Perishable foods are defined as foods that can become unsafe or spoil quickly if not refrigerated or frozen.

• A. Foods that can become unsafe or spoil quickly if not refrigerated or frozen.
• B. Foods that have long shelf life at room temperature.
• C. Foods that do not require refrigeration.
• D. Foods that can never spoil.

Answer: (A)

Perishable foods are those that can become unsafe or spoil quickly if not kept cold. The key idea is that these foods support rapid bacterial growth and spoilage when left at room temperature, so refrigeration or freezing is needed to slow or stop that process. This includes items like dairy, raw or cooked meats and fish, eggs, and prepared foods—anything that deteriorates quickly without chilling.

Refrigeration lowers the temperature to slow microbial growth and enzyme activity, helping prevent foodborne illness and preserve quality. The other statements describe foods that are stable at room temperature, or claim something that isn’t true about spoilage, which is why they don’t define perishable foods.
