Tick-Borne Allergy Concerns Grow in the U.S.

As summer spreads across the Midwest, many Americans are grappling with tick bites. This season, there’s heightened awareness about lesser-known tick-borne diseases that are drawing attention from specific communities.

One significant concern is alpha-gal syndrome, linked to the lone star tick. This condition can trigger a severe allergy to meat and dairy, sometimes enduring for years. Those affected often find themselves needing to adopt a mostly vegan diet, and some experience intense reactions—merely smelling cooked meat can provoke a life-threatening response.

Lone star ticks, recognizable by the white spots on their backs, primarily inhabit wooded and grassy areas stretching from Maine down to Florida and Texas.

These ticks carry sugar molecules known as alphagals. When these are transmitted to humans, they may lead to significant allergic reactions to mammalian products.

According to the Centers for Disease Control and Prevention (CDC), around 450,000 individuals in the U.S. might have this syndrome.

Those affected report severe reactions—just being near a grilled burger can result in losing consciousness. This syndrome also impacts everyday items with animal byproducts, such as lip balms and certain lotions, leading to hives, coughing, and wheezing.

At Martha’s Vineyard, where cases have surged, restaurants now offer a specialized menu catering to those with alpha-gal syndrome.

Nicole Cooper, a Virginia resident diagnosed with the syndrome in December 2021, faced symptoms for over a year prior to receiving a correct diagnosis. She vividly recalls a moment where she struggled to breathe in an emergency room, with doctors noting a rash on her arm.

“I was taken aback when they suggested a blood test,” Cooper shared. “I really couldn’t stand those ticks; I mean, no way,” she added. “I always make sure to wear bug repellent when I’m out in the woods.”

As her condition worsened, she became “fume reactive,” which meant she had to avoid cooking meat or using any kitchenware that had previously touched it. Even lanolin from sheep, often found in certain products, became off-limits for her.

Alpha-gal syndrome complicates diagnosis and treatment, as there can be significant delays between exposure to ticks and the appearance of symptoms.

After two years of sensitivity, Cooper started experiencing improvement by strictly avoiding mammalian products.
