more accurate probably to wonder what they added to the ticks this time:

"How a tick bite can make you allergic to RED MEAT: Soaring numbers of people suffering violent reactions just hours after eating burgers and steak

• Doctors across the U.S. are seeing a surge of sudden meat allergies
• It's thought that bites of the Lone Star ticks are to blame
• People can go into anaphylaxis and break out in hives within hours of dining
• Some reactions are similar to those of a peanut allergy sufferer
• Sufferers may need to cut out red meat and milk - and carry an EpiPen
• Similar tick reactions also seen in Australia, France, Germany and Spain"
