Pack Foods With Care When Traveling
Keep cold food cold.
Place cold food in coolers with frozen gel packs or ice. Stashing it at 40°F or below prevents bacterial growth. Consider packing beverages in one cooler and perishable foods in another since you are likely to grab beverages most often.
Keep hot food hot.
That means your best bet when packing is to take a pass on hot food unless you have a portable heating unit that can be used safely.
