Red meat allergy is a condition where individuals experience allergic reactions after consuming red meat, such as beef, lamb, or pork. This allergy is often linked to a specific carbohydrate called alpha-gal, which is found in the meat of mammals. The allergy can develop after a tick bite, particularly from the Lone Star tick, which can sensitize the immune system to this carbohydrate. Symptoms of red meat allergy can include hives, gastrointestinal issues, and even anaphylaxis in severe cases. Diagnosis typically involves a medical history review and allergy testing. Avoiding red meat and related products is the primary way to manage this allergy effectively.
