Twenty-five patients living in a tick-endemic region of Sydney, New South Wales developed red meat allergy after experiencing large local reactions to tick bites. This represents a potentially novel cross-reaction between an arthropod and a food protein.

Between 2003 and 2007, 25 patients (seven men, 18 women; mean age [range], 29.9 [21–63] years) presented to our allergy practice in Sydney, New South Wales with a history of an allergic reaction to red meat.
