The International Chemical Workers Union requested an evaluation be made of the health status of employees at the Continental Coffee Products Company (SIC-209S), Houston, Texas with particular attention given to potential exposure to pesticide residues on imported coffee beans. Analysis of air samples revealed the following concentration ranges: 29 personal respirable dust samples ranging from 0.03 to 2.03 milligrams/cubic meter (mg/m3); 27 of 28 personal total dust samples, 0.09 to 2.65 mg/m3; four area respirable dust samples, 0.11 to 0.53 mg/m3; and four area total dust samples, 0.16 to 2.39 mg/m3. Pesticide exposures were significantly below acceptable daily intakes. Of the 147 employees, 132 returned completed questionnaires. Employees with the greatest potential for exposure to coffee and tea dust reported acute irritant symptoms two to four times as frequently as others. The authors conclude that it would not be expected that employees would be exposed to pesticide levels posing an appreciable threat to health. There appears to be an increase in acute irritant (possible allergenic) symptoms in workers with the greatest potential for exposure to organic dusts. Recommendations were made to increase the use of local exhaust ventilation; to improve work practices to reduce generation of dust and accumulation; to increase ventilation in the basement re-mix operation; and train employees toward the understanding of potential hazards and their role in controlling dust.
