Self reported and company recorded exposure information for structural fumigation workers were compared. The study was also to determine whether reasonable summary measures of exposure could be calculated for each fumigation worker. Thirty two workers from 15 companies participated in the study which was part of a cross sectional medical study and involved a questionnaire to assess duration and frequency of exposure based on a self reported work history. Ten of the workers reported working as a shooter and 28 as a tent crew worker during the 2 weeks prior to their examination. Self reported and company recorded data showed adequate correlation, except for the tent crew worker estimates of days worked over the 2 weeks preceding the study. Evidence of the poor correlation among tent crew workers and the days worked was found in the statistically significant paired differences between self reported and company recorded estimates. Three other variables between self reported and company records also noted were total years employed in the fumigation industry, days worked by shooters, and mean tarp dismantling jobs performed per day by tent crew workers. The authors acknowledge that both self reported exposure data and data from company records have potential limitations. This study shows both the difficulty of validating exposures within cohorts of workers employed in industries characterized by small, independent companies, and the need for improved maintenance of job history records by these companies.
