Which method is NOT permissible for handling ready-to-eat foods?

Using bare hands to handle ready-to-eat foods is not permissible because it poses a significant risk of contaminating food with pathogens or allergens that may be present on a person's skin. This practice violates food safety regulations aimed at preventing foodborne illnesses.

In contrast, using tongs, gloved hands, or deli paper provides safe alternatives for handling these foods, as these methods help minimize direct contact with the food. Gloves can create a barrier that protects the food from contaminants, while tongs and deli paper allow for manipulation without touching the food directly, thereby promoting hygiene and safety in food service environments.
