Lone Star Ticks Surge in Wisconsin
23 Jul
Summary
- Lone star ticks, linked to red meat allergy, show a sharp increase in Wisconsin.
- Alpha-gal syndrome diagnoses are rising, potentially linked to various tick species.
- Tick bite victims face life-altering dietary changes and anxiety.
Wisconsin is experiencing a notable increase in lone star ticks, a species strongly associated with transmitting alpha-gal syndrome, an allergy to red meat. Submissions to the state's tick identification service show a jump from six in 2025 to 33 in the current year, indicating a growing presence. While increased public participation might contribute, health officials believe lone star ticks are having a greater impact.
Alpha-gal syndrome diagnoses are being made across Wisconsin, though not mandated for reporting. This condition can be life-altering, forcing individuals like Jordan Frangquist of Abrams to eliminate all animal meat from his diet after a 2024 tick bite. The allergy, identified less than 20 years ago, is estimated to affect up to 450,000 Americans. It occurs when the immune system reacts to the alpha-gal molecule transmitted through a tick bite.
Researchers are exploring the possibility that other tick species, including deer ticks, may also transmit alpha-gal syndrome, as the allergy exists in regions without lone star ticks. Prevention methods recommended by the state health department include wearing protective clothing, using repellents, treating clothes with permethrin, and conducting thorough body checks after outdoor activities.
