A study was conducted among 13,844 members of a meat-cutter's union, from July 1949 to December 1980, to examine cancer occurrence in the meat industry. Separate analyses were carried out for the whole group, and for subgroups defined by job-categories characteristic of the industry, including a control group. Mortality was compared with that of the United States through the estimation of standardized mortality ratios (SMR) and proportional mortality ratios. A statistically significant proportional mortality ratio of 2.9 was obtained for Hodgkin's disease among abattoir workers; the SMR of 2.2 was not significant. Among meat-packing plant workers, highly statistically significant SMRs were recorded for bone cancer, SMR = 9.6; cancer of the buccal cavity and pharynx, SMR = 3.4; and lung cancer, SMR = 1.9. The role of oncogenic viruses and other carcinogenic exposures was investigated.
1949年7月至1980年12月期间，对一个肉类切割工人工会的13844名成员进行了一项研究，以调查肉类行业中的癌症发生情况。对整个群体以及按该行业特有的工作类别定义的亚组（包括一个对照组）进行了单独分析。通过估计标准化死亡率（SMR）和比例死亡率，将死亡率与美国的死亡率进行了比较。屠宰场工人中霍奇金病的比例死亡率为2.9，具有统计学意义；SMR为2.2，无统计学意义。在肉类包装厂工人中，骨癌的SMR为9.6；口腔和咽癌的SMR为3.4；肺癌的SMR为1.9，均具有高度统计学意义。对致癌病毒和其他致癌暴露的作用进行了调查。
