“…The cultivation of greenhouse flowers and/or ornamental plants emerged as a significant risk factor for bronchial asthma in the European Farmers' Study (8), which focused on the prevalence and risk factors for airway obstruction in farmers and agriculture workers (8)(9)(10). Previous work on greenhouse growers has found a high prevalence of respiratory symptoms when compared with control populations (11), and occupational asthma to Tetranychus urticae , a macroscopic mite that may infest a wide range of plants, has been occasionally reported in these growers (12)(13)(14). Such reports, however, have focused on greenhouse workers cultivating vegetables and tomatoes and have included only flower growers cultivat-ing Dianthus caryophyllus.…”

The objective of this study was to determine the prevalence of occupational asthma and sensitization to workplace allergens in greenhouse flower and/or ornamental plant growers. A random sample of 40 growers who cultivated such crops and had participated in the European Farmers' Study was selected for a cross-sectional study that included (1) greenhouse characteristics and air contaminants (dust, endotoxin, and microorganisms), (2) respiratory symptoms, (3) occupational asthma diagnosed by bronchial provocation challenge, and (4) sensitization to workplace flowers or molds. Associations among respiratory symptoms, sensitization, greenhouse characteristics, and air contaminants were analyzed by logistic regression modeling. Thirty-nine growers agreed to participate (response rate, 97.5%). Bronchial provocation challenge confirmed occupational asthma in three workers (7.7%), all of them sensitized to workplace flowers or molds. No cases of occupational asthma were found among nonsensitized growers. Poor ventilation proved to be a marginal risk factor for wheezing (air velocity: odds ratio, 0.11; 95% confidence interval, 0.01-1.04). Sensitization to flowers or molds was found in 13 of 38 growers (34.2%) but was not related to greenhouse characteristics. We conclude that one-fourth of greenhouse flower and/or ornamental plant growers sensitized to workplace flowers or molds have occupational asthma, a disease that is suffered by 8% of the growers who cultivate these crops.

“…9,10 All previous TSM-related reports have been confined to occupational exposures. [2][3][4][5][6][7][8] Although house-dust mite (HDM) has been known as the most important allergen in Korea, 11 a recent investigation demonstrated that TSM could be one of the prevalent inhalant allergens in nonfarmers as well as farmers in pear orchards. 12 Skin prick test (SPT) results of adult asthmatic patients complaining of summer-type asthma indicated that TSM was second in prevalence of sensitivity to HDM.…”

Occupational airway sensitizers: an overview on the respective literature

Background Worldwide, there is rigorous scientific activity concerning the further development of work safety regulations involving airway‐sensitizing substances. Technical directives on hazardous substances are enforced in several countries and are being continuously updated. The European Union has established a code for several occupational substances, now labeled R 42 (“may cause sensitization by inhalation”). Methods We present an overview of the literature dealing with allergic occupational asthma. The literature was selected according to criteria of study design and diagnostic test methods. Approximately 300 publications were reviewed including both epidemiological studies and individual case reports. Results Airway sensitizers are systematically arranged and separately listed according to chemicals and their origin from animals, plants, and microorganisms. The clinical data as well as threshold limit values (TLV) and R 42 labeling of 250 airway‐sensitizing substances are presented. Conclusions The most common sensitizing substances causing occupational asthma were dust of cereal flours, enzymes, natural rubber latex, laboratory animals as well as low molecular substances such as isocyanates and acid anhydrides.

Occupational allergy in greenhouse workers: sensitization to Tetranychus urticae

Abstract: TU could be an important occupational allergen in greenhouse workers showing allergic symptomatology. There is no crossreactivity between this mite and the house dust mite D. pteronyssinus.
