Abstract Reticuloendotheliosis viruses (REV) are a group of retroviruses similar to avian leukosis/sarcoma viruses (ALSV) that naturally infect and cause cancers in chickens. It was recently found that ALSV antibody levels were associated with job tasks in the poultry industry. The objectives of this study were to examine whether a similar association can be found with REV antibody levels and to examine the correlation between REV and ALSV antibody levels. Relative risk was estimated comparing REV antibody levels of 45 poultry workers with those of 44 controls. The expected mean antibody level was predicted for the association with employment by a generalized linear model. REV antibody levels were significantly higher in poultry workers than in control subjects and were associated with gender and employment conditions, especially employment duration. The relative risk was significantly higher for some job categories. A significant correlation was observed between REV and ALSV antibody levels, which was strong among poultry workers, but weak among the control subjects. Implications of these findings are discussed.
