BOHRF Original Authors' Main Conclusions

The original authors' main conclusions are taken from Abstract, Results and Discussion. They are decided upon by the authors of the BOHRF occupational asthma guidelines and form part of the guidelines.

During crab-processing season, asthma-like symptoms developed in 26% of study participants. Only 9% of those with new asthma-like symptoms were IgE-sensitised to crab at the end of the season. Among the crab-processing jobs, butchering and degilling workers had the highest incidence of respiratory symptoms. Both personal and process-related factors appear to affect the development of respiratory symptoms in crab-processing workers. In univariate analysis for associated factors, a statistically significant association with family history of allergies and elevated eosinophil cationic protein was found. Smoking did not reach statistical significance.
