Key takeaways
An unusual route to food allergy
Alpha-gal is present in most non-primate mammals. A tick bite can sensitise some people, after which meat, dairy, medicines or other mammal-derived materials may trigger reactions of varying severity.
Specialist guidance matters
Symptoms and tolerances differ between people. Diagnosis and avoidance planning should be led by an allergist or other qualified clinician, with emergency instructions for severe reactions.
