Case report. Monascus purpureus--a new fungus of allergologic relevance

Mycoses. 2002 Feb;45(1-2):58-60.


Anaphylactic reactions to food containing allergens in the consumption or preparation of food are well known. However, allergy in the preparation of sausages has rarely been described. In the present study a 26-year-old-butcher was investigated who had a severe anaphylactic reaction developing sneezing, rhinitis, conjunctivitis, generalised pruritus, followed by widespread urticaria, Quincke's oedema and dyspnoe after starting to prepare sausages containing red yield rice. Red yield rice is produced by the fungus Monascus purpureus. It was the first time that Monascus purpureus could be shown as allergic agent by means of prick-to-prick test, Cellular Antigen Stimulation Test (CAST) and different immunoblots.
