Ticked off: How a bite

Tick bites linked to red meat allergy in new study

A tick bite can trigger a meat allergy that makes it hard or impossible to eat red meat without an allergic reaction. This condition, called mammalian meat allergy, is one of the few food allergies caused by something in the environment rather than the food itself. If you've noticed new reactions to beef or pork after a tick bite, this could be why.
