Red Meat Allergies Caused by Lone Star Tick Bites Are Increasing Across the U.S.
Being bitten by a Lone Star tick can cause you to develop an allergy to red meat, even if it’s something you’ve eaten for your entire life.
Dr. Scott Commins, who was one of the first physicians to recognize the link between red meat allergies and Lone Star tick bites, went on to discuss the growing severity with NPR. He said there were just a few dozen known cases just 10 years ago, but today he said doctors are “confident the number is over 5,000 [cases], and that’s in the U.S. alone.”
He also added that while the ticks are most frequently found in the Southeast portion of the United States, “the range of the tick is expanding.”
According to the American College of Allergy Asthma & Immunology, “this specific allergy is related to a carbohydrate called alpha-gal and is best diagnosed with a blood test,” adding that it can often take hours after eating red meat products before “the appearance of an allergic reaction.”
The Center for Disease Control also recently announced that reported illnesses from mosquito, tick and flea bites have tripled across the United States, with nine new germs from mosquitoes and ticks being introduced into the country over the past 13 years.
“We do get them here occasionally in the state,” Griffin Dill, pest management specialist for the University of Maine Cooperative Extension, told the Bangor Daily News, before adding that authorities aren’t sure “whether they were bit by a lone star tick here in Maine or if it was travel-related.”
Dill went on to call the Lone Star ticks “more of an aggressive species,” saying that while “the deer and dog tick are relatively passive … lone star ticks will actually move in response to stimuli. If they sense carbon dioxide or movement, that sort of thing, they’ll actually travel in that direction.”
While the Lone Star tick — named for their distinctive “lone” dot marking — has not been found everywhere in the United States, in an interview with the Chicago Tribune, Ronald Saff, an allergist from Tallahassee, Florida, shared that “as the U.S. gets warmer, we anticipate that the tick will migrate to other states.”
