Scientists began to notice the strange phenomenon a few years ago when taking a bite of a burger began to land people who had never had food allergies before in the hospital. As the so-called Lone Star ticks have spread from the Southwest to the East Coast, more people are getting bit and then going into anaphylactic shock when they try to eat red meat. Both doctors and patients are slow to recognize the risk. “Why would someone think they’re allergic to meat when they’ve been eating it their whole life?” Dr. Erin McGintee, an allergist who has reportedly seen 200 cases in New York’s Long Island, [told CBS News.](http://www.cbsnews.com/news/a-tick-bite-can-make-you-allergic-to-red-meat/) The bugs carry a sugar found in red meat called alpha-gal, which humans do not have. When humans eat this sugar in the form of beef, pork, venison or rabbit, they feel fine. But if the sugar is transferred into their bloodstream through a bite, the body creates antibodies to combat the foreign substance. So the next time the person encounters that sugar (by eating red meat), it sets off a potentially deadly allergic reaction that can include hives, itching, burning, and even the throat swelling shut. The symptoms can be treated with antihistamines in mild cases but must be treated with a shot of epinephrine in severe ones. Some people with the allergy have begun carrying EpiPens (shots of epinephrine) with them in case of another attack. (Some poultry products can contain meat byproduct and trigger the allergic reaction.) Unlike most common allergic reactions to foods like peanuts or shellfish, these allergic reactions can occur up to eight hours after the meat is consumed. The reason is most food allergies are caused by proteins, whereas this one is caused by a carbohydrate. Doctors don’t yet know whether the allergy is permanent. Some people show signs of recovery, and some don’t. Most people with the allergy are understandably hesitant to try red meat again. \[[_CBS News_](http://www.cbsnews.com/news/a-tick-bite-can-make-you-allergic-to-red-meat/)\] ```json [{"@context":"https://schema.org","@type":"NewsArticle","@id":"https://time.com/3090269/a-bite-from-this-tick-could-make-you-severely-allergic-to-red-meat/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3090269/a-bite-from-this-tick-could-make-you-severely-allergic-to-red-meat/"},"headline":"A Bite From This Tick Could Make You Severely Allergic to Red Meat","datePublished":"2014-08-08T01:38:24.000Z","dateModified":"2026-02-21T09:33:47.369Z","description":"Doctors suddenly see hundreds of cases","url":"https://time.com/3090269/a-bite-from-this-tick-could-make-you-severely-allergic-to-red-meat/","keywords":["Infectious Disease"],"thumbnailUrl":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0bb4ac941dba9142/69869ecf06f2c150a33303e3/lone-star-tick-red-meat-beef.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","author":[{"@type":"Person","name":"Eliana Dockterman","jobTitle":"Correspondent","url":"https://time.com/author/eliana-dockterman/"}],"articleSection":"Health","image":[{"@type":"ImageObject","url":"https://static.time.com/v3/assets/bltea6093859af6183b/blt0bb4ac941dba9142/69869ecf06f2c150a33303e3/lone-star-tick-red-meat-beef.jpg?branch=production&width=1200&quality=75&auto=webp&crop=1200:675&height=675","width":1200,"height":675,"headline":"Tick Meat Allergy","caption":"Tick Meat Allergy","creditText":"James Gathany—AP","representativeOfPage":true}],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/health/","name":"Health"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/infectious-disease/","name":"Infectious Disease"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3090269/a-bite-from-this-tick-could-make-you-severely-allergic-to-red-meat/","name":"A Bite From This Tick Could Make You Severely Allergic to Red Meat"}}]}] ```
