Complex Processes

Failure to adequately control food product temperature is the one factor most commonly associated with food-borne illness. Foods prepared in large volumes or in advance for next-day service usually follow an extended process flow. These foods are likely to pass through the temperature danger zone several times. The key in managing the operational steps within the process is to minimize the time foods are at unsafe temperatures.

In some cases, a variety of foods and ingredients that require extensive employee product preparation may be part of the process. A sound food safety management system will incorporate standard operating procedures for personal hygiene
and cross-contamination prevention throughout the flow of the food.

Before you set up a management system for your operational steps, there are several factors you should consider. Multiple-step processes require proper equipment and facilities. Your equipment needs to be designed to handle the volume
of food you plan to prepare. For example, if you use a process that requires the cooling of hot food, you must provide equipment that will adequately and efficiently lower the food temperature as quickly as possible. If you find that a recipe
is too hard to safely prepare, you may want to consider purchasing pre-prepared items from a reputable source.

To assist food establishments in applying HACCP principles at the retail level, the FDA has issued a draft document entitled Managing Food Safety: A HACCP Principles Guide for Operators of Food Service, Retail Food Stores, and Other Food Establishments at the Retail Level. This document is available from the FDA and can be found on the FDA Web page at http://vm.cfsan.fda.gov/~ear/retail

There are seven steps in the flow of food that we will take a closer look at in regard to food safety including possible contaminates at each stage and ways to avoid contamination at each stage. In order, we’ll look at:

1. Purchasing and receiving.
2. Storing.
3. Preparing.
4. Cooking.
5. Serving and holding.
6. Cooling.
7. Reheating.

There are multiple hazards at, and specific preventative measures for, each step.
