A mortality follow up study was conducted among 7261 white female members in a local meatcutter's union in Baltimore, Maryland, between July 1949 and December 1980. The group was divided into four main job categories within the meat industry and a control group of non-meat workers belonging to the same union. Mortality in each of these subgroups was compared with that of white women in the United States general population through the determination of cause specific standardised mortality ratios. No increased risk of death from non-malignant causes was observed in any job category within the meat industry. Some caution should, however, be exercised in interpretating this finding, as few workers in chicken slaughtering plants died.
1949年7月至1980年12月期间，在马里兰州巴尔的摩市当地肉类切割工人工会的7261名白人女性会员中进行了一项死亡率随访研究。该群体在肉类行业内分为四个主要工作类别，并设立了一个属于同一工会的非肉类工人对照组。通过确定特定病因的标准化死亡率，将这些亚组中的每一组的死亡率与美国普通人群中的白人女性死亡率进行比较。在肉类行业的任何工作类别中，均未观察到非恶性病因导致的死亡风险增加。然而，在解释这一发现时应谨慎，因为在鸡肉屠宰厂工作的工人死亡人数很少。
