Liquid manure storage is a common component of confinement systems for swine, beef, dairy, and veal operations. A mail questionnaire to a sample of swine producers indicated that more than 85,000 people in Iowa and an estimated 500,000 in the United States work in livestock confinement systems that use liquid manure storage. Deaths and illnesses in people with acute exposure to toxic gases emanating from the liquid manure have been recently reported. This communication reports results of the investigation of six such incidents. Hydrogen sulfide appears to be the main toxic substance involved, and agitation of the liquid manure is important in creating an acutely severely toxic environment. Preventive measures must include worker education and limitation of human exposure through control of environmental and human factors.
液体粪便储存是猪、牛、奶牛和犊牛养殖场圈养系统的常见组成部分。对一部分养猪户进行的邮件问卷调查显示，爱荷华州有超过85000人，美国估计有50万人在使用液体粪便储存的牲畜圈养系统中工作。最近有报告称，有人因急性接触液体粪便释放的有毒气体而死亡和患病。本通讯报道了对六起此类事件的调查结果。硫化氢似乎是主要的有毒物质，搅动液体粪便对于营造急性剧毒环境很重要。预防措施必须包括对工人进行教育，并通过控制环境和人为因素来限制人员接触。
