New research has shown that the risk of developing a red meat allergy after being bitten by a tick may be much higher than scientists had thought.  The previous understanding was that a tick needs to have recently fed on the blood of a non-human mammal before it bites and causes the allergy in a human.  Researchers at the University of North Carolina have now found that some ticks can cause the allergy to develop, irrespective of what they have recently fed on.
