Perishable goods are items that have a limited shelf life and can spoil or degrade quickly, such as food products and certain pharmaceuticals. In contrast, durable goods are items designed for long-term use, typically lasting three years or more, like appliances, vehicles, and furniture. The key difference lies in their longevity and the frequency of consumer repurchase; perishable goods need to be replaced more often due to their short lifespan.
Basically, things that do not go "off" or grow mold or need to be kept in the refrigerator.
Most foods that are perishable need to be stored in a refrigerator. Perishable foods spoil faster if they are not refrigerated.
