Pennsylvania Tracks Red Meat Allergy Cases Linked to Tick Bites
Pennsylvania Tracks Red Meat Allergy Cases Linked to Tick Bites
US · Published May 18, 2026
Pennsylvania health officials have initiated efforts to track alpha-gal syndrome (AGS), a red meat allergy caused by bites from lone star ticks.
The state, which leads the nation in reported Lyme disease cases, has identified approximately 600 AGS cases over the past two years through voluntary reporting.
The syndrome, which can cause severe allergic reactions to red meat, is linked to a sugar molecule transmitted by tick bites.

Why It's Important?

Alpha-gal syndrome poses a significant health risk, particularly in Pennsylvania, where tick activity is high year-round. The condition can lead to life-threatening allergic reactions to red meat, with the first documented fatality reported in New Jersey in 2024. While AGS is not yet a reportable disease in Pennsylvania, the state is taking proactive measures to monitor its spread. Vulnerable populations, including outdoor enthusiasts and residents in wooded areas, are at higher risk. The presence of lone star ticks and other tick species capable of causing AGS underscores the need for increased awareness and prevention efforts.
