What is purpose of storing food in a cooler?

Storing food in a cooler provides the necessary insulation and cool, low temperatures required for maintaining the safety and quality of perishable foods and beverages. When room temperature foods stay at unsafe temperatures for too long, the risk of bacteria growth that causes foodborne illnesses significantly increases. Coolers play a crucial role in preserving the safe temperatures of items like meats, dairy products, fresh produce, and prepared foods by preventing potential harmful temperature deviations over an extended period. Using adequate coolants like ice or freezer packs allows these items to be properly and conveniently transported as well as temporarily stored to prolong their edible shelf life.
