When is it unnecessary to wash hands while preparing food?

It is unnecessary to wash hands when putting on gloves because the act of donning gloves is typically done to create a barrier between hands and food. However, it is essential that hands are clean before putting on gloves to ensure that no contaminants are transferred from the hands to the food. If hands have been properly washed prior to gloving, then there is no need to wash them again immediately before putting on gloves. This principle reinforces the idea that clean gloves can effectively prevent contamination, as long as the hands are already sanitized before the gloves are applied. Proper glove usage combined with clean hands significantly reduces the risk of foodborne illnesses.
