits.
Is FSMA compliance mandatory?
Yes, for facilities covered by FDA rules. Some small businesses and product types have modified requirements or exemptions, so confirm what applies to you.
Is SQF or BRCGS certification required by law?
No. They are voluntary, but many retailers and food service buyers require them from suppliers.
Do I need a PCQI?
For facilities subject to the FDA preventive controls rule, the food safety plan must be prepared or overseen by a PCQI. See our guide on becoming a food safety specialist for training options.
How often should a food safety plan be reviewed?
At least periodically and whenever a process, ingredient, equipment or hazard information changes. Many plants also schedule a full annual review.
