Tick Linked to Meat Allergy Expands Its Range
The lone star tick, a vector for meat and dairy allergies, is moving northward, prompting warnings from health officials. Originally found in the southern United States, it is now confirmed in over two dozen states, including recent sightings in Michigan.
Lone star tick: Characteristics and identification
The lone star tick, known for its rapid movement and aggressive biting, is easily identifiable. Adult females feature a single white dot on their backs, while males have black streaks. Experts noted their resurgence in the Northeast and Great Lakes regions, attributed to milder winters, invasive plants, and rising deer populations.
Alpha-gal syndrome: A serious allergy—Symptoms
This tick is associated with alpha-gal syndrome (AGS), a potentially life-threatening allergy to red meat and mammalian products. Symptoms mimic those of typical allergic reactions, including hives, breathing difficulties, and digestive issues. The CDC reported over 110,000 suspected AGS cases from 2010 to 2022, with actual numbers likely higher due to underreporting.
With summer’s arrival, ticks, including the lone star tick, are thriving. Reports of increased tick activity have raised concerns among health officials. In Kansas, a rise in tick-associated conditions like AGS has been noted.
Prevention and safety tips
To reduce the risk of tick bites, experts recommend using repellents containing at least 20% DEET, wearing long sleeves and pants, and avoiding areas with tall grass and leaf litter. After outdoor activities, showering and conducting thorough body checks for ticks are crucial.
Dr. Seth Mobley, a family medicine doctor, explains that AGS symptoms can range from mild to severe but typically don’t require emergency treatment like an EpiPen. Hayden Hurtig, diagnosed with AGS in middle school, avoided red meat for years and eventually overcame the allergy. “Cutting it out completely speeds up recovery,” Hurtig advised.
Health officials continue to monitor the lone star tick’s spread and its public health impact. The CDC advises those with AGS to avoid mammalian meat and milk products, though some may outgrow the allergy over time.
