High-Risk Contamination Source?

Equipment like meat slicers or cutting boards can harbor bacteria if not properly cleaned and sanitized.

Safe Vertical Food Storage?

Cooked chicken stored above raw ground beef prevents potential drips of raw juices onto ready-to-eat food.

Cause of Cross-Contamination?

Cross-contamination occurs when pathogens are transferred from one surface or food to another, often due to poor hand hygiene.

Main Way to Cross-Contaminate?

Transferring pathogens directly from one food to another, especially from raw to cooked or ready-to-eat foods.

Study Notes

Cross Contamination Overview

  • Serious bacterial contamination is most likely caused by a meat-slicer or cutting board.
  • Proper vertical food storage places cooked chicken above raw ground beef to minimize contamination risks.

Causes of Cross Contamination

  • Cross contamination can happen when:
    • Disposable gloves are not changed frequently.
    • Hands are not washed as required.
    • Utensils are not washed and sanitized between uses.

Major Pathways of Cross Contamination

  • Main methods of cross contamination include:
    • Food to food contact
    • People to food contact
    • Equipment to food contact

Examples of Food Types

  • Ready-to-eat food example: A donut is considered ready-to-eat.

Common Contamination Sources

  • Hands are the most common means by which food handlers contaminate food and surfaces.

Food Storage Regulations

  • Coconino County Food Code mandates that all raw animal foods must be separated from ready-to-eat foods.
  • Raw chicken should NOT be stored above ground beef to prevent cross contamination.

Food Storage Practices

  • Foods should always be stored at least six inches off the floor to avoid contamination.
  • The "Bare Hand Contact" rule applies to all employees, not just those who have used the restroom.
