Final answer:
Cross-contamination, the transfer of bacteria or other pathogens from one source to another, is indeed true and can occur in settings such as food preparation.
Step-by-step explanation:
The statement that cross-contamination is the transfer of bacteria or other pathogens from one source or surface to another is true. Cross-contamination typically occurs when harmful microorganisms, like bacteria, are unintentionally transferred from one substance to another, potentially causing harm. This can happen in various scenarios, such as when raw foods containing bacteria, such as Salmonella (found in poultry, eggs, and meat), come into direct or indirect contact with ready-to-eat foods. To prevent this, it’s important to use separate utensils, cutting boards, and to properly clean all surfaces between the preparation of different foods. Additionally, exposure to pathogens can happen through vectors like insects or by touching contaminated surfaces where pathogens are present.
