Anaphylaxis caused by inhaled pavlova mix in egg-sensitive children.

Two cases of anaphylactic reactions that occurred in young children with clinical hypersensitivity to egg protein after their exposure to a pavlova mix (which contains powdered egg-white) are described. The exposure took place when a packet of pavlova mix was opened and its contents were transferred into a bowl by adults. Although the children were in the same room, no direct contact was made. This indicates that the exposure occurred by way of the inhalational route. Clinical sensitivity to eggs is common in infancy and early childhood. Parents of children who have experienced immediate hypersensitivity reactions to egg-protein should be aware of the potential hazard of pavlova mixes and other sources of egg-white powder.
