Verified step by step guidance

Understand the concept of a food allergy: A food allergy is an immune system reaction that occurs soon after eating a certain food. Even a tiny amount of the allergy-causing food can trigger signs and symptoms such as digestive problems, hives, or swollen airways.

Identify common symptoms of food allergies: Symptoms can include hives, swelling of the lips, tongue, or throat, difficulty breathing, and anaphylaxis, which is a severe, potentially life-threatening allergic reaction.

Recognize that fever is not typically associated with food allergies: Fever is generally a sign of infection or inflammation, not a direct symptom of an allergic reaction.

Compare the symptoms listed in the problem: Anaphylaxis, swelling of the lips, and hives are all common symptoms of food allergies, whereas fever is not.

Conclude that fever is the correct answer as it is not a possible symptom of a food allergy, based on the understanding of typical allergic reactions.
