Most packaged foods fall under FDA’s Current Good Manufacturing Practice (CGMP) and Preventive Controls rules, while meat, poultry, and some egg products are overseen by USDA. This guide walks through the practical steps U.S. plants follow to turn ingredients into safe, high-quality finished goods—highlighting controls you should build into each stage of the food manufacturing process. FDA Preventive Controls for Human Food (FSMA)
Regulatory backbone: CGMPs shape the food manufacturing process
CGMPs are the everyday rules that underpin the food manufacturing process—governing people, plant design, sanitation, process controls, and records. They’re the baseline practices every facility must implement, even before hazard-specific preventive controls come into play. If you’re designing or auditing any part of the food manufacturing process, start by aligning with CGMP Subpart B and then layer on hazard analysis, monitoring, and verification. FDA overview: CGMPs (21 CFR Part 117)
Supplier approval: first gate in the food manufacturing process
A robust supplier program is a non-negotiable early step in the food manufacturing process. You’ll assess supplier risk, review COAs, set specifications, and verify that any hazards controlled before receipt are truly managed. For many plants, supply-chain-applied controls and approval criteria are documented as part of the Food Safety Plan, with ongoing verification such as audits or sampling. FDA: Preventive Controls & Supply-Chain Program
Receiving and incoming inspection
When ingredients arrive, the food manufacturing process requires checks for integrity, temperature (if perishable), labeling, pest evidence, and compliance with specs. CGMPs also require qualified personnel and hygienic handling to prevent contamination during unloading. Your receiving SOPs should spell out acceptance criteria, sealing/tamper checks, and “hold” procedures for nonconforming lots. eCFR: 21 CFR 117 Subpart B (CGMP)
Storage and inventory control
Proper storage—ambient, refrigerated, or frozen—is central to the food manufacturing process. Use FIFO/FEFO rotation, map temperature zones, and separate raw and ready-to-eat (RTE) ingredients to avoid cross-contamination. Basic food safety principles also apply: keep cold foods cold, prevent cross-contact, and maintain clean, dry spaces to minimize microbial growth. CDC: Four Steps to Food Safety
Formulation and allergen management
Formulation controls make the food manufacturing process repeatable and safe. U.S. labels must declare “major food allergens,” now including sesame as the ninth major allergen. Control points here include verified recipes, scaled batching, dedicated utensils, validated changeovers, and label verification to prevent undeclared allergens—one of the most common recall causes. FDA Guidance: Food Allergen Labeling (Edition 5)
Produce and water contact steps (where relevant)
If your food manufacturing process includes fresh produce steps (washing, trimming, minimal processing), integrate agricultural water quality and sanitation controls consistent with the Produce Safety Rule. Even in mixed facilities, attention to water source, sanitizer concentrations, and drip/dry zones reduces cross-contamination risks downstream. FDA: Produce Safety Rule (21 CFR Part 112)
Comminution, mixing, and emulsification
Grinding, mixing, and emulsifying introduce large surface areas and intense contact among ingredients—so this stage of the food manufacturing process needs tight sanitation frequency, foreign-material controls, and allergen changeover verification. Preventive controls should address foreseeable hazards, with monitoring, corrective actions, and verification documented in the Food Safety Plan. FDA Draft Guidance: Hazard Analysis & Preventive Controls
Thermal processing and lethality
For low-acid canned foods and acidified foods, specific federal rules govern the food manufacturing process, including scheduled processes, thermal validation, and filing/registration. Beyond canning, many foods rely on pasteurization or validated kill-steps to reduce pathogens to safe levels. Recordkeeping and process deviations must be handled per your plan.

Define what gets cleaned, how, by whom, how often, and how effectiveness is verified (ATP, visual, micro). CIP/SIP systems should be validated for soil loads and “worst-case” conditions, with pre-op inspections and post-sanitation swabbing built into routines. USDA FSIS: Sanitation SOPs Guidance
Allergen changeovers and label verification
Because undeclared allergens drive many recalls, this checkpoint in the food manufacturing process demands rigorous label control, physical or procedural segregation, validated cleaning between allergen runs, and documented label reviews. Sesame has been a major focus since 2023, and manufacturers must account for it in both processing and labeling steps. FDA: FASTER Act — Sesame as 9th Major Allergen
Packaging and food contact materials
Primary packaging must be safe and suitable for its intended use in the food manufacturing process. In the U.S., many food-contact substances are authorized through FDA’s Food Contact Notification (FCN) program or specific regulations. Packaging changes should trigger a regulatory review to confirm the material is cleared for the food type, use level, and temperature. FDA: How FDA Regulates Food-Contact Substances
Coding, traceability, and recall readiness
Effective lot coding and end-to-end traceability make the food manufacturing process more resilient when issues arise. FDA’s Food Traceability Rule sets additional recordkeeping for certain high-risk foods, while all FDA-regulated firms should maintain recall plans with defined roles, contact lists, and mock recall drills to verify speed and accuracy. FDA: Food Traceability Final Rule (FSMA 204)
Quality testing, verification, and release
Before release, the food manufacturing process typically includes finished-product checks (sensory, label, net weight, micro/chem as applicable) and review of critical records (monitoring, deviations, corrective actions). Where microbiological testing is used, validated methods and accredited labs or established in-house programs are key to defensible decisions. FDA: Bacteriological Analytical Manual (BAM)
Distribution and the sanitary transportation rule
The food manufacturing process doesn’t end at the dock. Shippers, loaders, carriers, and receivers must prevent contamination during transit by controlling temperatures, protecting against cross-contamination, and cleaning conveyances. Contracts and records should define responsibilities, including temperature monitoring and corrective actions. FDA: Sanitary Transportation Rule
Sustainability, waste, and by-product management
Modern plants build sustainability into the food manufacturing process—reducing water and energy use, diverting organic by-products, and minimizing landfill waste. EPA provides tools for preventing and diverting wasted food, along with resources on anaerobic digestion and composting for industrial generators. EPA: Sustainable Management of Food
Worker safety and training
People make the food manufacturing process work. Beyond food safety training, plants must protect workers from hazards such as chemicals (e.g., ammonia), machines, ergonomic stresses, and slips/falls. Align your EHS program with OSHA guidance and link it to your food safety culture—fatigued or unsafe teams make quality and safety errors. OSHA: Food Processing Industry
Digitalization and smart manufacturing
Industry 4.0 tools—real-time sensors, MES/SCADA, data lakes, and predictive maintenance—can streamline the food manufacturing process by improving OEE, cutting changeover time, and strengthening traceability. As you digitize, consider cybersecurity, interoperability, and measurement science so data actually improves decisions on the floor. NIST: Smart Manufacturing
Capability building for small and mid-size plants
Smaller processors can accelerate their food manufacturing process maturity with external help on food safety, quality systems, and operations. The NIST MEP National Network offers support—training, gap assessments, and implementation—to raise compliance and performance while keeping costs in check. NIST MEP: Food Industry Services
Recalls and continuous improvement
Even with strong controls, the food manufacturing process must be “recall-ready.” Map your recall strategy, reporting chains, and documentation in advance; conduct mock recalls and trace exercises; and close CAPAs quickly. FDA’s recall framework and guidance outline expectations, timelines, and effective communication practices. FDA Guidance: Initiation of Voluntary Recalls
Final thought
The most successful food manufacturing process is both compliant and competitive: CGMPs as the daily discipline, preventive controls as your risk engine, smart tech for speed and visibility, and a culture that treats quality and safety as everyone’s job. Use this guide as a blueprint, then tailor each control to your hazards, equipment, people, and brand promise. FDA: FSMA FAQs
