New Jersey Man Dies From Meat Allergy Triggered by Tick Bite

First Confirmed Death From Alpha-Gal Syndrome

A 47-year-old New Jersey pilot ate a hamburger at a backyard barbecue in September 2024. Four hours later, his son found him unconscious on the bathroom floor.

Doctors could not explain his death. The autopsy showed no heart attack, no stroke, nothing obvious.

His widow spent months searching for answers, and what she eventually learned has implications for anyone who spends time outdoors in tick country.

He Had a Warning Two Weeks Earlier

The man had gone camping with his family that summer. After a steak dinner around 10 p.m. , he woke up with severe stomach pain, diarrhea, and vomiting that lasted two hours.

He told his son he thought he was going to die. By morning he felt better, so he never saw a doctor.

He had no idea the steak was the problem, and no idea a tick bite weeks earlier had changed how his body processed red meat.

A Ballet Mom Connected the Dots

The victim’s widow kept asking questions after his death. She talked to Dr. Erin McFeely, a pediatrician whose daughter danced ballet with her daughter.

McFeely knew about alpha-gal syndrome and suggested the meat allergy might explain what happened.

She connected the widow with Dr. Thomas Platts-Mills at the University of Virginia, the allergist who discovered the condition in 2007.

Blood Tests Found What the Autopsy Missed

Dr. Platts-Mills analyzed a blood sample collected after the man’s death.

The results were staggering. Tryptase, a marker for severe allergic reactions, measured at 2,000 milligrams per milliliter.

The highest level Platts-Mills had ever seen in a survivor was 100.

The blood also contained antibodies to alpha-gal, confirming the man had died from anaphylaxis triggered by the hamburger.

Those Bites Were Not Chiggers

Earlier that summer, the man had noticed about a dozen small, itchy bites around his ankles. He assumed they were chigger bites.

Researchers now believe they were actually bites from lone star tick larvae, which are tiny and easily mistaken for other insects.

Those bites likely sensitized his immune system to alpha-gal, setting up the fatal reaction months later.

This Tick Rewires Your Immune System

The lone star tick carries alpha-gal, a sugar molecule found in most mammals but not in humans. When the tick bites, it transfers alpha-gal into your bloodstream.

Your immune system may then start producing antibodies against it.

The next time you eat beef, pork, or lamb, your body treats that meat as a threat and launches an allergic response.

Reactions Come Hours After Eating

Most food allergies hit within minutes. Alpha-gal is different.

Symptoms typically appear two to six hours after eating red meat, which makes the condition extremely hard to diagnose.

Many people wake up in the middle of the night with hives, stomach cramps, or breathing problems and never connect it to dinner. Some get misdiagnosed with irritable bowel syndrome or panic attacks for years.

Up to 450,000 Americans Are Affected

More than 110,000 suspected cases of alpha-gal syndrome were identified between 2010 and 2022. The actual number is not known, but as many as 450,000 people may be affected.

A 2022 CDC survey found that 42 percent of healthcare providers had never heard of the condition. Researchers reported a 100-fold increase in positive test results between 2013 and 2024.

These Ticks Keep Spreading North

Lone star ticks once lived mainly in southeastern states.

The northern range now extends to New Jersey, Rhode Island, New York, Connecticut, and possibly Maine.

Health experts advise hunters to be extra vigilant, with the lone star tick expanding into Michigan and other northern states. Warmer winters and growing deer populations are driving the expansion.

A New York tick lab reported that lone star tick encounters doubled from 2024 to 2025.

Exercise and Alcohol Raise the Risk

The New Jersey man had exercised and drunk a beer the day he died. Both factors can increase the absorption of food allergens and worsen reactions.

Researchers noted this in their report as a potential contributor to the severity of his anaphylaxis.

For people with alpha-gal syndrome, a hamburger after a workout or a steak with wine may be far more dangerous than the same meal eaten while resting.

No Cure Exists But Prevention Works

There is no vaccine or cure for alpha-gal syndrome. The only treatment is avoiding red meat and, for some people, dairy products.

The good news is that sensitivity can fade over time if you avoid additional tick bites.

The CDC recommends treating clothing and gear with products containing 0.5 percent permethrin, which kills ticks on contact. DEET applied to skin provides additional protection.

Know the Signs Before Its Too Late

The New Jersey man might be alive if he had known what those ankle bites really were, or if he had recognized his camping trip illness as an allergic reaction.

Symptoms of alpha-gal syndrome include hives, nausea, stomach pain, breathing issues, and swelling, usually appearing two to six hours after eating meat or dairy.

If you spend time outdoors in tick habitat and develop unexplained reactions after eating red meat, ask your doctor about alpha-gal testing. One blood test could save your life.
