International Study of Risk-Mitigating Factors and In-Flight Allergic Reactions to Peanut and Tree Nut

In-flight peanut and tree nut reactions occur internationally. Epinephrine was sparsely used to treat reactions. We identified 8 risk-mitigating behaviors associated with lower odds of a reported reaction. Future study is necessary to further validate the effectiveness of these passenger-initiated risk-mitigating behaviors.
