Which actions could cost cross contamination in self service area?

Cross-contamination in a self-service area can occur when customers use the same utensils for different food items, such as scooping from a salad bar and then using the same tongs for a meat dish. Inadequate handwashing or the absence of hand sanitizer stations can also contribute, as patrons may not properly clean their hands between handling different food types. Additionally, improper food placement, where raw items are near ready-to-eat foods, increases the risk of contamination. Regular monitoring and clear signage can help mitigate these risks.
