‘My worst nightmare’: Meat-eaters terrified as tick that can make you permanently allergic to red meat ‘is spreading’

Enjoy a juicy steak? Well, savor it while you can, because it could be your last if the Lone Star tick has anything to say about it. As incredible as it sounds, a single bite from this tick could give you a permanent and inescapable aversion to mammalian “red” meat, meaning beef, pork, lamb, venison, and rabbit are permanently off the menu. In some cases, sufferers also cannot tolerate dairy.

This isn’t necessarily enforced vegetarianism, as those who pick up this condition can still eat poultry, reptile, and seafood meats, but it certainly limits what your body will tolerate – and will mean you’ll have to cancel any plans to visit a steakhouse.

One post (anecdotally) reports on the effect this tick bite had on her cousin:

My cousin got bit by one of these and now she can’t even be in the same room and or basically house as family when they’re having or cooking red meat for dinner https://t.co/dRNkz0VTYB

“My cousin got bit by one of these and now she can’t even be in the same room and or basically house as family when they’re having or cooking red meat for dinner.”

Worryingly, its territory is spreading fast. It’s firmly established in the southeastern and eastern United States and is found in Texas, Oklahoma, and Missouri in wooded and bushy areas. But a changing climate has proved favorable to its spread, and scientists have detected “established populations” in Illinois and Iowa, as well as on Martha’s Vineyard.

What does it do to you?

The Science behind it.
Once you have circulating memory B-cells of an antibody, you'll never get rid of it.
Literally like vaccines, but instead of attacking harmful pathogens, it's just a common protein.
Any time it replicates, it makes more memory cells and antibody cells. pic.twitter.com/nOmi6KeWd8

The red meat allergy results from its bite causing alpha-gal syndrome, meaning your body reacts violently to the presence of the alpha-gal carbohydrate molecule found in all mammals. This causes hives, diarrhea, full-body itching, sweating, and even full anaphylaxis 3-8 hours after eating red meat.

There is no cure, with those affected forced to simply stop eating red meat. You may recover from it in time, or you may not and be permanently barred from hamburgers forever. If there’s a silver lining, not every Lone Star tick bite will give you the allergy.

Even so, this is far from a rare condition. Cases are growing, with the CDC classifying it as an “emerging threat” and documenting around 15,000 new cases of red meat allergy per year.

If not being able to enjoy a juicy steak ever again sounds like hell, then if you’re in rural areas avoid tall grass or bushy areas, wear long sleeves and pants, use bug spray, and after being outside, do a full body scan for ticks. It might sound drastic, but if it’s between and never being able to order a quarter-pounder again…
