There is a high prevalence of work-related respiratory symptoms (53.8%) in bell pepper horticulture. Groenewoud  et al (2002) estimated in two-thirds of the employees, symptoms at work were associated with an IgE-mediated allergy due to the high and chronic exposure to bell pepper pollen. Complaints at work without specific sensitization to bell pepper pollen can be caused by non-specific hyper-reactivity or atopy to other occupational allergens. The extent of this occupational allergy has important consequences for the health care of this large, still growing occupational group [1]. The predatory mite Amblyseius cucumeris (Ac) appears to be an important occupational allergen in bell pepper horticulture next to the bell pepper pollen. As many as 23% of the greenhouse employees in this study showed a positive SPT result to this mite[2],


2009 Rüger RD et al
reported on a patient with rare anaphylaxis after ingestion of raw bell pepper. A complex cluster of sensitization including grass and birch pointed out a possible pollen-associated food allergy. We suggest that the severe reaction is due to cross-reactivity towards Bet v 1. Western blot showed binding of the patient's serum to an 11 kDa protein, which has not been described yet and might be a new allergenic structure of the bell pepper plant or a fragment of the Bet v 1-homologous bell pepper protein.
