Which of the following is NOT associated with cross-contact?

The concept of cross-contact refers to the unintentional transfer of allergens from one food to another, which can occur in food preparation and serving environments. The answer about separate cooking surfaces is identified as NOT associated with cross-contact because using separate cooking surfaces is a common practice that helps to prevent cross-contact. When different cooking surfaces are used for different foods, particularly for allergenic versus non-allergenic foods, the risk of allergens transferring is significantly reduced.

In contrast, using the same utensils, shared cooking vessels, and contact during serving can easily lead to cross-contact. For example, if a utensil that has touched allergenic food is then used on non-allergenic food without being cleaned, this can cause cross-contact. Similarly, cooking vessels that have been used for both allergenic and non-allergenic foods can also lead to the transfer of allergens. Contact during serving poses similar risks, as food can be inadvertently mixed or contaminated if proper precautions aren't taken.

Thus, the use of separate cooking surfaces is a proactive measure designed specifically to prevent cross-contact, making it the correct answer in this context.
