Alpha-gal syndrome isn’t going away.
In fact it is multiplying. As tick season reaches its fever pitch the allergy it triggers gets worse too. This isn’t just an itch. It can be fatal. One person is confirmed dead from the condition. Thousands are allergic to red meat because of it. And scientists are still guessing.
That uncertainty ended this past weekend. At least temporarily. Researchers gathered for the first dedicated conference on the disease in two days on July 7 and 8 Scott Commins of UNC School of Medicine led the charge. He helped discover the syndrome. Now he wants priorities. Funding. Answers.
“We need a national set of priorities,” he said.
It used to be considered rare. Look at TikTok now. Search Facebook. The “AlphaGal Kitchen” group just gained 4,000 new members in two weeks. It now has 82,00 strong. Why the sudden attention? Cases are spiking. A CDC study from 2010 to 2022 showed suspected cases rising every single year. They estimate 450,00 people have it. Probably an undercount. A new study from July found nearly a quarter of people in five southern states carry the antibody. Not all got sick. But they carry it.
Here is how it works. A lone star tick bites you. It injects a molecule called alpha-gal. Humans don’t make this stuff. Most mammals do. Your body freaks out. It builds an antibody. Then you eat a burger. Or drink milk. Or eat gelatin. The antibody attacks.
Sometimes nothing happens for hours.
This is the problem. You eat steak at dinner. You sleep fine. Then you wake up vomiting or wheezing or covered in hives. Did you eat bad meat? Or do you have irritable bowel? It is a guessing game. Some people can eat beef no problem. Others can’t touch gelatin. Some react to pig heart valves. Others explode if given heparin. It is chaotic. Unpredictable. Hard to pin down.
Is this an epidemic of anxiety or ecology? Both. Holly Gaff from Old Dominion University argues we built the perfect storm for this bug. We saved the white-tailed deer from extinction. Great news for nature. Bad news for our skin. More deer means more ticks. Ticks carry the molecule.
We brought the deer back into our backyards. Then we complained when they brought along the parasites. The range of these ticks is spreading too. West. North. Climate change helps. The deer spread so do the bites.
Sharon Forsyth of the Alpha-gal Alliance takes the calls when the doctors stop listening. She gets texts mid-conference from people with surgery tomorrow. Heparin contains pig lung derivatives. The doctor hasn’t checked the label. She isn’t a physician. But she has papers. She sends them. Hope the surgeon reads them.
She wants policy change. Mandatory labeling. Most drug companies won’t tell you if their product contains mammalian tissue. They hide in the fine print. She wants alpha-gal recognized as a major allergen like peanuts or shellfish. It fits. Just barely.
Nobody knows why some people get nothing and others nearly die. We don’t know what in the saliva causes the variation. Commins hopes new human trials might help. Maybe even a vaccine. Gaff appreciated the room. Entomologists talking to veterinarians. Epidemiologists talking to doctors. Usually those worlds don’t mix.
“It’s brilliant,” Gaff said. “We have our own silos. This broke them.”
For now you avoid beef. You check your medicine bottles. You trust your intuition. Or someone else’s Facebook group.
The deer are still out there. So are the ticks. And the science is still catching up to the bites.
