A food safety plan is a written document that identifies the biological, chemical, and physical hazards in a food operation, and spells out the preventive controls, monitoring procedures, and corrective actions used to keep those hazards from reaching consumers. Under FSMA's Preventive Controls rule, most food manufacturers are legally required to have one, reviewed and re-analyzed at least every three years or whenever a significant change occurs.
What a food safety plan must include
A compliant food safety plan (per 21 CFR 117 Subpart C) has five core components:
- Hazard analysis — identifying biological, chemical, physical, and (where relevant) radiological hazards at each processing step.
- Preventive controls — process controls, sanitation controls, allergen controls, and supply-chain controls that address the hazards identified.
- Monitoring procedures — how and how often each preventive control is checked.
- Corrective action procedures — what happens when a control fails or a monitoring result falls outside limits.
- Verification activities — calibration, review of monitoring records, and periodic reassessment that confirm the plan is actually working.
Food safety plan vs. HACCP plan
A HACCP plan is the older, narrower model built around identifying Critical Control Points (CCPs). A food safety plan, as required under FSMA, is broader — it still includes hazard analysis, but preventive controls apply more broadly than just at CCPs, and it explicitly requires a written recall plan and environmental monitoring where applicable. Facilities already USDA-regulated typically still operate under HACCP; FDA-regulated facilities operate under the FSMA food safety plan model. Many manufacturers maintain both frameworks side by side depending on which products or markets they serve. For a step-by-step walkthrough of the older framework, see our guide on how to create a HACCP plan, which also covers this exact distinction in more detail.
Who needs one
Any FDA-regulated food facility required to register under the Food Safety Modernization Act needs a written food safety plan, with limited exemptions for qualified facilities under the small business/very small business provisions (which instead follow simplified modified requirements). Retail-only operations and some low-risk activities are generally excluded.
Building and maintaining a food safety plan with AI
Because a food safety plan has to stay current with ingredient changes, new suppliers, and process changes, manual upkeep is one of the most common places small and mid-size manufacturers fall behind. IONI's AI-assisted food safety plan builder pulls in your existing recipes, suppliers, and process data to draft hazard analyses and preventive controls, then flags sections that need re-review when something upstream changes — cutting the rebuild-from-scratch cycle that a lot of smaller teams currently do by hand every three years.

Frequently asked questions
Is a food safety plan the same as a HACCP plan?
They're related but not identical. A food safety plan (FSMA/21 CFR 117) is the newer, broader FDA requirement; HACCP is the older model focused specifically on Critical Control Points and is still the primary framework for USDA-regulated meat and poultry facilities.
How often does a food safety plan need to be updated?
At minimum every three years, and immediately whenever there's a significant change to ingredients, suppliers, processes, or packaging that could introduce a new hazard.
Who has to sign off on a food safety plan?
It must be prepared, or its preparation overseen, by a Preventive Controls Qualified Individual (PCQI) who has completed FDA-recognized training or has equivalent job experience.
