Alpha-gal/Meat Allergy

Alpha-Gal

Meat allergy caused by the bite of the lone star tick, Amblyomma americanum.  

The tick’s saliva triggers immune response to a carbohydrate, alpha-gal, found in red meat. Although eating red meat is the most common allergic trigger to alpha-gal, ingredients found in everyday products such as dairy, gelatin, soap, cosmetics, lotions, household products, and medications can also cause an allergic reaction.*

Symptoms: Can develop 3-4 hours after exposure and include upset stomach, headaches, hives, rashes, swelling, shortness of breath, anaphylaxis.
