What should food workers use to touch food from display cases

They should wear gloves and utensils that are clean and sanitized.

Explanation:

In general, the glove protects food from possible contamination by contacting handlers' hands with food without strict hygienic care. However, the use of disposable gloves, contrary to what many people think, should not be present in all food handling processes.

Gloves if not used properly can become a source of food contamination. These gloves are suitable for food handling, but better than using gloves is to wash your hands well and use clean and sanitized utensils.

it is definitely false.
