Meat Allergy Caused By Tick Bite

Lone Star Tick causing meat allergies in central Virginia

By Kris Van Cleave June 18, 2012 - 03:49 pm

...

The allergy concerns people throughout the Commonwealth who have been bitten by the Lone Star Tick. People who are affected have found themselves totally unable to consume red meat.

...

Just posting a snippet but full story is at the link. Seems strange that people get a meat allergy after being bitten by a tick? I hadn't heard of that one before.

Now that IS interesting. Also, did you notice this?

"My life would be over if I couldn't eat red meat," Alexandria resident David Kudlow said. "If I couldn't have steak, I probably wouldn't want to live much longer."

Another one who doesn't THINK before he speaks!

I have heard of a few times and those I have been in contact with it say that they are unable to eat anything on hooves, not just red meat. I would find that very difficult myself. It is strange, though. I would like to learn more about it.

Well, at least I know which parts of the world I should avoid: http://www.cdc.gov/ticks/maps/lone_star_tick.pdf

I know I could live without eating meat, but I definitively don't want to.

Maybe it has something to do with antibodies cross-reactivity? Body will make antibodies against some infection transfered buy the bug and these will cross-react with certain meat proteins? There are theories linking autoimmune diseases to infections via the same route.

This is scary. Very scary. Glad there is medical research being done on this. The article and video is interesting but doesn't explain any possible mechanisms causing the "allergies." Likely just too soon into the research. I wonder if a similar epitope is shared between meat protein and some sort of bacteria or immunogen (possibly from bacteria) that the tick could be carrying, causing an overreaction of the immune system? The delayed reaction of 2-4 hours could also mean the small bowel could be involved somehow because this is about the time it would take for the food to reach the duodenum. Overall very interesting and frightening but need more details in order to speculate further. I know there is a similar thing with ciguatera fish poisoning and nuts, but it is not well researched.

Edit: There's an article on CNN about this giving more information.

http://www.cnn.com/2012/06/20/health/meat-tick-bite-allergy/index.html?hpt=he_c1

According to the article it is apparently a true allergic reaction to not a protein but a sugar, galactose-alpha-1,3-galactose which is found in all mammallian meat barring humans, apes and greater primates. And the reaction is delayed. This would be considered highly unusual but is very, very interesting. I wonder if there could be more of these types of delayed allergic reactions going on that are unidentified and not necessarily related to meat or ticks.

I recently found myself getting digestive problems after eating venison, then I noticed it after eating beef. I found the tick articles and put it together. I'm in central Texas on 4 acres and must have picked up a tick without realizing it. There are specific sugars in red meat and pork that cause an allergy in some people bitten by the common lone star tick. Amazing!
