“…1,5 Asthma prevalence among trawler workers was 3.9% and is consistent with previously reported asthma prevalence of between 2 and 8% in workers processing bony fish, irrespective of industry type. 19 Work-related COPD has previously been described in occupational environments where bioaerosols are an important exposure.…”

Objective: Respiratory outcomes and work-related factors were studied in two seafood worker populations representing different occupational environments. Methods: Levels of fractional exhaled nitric oxide (FE NO ), spirometric values, prevalence of respiratory symptoms, and self-evaluated exposures were compared between 139 Norwegian salmon workers and 127 Russian trawler workers. Results: Increased odds ratios (ORs) of shortness of breath with wheezing and prolonged cough as general respiratory symptoms were found in salmon workers, while increased ORs of work-related dry cough and running nose were found in trawler fishermen. Both worker groups ranked ''cold work environment,'' ''use of disinfectants,'' and ''contaminated indoor air'' as the first, second, and third most important causes of work-related respiratory symptoms, respectively. Fractional exhaled nitric oxide levels were higher in asthmatic trawler workers compared to asthmatic salmon workers. Conclusions: Respiratory symptoms commonly associated with obstructive airway diseases were more prevalent in salmon workers, while symptoms commonly associated with asthma and short-term effects of cold air exposure were more prevalent in trawler workers.

“…[1][2][3][4][5][6][7][8][9][10][11][12][13] However, little is known about the similarities and differences in symptom profiles and lung function outcomes in workers from different types of seafood workers. Negative respiratory effects may be associated with workplace and/or individual factors.…”

“…The lack of a relationship for respiratory sensitizers such as AA may be because those who develop symptoms tend to move out of highly exposed jobs. In support of this, a study of occupational asthma among salmon processors showed an inverse relationship between the risk of having occupational asthma and duration of exposure [28]. A relationship between cumulative exposure to AA and BHR cannot be completely excluded because there is bound to be misclassification of exposure in a study looking back over 30 yrs and misclassification would weaken any association [17].…”

Risk factors for bronchial hyperresponsiveness have previously been established in the general community. In settings where occupational asthma is a risk, it has not been established whether occupational sensitization or measures of exposure are important.Bronchial responsiveness to histamine was measured in a cohort of 506 workers exposed to acid anhydrides. Skin-prick tests were performed with conjugates of phthalic, maleic and trimellitic anhydride with human serum albumin and with common inhalant allergens. Employment and smoking histories were recorded. Occupational exposure was measured using personal air samplers and estimates of past exposure made by retrospective exposure assessment.Three hundred and seventy workers (73%) had bronchial responsiveness measured (median age 39 yrs, range 18±77) and 46 (12%) of these were hyperresponsive (provocative dose causing a 20% fall in forced expiratory volume in one second (FEV1; PD20) #8 mmol). Twelve (3%) of these responsive workers had a skin-prick test reaction to an acid anhydride conjugate, 124 (34%) to a common inhalant allergen, and 148 (40%) were current smokers. Multivariate analysis showed that occupational sensitization, sensitization to a common inhalant allergen, age, and pack-years of smoking were independent risk factors for bronchial hyperresponsiveness. Of these only occupational sensitization was completely independent of baseline FEV1.It is concluded that sensitization to acid anhydrides is a significant risk factor for bronchial hyperresponsiveness. However, measures of personal acid anhydride exposure were not associated with bronchial hyperresponsiveness. Eur Respir J 2000; 15: 710±715.

“…Gaddie et al [18] and Douglas et al [34] illustrated this in prawn-and salmon-processing plants, respectively, with no new cases of OA and fewer asthma symptoms after reduction of the atmospheric levels of the causing substances. Moreover, Gautrin et al [15] have shown in 2010 that cumulative exposure to snow crab allergens is positively associated with OA and allergy in a dose-response manner.…”

“…Occupational asthmatic reactions to salmon have been demonstrated with prevalence of 8% among automated salmon processing workers [34]. In a study including 70 workers of a Norwegian salmon-processing company, wheezing was noted in 5.7% on Mondays, and 7.1% of workers have been diagnosed with asthma [35].…”
