An experiment using lysimeters suggested that the eggs of Taenia saginata and Ascaris lumbricoides survive for only a short time when applied to pasture in sewage sludge. However, a subsequent experiment which followed the survival of eggs throughout the soil profile demonstrated that some T. saginata eggs could still be found at 200 days on the soil surface, and that survival increased down the profile. Rainfall is shown to be able to wash eggs into the soil where they may be afforded protection from radiation and desiccation; this may have little epidemiological significance.
一项使用蒸渗仪的实验表明，当牛带绦虫和蛔虫的虫卵施用于牧场的污水污泥中时，它们只能存活很短的时间。然而，随后一项追踪虫卵在整个土壤剖面中存活情况的实验表明，在200天时仍能在土壤表面发现一些牛带绦虫虫卵，而且随着土壤深度增加，虫卵的存活率也有所提高。降雨能够将虫卵冲进土壤中，在那里它们可能受到辐射和干燥的保护；这可能在流行病学上意义不大。
