The tick outbreak threatening to ruin American’s summer

Key Points:

• Martha’s Vineyard, once famous for the movie Jaws, is now facing a new threat from invasive lone star ticks that cause alpha-gal syndrome, an allergy to red meat and other animal products triggered by tick bites.
• Cases of alpha-gal syndrome on the island have surged dramatically, with confirmed cases rising from 2 in 2020 to 724 in 2025, prompting Massachusetts to begin statewide tracking of the condition.
• Alpha-gal syndrome symptoms can be severe, including vomiting, hives, and potentially life-threatening anaphylactic shock, and the allergy is now the 10th most common food allergy in the US, affecting an estimated 450,000 Americans.
• The spread of lone star ticks is influencing local lifestyles and businesses, with residents adopting protective measures and some restaurants offering “alpha-gal-safe” menu options to accommodate those affected.
• Massachusetts health officials warn that lone star ticks are spreading across the state, and experts expect the problem to expand further, highlighting the need for increased public health attention and legislative action.
