Allergie bij het vissen

Two 37- and 39-year-old men without any relevant medical history developed allergic rhinoconjunctivitis while fishing. In the differential diagnosis allergy to pollen or fish feed ingredients, or fish or maggot contact allergy were considered. Further investigation of the case histories found that both men had been in direct contact with maggots of the Calliphora vomitoria fly. The allergic reaction attributed to the maggot exposure was confirmed by a prick-to-prick test with the maggots in both cases. The limited literature available on this subject supports the diagnosis.
