Martha's Vineyard and Midwest ERs See Alpha-Gal Allergy Surge
More than 500 cases were confirmed last year as a growing lone star tick population forces dietary shifts and increases vegan options on the island.
- Martha's Vineyard saw 523 positive cases of alpha-gal syndrome out of 1,254 tests reported in 2025, affecting residents with a meat allergy.
- The rise followed warmer temperatures and expanding lone star tick populations that spread the sugar molecule alpha-gal causing allergic reactions.
- Residents and businesses responded by avoiding red meat and dairy, creating vegan menus, and selling plant-based substitutes amid growing community concern.
- A man in his late fifties who previously worked as a chef experienced anaphylactic shock in 2020 after consuming a steak meal, displaying severe allergic reactions such as widespread hives and difficulty breathing.
- The increase signals broader spread of alpha-gal syndrome across the U.S. linked to climate change, prompting calls for prevention and awareness in tick-infested areas.
