Final answer:
Sharing utensils between dishes can cause cross-contact with one of the 8 major food allergens.
Step-by-step explanation:
The practice that could cause cross-contact with one of the 8 major food allergens is D) Sharing utensils between dishes.
Cross-contamination occurs when microbes are transferred from one food to another. If utensils that have touched an allergen are then used to prepare another dish without proper cleaning, it can lead to the transfer of allergens and potentially cause an allergic reaction in individuals with food allergies.
For example, if a knife is used to cut a peanut butter sandwich and then used to cut a piece of bread for a person with a peanut allergy, the peanut allergens can be transferred to the bread, posing a risk to the person with the allergy.
