When most people in New Jersey think of tick-borne illnesses, Lyme disease is usually the first thing that comes to mind. But there’s another hidden risk on the rise—the red meat allergy, or alpha-gal syndrome, caused by the bite of the lone star tick. At HMGS Dermatology, we care about keeping you and your family informed about emerging health risks affecting your skin and overall wellness.
What Is Red Meat Allergy (Alpha-gal Syndrome)?
Red meat allergy is a unique allergic reaction triggered by a sugar molecule called alpha-gal, which the lone star tick injects into your body during a bite. This syndrome is quite different from other food allergies—symptoms can appear up to 3-6 hours after eating red meat such as beef, pork, or lamb. In some cases, even products derived from mammals can spark a reaction.
- Tick-borne: Caused by the bite of the lone star tick—now increasingly common in New Jersey.
- Symptoms: Include itchy rashes, hives, swelling, stomach pain, and, in rare cases, severe allergic reactions known as anaphylaxis.
- Delayed onset: Unlike most food allergies, reactions occur hours after consumption, making it trickier to pinpoint the cause.
What Is STARI?
The lone star tick isn’t just responsible for alpha-gal syndrome—it can also cause a rash called STARI (Southern Tick-Associated Rash Illness). This rash is circular or expanding and looks similar to the hallmark “bull’s-eye” rash from Lyme disease. While STARI is usually milder than Lyme disease, it’s still important to seek medical attention if you notice a suspicious rash after a tick bite.
Other Tick-Borne Illnesses in New Jersey
Several types of ticks thrive in New Jersey, each carrying unique risks. Here’s a quick overview of the most common tick-borne illnesses:
- Lyme Disease: Blacklegged tick; look for target-shaped rash, fever, joint pain.
- Ehrlichiosis: Lone star tick; causes fever, muscle aches, sometimes a rash.
- Babesiosis: Blacklegged tick; may bring on fevers, chills, and fatigue.
- STARI: Lone star tick; produces a bull’s-eye rash, sometimes fatigue.
- Alpha-gal Syndrome: Lone star tick; results in rash, hives, or allergic reaction after eating red meat.
Why Dermatology Is Essential for Tick-Borne Illnesses
Skin changes—such as unusual rashes, hives, or swelling—are often the very first signs of tick-borne diseases like alpha-gal syndrome. A dermatologist can help differentiate between tick-borne allergic reactions and other skin problems. At HMGS Dermatology, our experienced team is skilled in diagnosing and treating skin conditions caused by tick exposures.
How to Protect Yourself and Your Family
- Wear insect repellent and long sleeves when spending time in grassy, bushy, or wooded areas.
- Do a thorough tick check of your skin after outdoor activities, especially for children and pets.
- Shower soon after being outdoors to help wash away unattached ticks.
- Contact a dermatologist promptly if you notice unusual rashes, hives, or swelling after spending time outside—or hours after eating red meat.
