![]() ![]() Individuals with alpha-gal allergy do not need to become strict vegetarians because reptile meats, poultry and seafood naturally do not contain alpha-gal. Some afflicted individuals are so hypersensitive to alpha-gal that the allergy can cross-react with mammalian gelatin and even some dairy products. Healthcare providers recommend avoiding food products containing beef, pork, lamb, venison, rabbit and offal to avoid triggering an allergic reaction. The alpha-gal molecule is found in all mammals except catarrhines ( apes and Old World monkeys), the taxonomic branch that includes humans.īites from specific tick species, such as the lone star tick ( Amblyomma americanum) in the US, and the paralysis tick ( Ixodes holocyclus) in Australia, which can transfer this carbohydrate to a victim, have been implicated in the development of this delayed allergic response to consumption of mammalian meat products (“ red meat”). Anti-gal is a human natural antibody that interacts specifically with the mammalian carbohydrate structure gal alpha 1-3Gal beta 1-4GlcNAc-R (the alpha-galactosyl epitope). Īlpha-gal allergy is a reaction to the carbohydrate galactose-alpha-1,3-galactose ("alpha-gal"), whereby the body is overloaded with immunoglobulin E (IgE) antibodies on contact with the carbohydrate. Symptoms of the allergy include rash, hives, nausea or vomiting, difficulty breathing, drop in blood pressure, dizziness or faintness and severe stomach pain. The condition results from past exposure to certain tick bites. Abdominal pain, anaphylaxis, angiodema, headaches, congestion, diarrhea, faintness, hives, nausea, rhinorrhea often with sternutationīites from certain species of ticks predominantly the Lone Star tickĪlpha-gal syndrome (AGS) (also Alpha-gal allergy Mammalian meat allergy (MMA)) - is a type of meat allergy characterized by a delayed onset of symptoms (3–8 hours) after ingesting mammalian meat.
