Final answer:
Cross-contamination is the transfer of pathogenic bacteria from one surface to another, particularly important in food safety. To prevent it, separate raw and cooked food handling, and ensure thorough cleaning. Proper hygiene practices are crucial to avoid foodborne illnesses.
Explanation:
Understanding Cross-Contamination
The transfer of pathogenic bacteria from one surface to another is known as cross-contamination. This phenomenon is particularly significant in food safety, where it can lead to foodborne illnesses. Cross-contamination occurs when harmful microbes are transferred from raw foods, such as eggs, poultry, or meat, to ready-to-eat foods, like vegetables or bread.
Examples and Prevention
For instance, if a cutting board is used to prepare raw chicken, and then the same board is used without proper cleaning for cutting salad, pathogens like Salmonella can contaminate the salad. To prevent cross-contamination, always use separate utensils and surfaces for raw and cooked foods, and ensure thorough cleaning in between preparations.
- Always wash hands, surfaces, and equipment after handling raw foods.
- Store raw foods separately from cooked foods in the refrigerator.
- Use different cutting boards for raw meats and produce.
