Robbie Goldstein, commissioner of the Massachusetts Department of Public Health, announced at a Falmouth event hosted by Governor Maura Healey that the department will make alpha-gal syndrome a reportable condition beginning April 1 for at least the next year to improve surveillance, clinician recognition and public awareness.
Alpha-gal syndrome is an allergy triggered by the bite of certain ticks — most notably the lone star tick — that can cause delayed allergic reactions to mammal-derived foods and products such as beef, pork, lamb and dairy. Goldstein described the condition as difficult to diagnose because symptoms can appear hours after eating and often present as hives, gastrointestinal upset, fatigue or, in some cases, life-threatening reactions.
"Beginning April 1, the department of public health will make alpha gal syndrome a reportable condition for at least the next year," Goldstein said. He said requiring reports from clinicians and testing labs will improve the Department of Public Health’s data collection, support clinicians in recognizing cases, and enable more effective public-health education and prevention strategies.
Goldstein and other officials tied the shift in tick species and disease risk to climate change and said the lone star tick is now being seen on Cape Cod, Martha’s Vineyard, Nantucket and the mainland. He emphasized that alpha-gal is not an infectious disease in the usual sense but an allergy, and that prevention — avoiding tick bites through protective clothing, repellents and tick checks — is currently the only defense because there is no treatment to reverse the condition.
The DPH action is administrative surveillance: officials said it will allow better tracking and enable outreach to clinicians and residents. The event did not include details on reporting mechanisms, data release schedules, or the year-by-year criteria that would govern whether reportability is extended beyond the announced period.
