Well, this is horrifying.
That, my friends, is a
Lone Star tick. Though already recognized as a potential carrier of four diseases which can be transmitted to humans, these suckers have another nasty trick up their sleeves. Some people who have been bitten have
developed extreme allergies to red meat, resulting in anaphylactic shock severe enough to require hospitalization. The other bad news? These little guys are spreading outside their traditional habitats (Southeast U.S.).
The allergy itself seems to be a result of the tick’s bite changing how the human immune systems responds to a sugar called galactose-α-1,3-galactose, or “alpha-gal” for short. Found in many non-primate mammals, alpha-gal is also found in cat dander, gelatin, and some drugs used to treat head and neck cancer. Sufferers have had to completely eliminate red meat from their diet, though poultry and seafood do not cause reactions.
