Outer Cape Health Services (OCHS) Urges Awareness of Alpha-gal Syndrome on Cape Cod

Tick-Acquired Red-Meat Allergy Calls for Early Recognition and Prevention

Harwich Port, Mass., June 29, 2026 –  Outer Cape Health Services (OCHS), a federally qualified community health center serving the outermost towns of Cape Cod, is encouraging residents to become familiar with Alpha-gal syndrome (AGS), a tick-associated allergy that Massachusetts public health officials have identified as an emerging condition in the state, including on Cape Cod.

The Massachusetts Department of Public Health began requiring healthcare providers and laboratories to report confirmed and suspected cases of Alpha-gal syndrome on April 1, 2026, to enhance surveillance and prevention efforts statewide. Regional news reports, citing state health officials, have reported 16 Cape Cod cases as of early June.

Unlike Lyme disease and many other tick-borne illnesses, Alpha-gal syndrome is not caused by a bacterial or viral infection. Instead, it is an allergic reaction associated with a bite from the Lone Star tick and is named for the alpha-gal sugar involved in the human immune response. People with AGS may experience delayed symptoms after eating red meat, including beef, pork, and sometimes dairy products. Poultry, fish and other seafood are not affected.

“One of the challenges with Alpha-gal syndrome is that people often don’t connect their symptoms to a tick bite because the allergic reaction usually doesn’t happen until hours after eating red meat, and it may occur weeks or even months after the bite itself,” said Gretchen Eckel, Population Health and Child Health Director at Outer Cape Health Services. “That’s why it’s important to tell your healthcare provider about any recent tick exposure if you’re experiencing these kinds of symptoms.”

Alpha-gal syndrome typically causes symptoms two to six hours after eating red meat. Symptoms may include hives, itching, rash, stomach pain, nausea, vomiting, diarrhea, dizziness and shortness of breath or, in severe cases, anaphylaxis, a life-threatening allergic reaction requiring immediate emergency medical care.

Lone Star ticks, the primary tick associated with Alpha-gal syndrome, are reddish-brown and identified by a single white spot on the backs of adult females. Males have lighter markings around the edge of the body. The Centers for Disease Control and Prevention notes Lone Star ticks are established in the Mid-Atlantic states and have been expanding into the Northeast. If possible, residents should save a removed tick in a sealed container or bag and bring it with them when seeking medical care, as identification can help guide evaluation.

OCHS encourages residents to reduce their risk of tick bites by using insect repellents containing DEET or picaridin as directed, wearing long sleeves and long pants when outdoors, staying on maintained trails, performing thorough tick checks after spending time outdoors, and showering soon after coming inside.

Anyone who develops delayed allergic symptoms after a tick bite or after eating red meat should seek medical care promptly. If Alpha-gal syndrome is suspected, avoiding trigger foods until evaluated by a healthcare provider may help prevent additional reactions. Please visit www.outercape.org or call (508) 905-2888
