Lone star tick causes alpha-gal meat sensitivity in regional population

"These findings suggest that other species of ticks, or possibly human factors, may play a role in allergic reactions to alpha-gal," said Dr. Fineman. "Patients with delayed allergic reactions after eating meats should see an allergist to determine if it is an alpha-gal allergy. The best treatment is strict avoidance of meat. An allergist may also prescribe epinephrine in the event of a life threatening emergency."

Unlike other food allergies, alpha-gal meat allergy can be delayed as long as three to six hours after eating meat. Symptoms range from mild to severe and may include:

• Hives or skin rash
• Nausea, stomach cramps, indigestion, vomiting, diarrhea
• Stuffy/runny nose
• Sneezing
• Headaches
• Asthma
• A severe allergic reaction is known as anaphylaxis, which starts rapidly and may cause death

If you experience an allergic reaction after eating meat, seek emergency medical attention. Follow up with a board-certified allergist who can develop a treatment plan for you and prescribe life-saving epinephrine.
