A food worker makes sandwiches using tuna salad prepared yesterday. How should the food worker label the sandwiches with a use-by date?

Answer:- A sandwich prepared using tuna salad must be branded with a use-by date. Tuna salad sandwiches characteristically indulge after 7 days and must not be eaten to evade food poisoning. Some foods are branded as unpreserved foods. The perishable foods are distinct as the foods which gets spoiled within few days. Likewise, so there are some kinds of food which do not get ruined for many days. This happens since of the incidence of chemicals in the food. The chemical which is present is in control for the corrosion and reduction reaction.
