Please do not buy sandwiches prepared by grocery stores, as their temperature is not ideal, and I see them throwing them in the trash can once in a while.
Food at Chick-fil-A, McDonald’s, Whataburger, etc., might not be healthy, but they do not have a temperature problem.
Grocery stores must sell fresh sandwiches so they do not need to throw them away.
Store sandwiches at or below 40°F (4°C) in a refrigerator to prevent the growth of harmful bacteria.
The range between 40°F and 140°F is known as the “Danger Zone” for temperature. Within this range, foodborne bacteria can multiply rapidly and cause illness.
