How Color Coding Works in Food Processing?

Where do we often see color coding scheme?

During travels. The traffic lights are color coded. Green for go, orange for ready, and red for stop.

Vehicle plates. Green for private vehicles, yellow for commuters, red for government owned and blue for consuls.

Schools. Not really  a color coding scheme but every school tend to establish their color identity using student uniforms.

Color coding can also be use effectively in food processing. Here are some examples.

1) Different uniform colors. Brown for receiving, green for preparation, yellow for cooking, red for packing, blue for warehouse and maroon for office workers. As a rule of thumb any personnel from receiving area should not go to preparation. So there should be no brown color in group of greens. It will be very easy to pinpoint whenever someone tries to violate the rule.

2) Color coded knives, ladles, spoons and other utensils. Each can be prominently labeled so carrying from area to another area could be prevented. However, someone can easily tamper, remove or cover it and do the untoward. Color coded utensils is easier to monitor.

3) Color coded floor tiles. If items one and two are color coded, then it not surprising if the floor tiles of each processing sections are color coded too.

Its main purpose is to prevent cross-contamination.

4) Ingredient containers. Green for safe chemicals, orange for toxic and red for extremely poisonous. Or, it can be green for natural ingredients and orange for artificial.

5) Product labeling. Red for pork and beef,  yellow for pineapple and mango, orange for papaya and oranges and brown for chico.
