Question

Define the term cross-contamination. Also give two ways through which it happens.

Hint:

To prevent cross-contamination, always use separate utensils and cutting boards for raw and cooked foods and store food properly.

Answer 1

Cross-contamination is the unintentional transfer of hazardous microorganisms or allergens between food items. This transfer typically occurs during food handling or preservation processes, and can result in foodborne diseases.
Cross-contamination can occur via the following methods:
1. Shared Utensils/Surfaces: Employing the same knife or cutting board for uncooked meat and produce without sanitization between uses can facilitate bacterial transmission.
2. Inadequate Storage Practices: Placing uncooked meat above ready-to-eat food items in refrigeration units allows meat juices to potentially drip onto other foods, causing contamination.
