Summary
Food allergies, especially delayed hypersensitivity reactions, are often challenging for both patients and clinicians. Here, we report the case of a 64-year-old man who had allergic reactions six hours after eating a meal containing red meat. He reported that he had several tick bites in months before the reaction. High serum specific IgE levels of alpha-gal confirmed the diagnosis of alpha-gal allergic reaction with delayed onset after red meat ingestion caused by tick bite.
