Final answer:
Cross-contamination transfers pathogens from one food source or surface to another during food preparation. This can occur through raw food contact, unwashed hands, or contaminated utensils and surfaces. Preventing this is essential for maintaining food safety.
Explanation:
Understanding Cross-Contamination
When cross-contamination occurs in food preparation, it typically involves the transfer of pathogens from one source to another. This can happen through various means, such as:
- Raw foods: Foods like raw eggs, poultry, and meat often harbor bacteria (e.g., Salmonella) that can contaminate other foods if they come into contact.
- Unwashed hands: If a person prepares food without washing their hands after handling raw foods, they can transfer these harmful pathogens to ready-to-eat foods.
- Preparation areas: Using cutting boards, utensils, or countertops that have not been cleaned properly after preparing contaminated foods may also lead to cross-contamination.
For example, if a cutting board used for raw chicken is not cleaned before preparing a salad, bacteria could spread to the fresh ingredients, posing a risk of foodborne illness.
