在美国，封闭的食用动物操作产生的废物量是美国污水处理厂产生的人类生物固体的40倍以上。与生物固体不同，生物固体必须符合病原体水平、减少病媒吸引力和金属含量的监管标准，而畜牧业废物则不需要处理。这一遗漏令人关切，因为过去50年来畜牧业生产发生了巨大变化，导致动物废物大量增加，以及与工业化食用动物生产的区域增长有关的废物在地理上高度集中。监管措施没有跟上这些变化的步伐。本文的目的是：1）审查影响美国食用动物废物生产的趋势，2）评估与食用动物废物相关的风险，3）将食用动物废物管理实践与生物固体管理实践进行对比，4）根据现有和潜在的政策选择提出建议，以改善食用动物废物的管理。
Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic changes in livestock production over the past 50 years, which have resulted in large increases in animal waste and a high degree of geographic concentration of waste associated with the regional growth of industrial food-animal production. Regulatory measures have not kept pace with these changes. The purpose of this paper is to: 1) review trends that affect food-animal waste production in the United States, 2) assess risks associated with food-animal wastes, 3) contrast food-animal waste management practices to management practices for biosolids and 4) make recommendations based on existing and potential policy options to improve management of food-animal waste.
