Conclusions

The major risk factors for red meat allergy after tick bites include male sex, non-B blood type, systemic mastocytosis, a bovine or porcine bioprosthetic heart valve, and preexisting allergies to gelatin or animal dander. Following confirmation by challenge testing, patients with red meat allergies should avoid red meat, foods containing gelatin, and intravenous immunotherapy with monoclonal antibodies produced in SP2/0 mouse cell lines, such as cetuximab and infliximab. Red meat allergy after tick bites represents an emerging threat from tick bites in addition to infectious diseases.
