Food Safety
What are operational methods?

Operational methods address the practices that personnel in a food manufacturing facility follow to prevent food safety issues. They provide the guidelines for a program that will reduce the risk of cross-contamination.

Cross-contamination can occur when employees move from one area of production to another, or when materials and utensils are not color-coded and segregated, labels are not accurate, or the rework procedure is not followed correctly. The FDA guidelines for Good Manufacturing Practices (GMP’s) require that all food received by manufacturers be protected from contamination.1 The program should include the following:2

  • Label control
  • Rework handling
  • Identification and handling of scoops, containers, and utensils
  • Transfer and handling of materials

Bakeries face cross-contamination from allergens, employees, and mislabeled items. Implementing operational methods will reduce risks at every stage of the manufacturing process, from receiving to shipping. Operational methods should be included as part of a Hazard Analysis Critical Control Point food safety program.

Operational methods can help a bakery with food safety guidelines.

Origin

In 1969, the FDA designed the current GMP regulations to help ensure the safe and sanitary manufacturing, processing, and holding of food for human consumption.3

Regulatory compliance

Operational methods can be found under the FDA’s guidance in 21 CFR part 110, entitled “Current Good Manufacturing Practice in Manufacturing, Packing, or Holding for Human Food.”4

Relevance

When establishing operational methods, focus on the four key areas: label control, rework handling, identification and handling of utensils, and transfer and handling of materials. Putting the methods in place will reduce the risks associated with cross-contamination.

Label control

Ingredients used in a food product must be declared on the label. During manufacturing, a label control program will cover the following:1

  • Confirmation of correct labels upon receipt
  • Label confirmation at time of use
  • Security measures for obsolete labels

Rework

Rework is defined as a product that is unadulterated food that has been removed from processing; it is sanitary and suitable for use as food.[5]  Examples of rework are pastry scrap, day-old bread used in the production of croutons or stuffing, or dough. It is important that only like products are used together to avoid cross-contamination or introduction of allergens. Rework should be included in a traceability program.

Identification and handling of scoops, containers, and utensils

Having a system in place to ensure that the correct scoops, containers, and utensils are used will greatly reduce the risk of product contamination. Color-coding can be used to identify tools with the type of use in the bakery.

Examples of  color-coding for containers and utensils:1

  • White: Ingredient (non-allergen)
  • Gray: Trash
  • Yellow: Sanitation
  • Blue: Recycling
  • Green: Allergen

Transfer and handling of materials

Moving materials around a manufacturing facility can allow opportunities for contamination. Materials such as ingredients, work-in-progress, and finished goods should be part of an operational method procedure.

Stored materials may need to be sampled by QC before use in manufacturing. Sampling of materials must be done in accordance with a defined sampling protocol that includes sanitation of sampling tools, marking of compromised containers, and resealing.1 The most common storage containers are bags, boxes, pails, and drums. Protocols should be established for each type of container.
