Answer :
Final answer:
The transfer of pathogens from one food or surface to another is known as cross-contamination. This commonly occurs when microbes from raw foods, like poultry or eggs, contact ready-to-eat foods. Preventing cross-contamination is crucial in food safety.
Explanation:
Understanding Cross-Contamination
The contamination that results from the transfer of pathogens from one food or surface to another is known as cross-contamination. This type of contamination occurs when microbes are transferred from contaminated foods to other foods, often through direct or indirect contact.
For example, if raw chicken is prepared on a cutting board and then the same board is used to chop vegetables without proper cleaning, harmful bacteria like Salmonella can spread to the vegetables. Cross-contamination can occur with various types of foods, especially when dealing with raw meats, eggs, and ready-to-eat items such as salads or sandwiches.
Other terms mentioned, such as physical contamination (involving foreign objects like hair or glass), chemical contamination (involving harmful chemicals), and transfer contamination (less commonly used), do not specifically describe the transfer of pathogens via food contact.
Preventing Cross-Contamination
- Use separate cutting boards for raw meats and vegetables.
- Always wash hands, utensils, and surfaces after handling raw foods.
- Store raw foods on lower shelves in the refrigerator to prevent dripping onto other foods.
