New Tick Species Found to Cause Life-Threatening Red Meat Allergy

Alpha-Gal Syndrome: New Tick Species Identified in the U.S. A recent case of a severe allergic reaction in Washington state has highlighted the growing threat of alpha-gal syndrome. Cathy Raley, a 61-year-old woman, experienced a life-threatening reaction after being bitten by a tick. This prompted an investigation by the CDC, which uncovered two new tick species that can trigger the allergy. "I was hiking with my dog when it happened," Raley recalls. "I started getting hives and my throat closed up." The CDC's investigation revealed that Raley's allergy stemmed from a western black-legged tick bite. Another similar case from Maine was linked to a deer tick. Scientists emphasize the importance of avoiding tick bites, especially in wooded areas, and recommend wearing tightly woven insect-repellent treated clothing. Raley, who has avoided red meat for eight years since the incident, is now doing well. This case underscores the need for public awareness of alpha-gal syndrome and the expanding range of ticks that can cause it.
