If you are allergic to meat, your body considers meat to be a physical threat. The first time you have this response, your immune system makes specific immunoglobulin e (ige) antibodies to fight the threat off. These antibodies attached to immune cells throughout your body.
After that, each time you eat meat, the allergen binds to the ige antibodies and causes the cells to release massive amounts of histamine and other chemicals to try to protect you.
Depending on the tissue in which these antibodies are released, these chemicals will cause you to have symptoms that can range from mild to severe. A severe allergic reaction can include anaphylaxis, a potentially life-threatening reaction that must be treated immediately.
A bite from the lone star tick can cause people to develop an allergy to red meat, including beef and pork. This specific allergy is related to a carbohydrate called alpha-gal and is best diagnosed with a blood test. Although reactions to foods typically occur immediately, in the instance of allergic reactions to alpha-gal, symptoms often take several hours to develop. Owing to the significant delay between eating red meat and the appearance of an allergic reaction, it can be a challenge to connect the culprit foods to symptoms.
