Operational Methods

Operational methods are the written, everyday procedures a food business follows to receive, store, handle, make, pack and ship food, so each step is done the same safe way every time.

  • Food safety
  • Food safety programs

Operational methods are the how-to layer of a food safety program: the documented practices for each stage of production, from receiving and storing ingredients to mixing, baking, packing and shipping. In federal CGMP rules, most of these expectations sit under processes and controls. That section calls for inspecting and segregating raw materials, keeping equipment and containers in good condition, controlling temperature, protecting food from metal and other extraneous material, and labeling rework. Facilities covered by the preventive controls rule also write specific controls where their hazard analysis shows they are needed.

Food safety depends on routine steps being done correctly every time. Written methods turn broad requirements into specific actions staff can follow, check and record. Federal rules require preventive controls to be written and, for process controls, to state the parameters and the minimum or maximum values that must be met. Monitoring then shows whether controls are operating as intended, and verification confirms the whole system works.

Key facts

Written requirement
Preventive controls must be written (21 CFR 117.135(b))

In a bakery or commercial kitchen

  • Write step-by-step SOPs for receiving, storage, mixing, baking and packing, and train every staff member on them
  • Set measurable limits, such as bake temperature or a safe moisture level for dry mixes, and record checks
  • Inspect and segregate incoming ingredients before releasing them to production
  • Label product set aside for rework and track where it is used
  • Protect finished goods from allergen cross-contact and from anything that could drip or drain onto them

For home and cottage bakers

  • Write your process down, including oven temperature, bake time and cooling steps, so every batch is made the same way
  • Keep separate, labeled scoops and tools for allergen ingredients such as nuts to limit cross-contact
