A Common Tick Bite Can Make You Allergic To Red Meat. Here’s Who’s at Risk
Summary
A single bite from the lone star tick can cause a lifelong allergy to red meat known as alpha-gal syndrome. New federal research shows this allergy is more common than before thought, especially in five U.S. states where many people have antibodies linked to the condition.Key Facts
- Alpha-gal syndrome is an allergy triggered by a sugar molecule called alpha-gal found in beef, pork, and lamb.
- The lone star tick bite can cause the immune system to react to alpha-gal, leading to delayed allergic reactions several hours after eating meat.
- Symptoms can include stomach problems like pain, nausea, vomiting, and diarrhea, and in severe cases, life-threatening allergic reactions.
- The allergy may worsen with repeated tick bites, so avoiding ticks is important for people with the condition.
- A study tested blood samples from 10 states and found high rates of alpha-gal antibodies, especially in Arkansas (31%) and Missouri (26%).
- About 24% of people in Arkansas, Kentucky, Missouri, Tennessee, and Virginia tested positive for alpha-gal antibodies.
- Having antibodies does not always mean someone will show allergy symptoms, so diagnosis requires careful medical evaluation.
- People with alpha-gal syndrome should avoid mammalian meat but can eat poultry, fish, and shellfish; some may tolerate small amounts of dairy.
- Hidden animal products like beef broth, lard, and pork casings can trigger reactions, so reading food labels is necessary.
- Doctors recommend patients carry an epinephrine auto-injector to treat severe allergic reactions.
