A health surveillance study of male grain food manufacturing workers used a respiratory health questionnaire and spirometry to assess the prevalence of work-related respiratory symptoms and impaired ventilatory performance.
The prevalence of cough, breathlessness, wheeze and chest tightness was between 8-13% but was 20% for rhinitis.
Rhinitis was the most common symptom with 37% of those reporting rhinitis describing this as work-related.
A case-control analysis of workers reporting rhinitis did not identify any specific occupational activities associated with increased risk of rhinitis.
Smoking habit and all respiratory symptoms apart from rhinitis had a significant effect upon ventilatory performance.
Occupational exposure to raw grains, flour, ingredients and finished food was categorized as high, medium or low in either continuous or intermediate patterns.
Multiple regression analysis confirmed the effects of height, age and smoking upon ventilatory performance.
However, occupational exposure to grain, flour, food ingredients and cooked food dusts had no effect upon ventilatory performance.
It is concluded that smoking habit is the major determinant of respiratory symptoms and impaired ventilatory function.
The excess complaints of rhinitis warrant further study but it would appear that the current occupational exposure limits for grain, flour, food ingredients and cooked food dusts are adequate to protect workers against impairment of ventilatory performance.
