Definition: Cross-contamination is the transfer of harmful bacteria, viruses, or other microorganisms from one substance or object to another, resulting in potential contamination and foodborne illnesses. This can occur in various settings, especially in food preparation and handling environments.
Common pathways for cross-contamination can be from direct contact (contaminated foods or surfaces touch other foods or surfaces), hands, utensils, drips & splash (liquids from raw foods, liquids, etc), or clothing.
What Causes Cross-Contamination?
Supplies in offices, bedsheets in hotels, and door handlels at event centers are just some examples.
The transfer of harmful bacteria and microorganisms from one surface, object, or food can be narrow down to a set of reasons.
Improper Handling of Raw Foods – Raw meat, poultry, seafood, and eggs can contain harmful bacteria that can be transferred to other foods if not handled correctly.
Poor Hand Hygiene – Not washing hands thoroughly after handling raw foods, using the restroom, or touching other contaminated surfaces can lead to the spread of microorganisms.
Inadequate Cleaning of Surfaces and Equipment – Guarantee the spread of bacteria by using the same cutting boards, knives, or utensils for any raw and ready-to-eat foods.
Incorrect Food Storage – Storing raw meat above ready-to-eat foods in the refrigerator can cause juices to drip and contaminate other items.
Inadequate Cooking and Reheating – Using cleaning chemicals inappropriately or not rinsing them off surfaces can leave residues that contaminate food.
Preventing cross-contamination involves maintaining strict hygiene practices, thorough cleaning, proper food storage, and careful handling of raw and cooked foods. By addressing these causes, the risk of foodborne illnesses can be minimized.

How To Prevent Cross-Contamination
