Are latex proteins from natural rubber latex gloves transferred to food?

Yes, latex proteins are transferred to almost any surface that is contacted by natural rubber latex gloves (1,2). This transfer is dependent on the concentration of NRL protein contaminating the glove and the texture of the surface that is contacted. The presence of moisture on the contact surface will enhance the transfer. We know that latex allergic patients can have severe allergic reactions to foods handled by latex gloves (2,3) where food cross-reactivity is not an issue. Low protein gloves transfer proteins at a level that we can not detect in the laboratory, however some highly sensitive patients may still be able to detect them. Based on our understanding of the available data, it is highly recommended that food handlers do not wear latex gloves.
