According to the Daily Mail (and if you can't trust them, whom can you trust?) some tick bites can cause the victim to become allergic to red meat. Strewth.
There's a particular irony here:
Experts traced the delayed allergic response to bites from a tick - specifically the Lone Star tick.The Lone Star tick, presumably from the Lone Star State - Texas - famed for steaks the size of your dinnerplate. I have a horrible thought - is this the result of some fiendish genetic manipulation by the cows on whom the ticks normally prey? Mark Wadsworth, please call your office.
