The relationship between occupation and exposure to several occupational agents and Hodgkin's disease (HD) was investigated in a case-control study of 152 cases and 613 controls with acute diseases ...admitted to all hospitals in Pordenone province, north-east Italy. Among cases, there was a significant excess of individuals occupied in agriculture (odds ratio, OR for greater than 10 years = 2.2, 95% confidence interval, CI:1.3-3.7), who were exposed to livestock and meat processing (OR = 3.4, 95% CI:1.7-6.6), herbicides and pesticides (OR = 3.2, 95% CI:1.6-6.5). When the relationship between agriculture and specific exposures was assessed, it appeared that contact with some still unidentified animal-related agent involved in livestock farming and meat processing may be at least as important in determining HD risk as exposure to herbicides and pesticides and, probably, more important than occupation in agriculture per se.
