为保障康乐海滩泳客的健康，署方会采用粪便细菌指标标准监测水质，而超过标准的水质将会关闭。然而，海滩游人也接触到海滩沙子，其卫生质量不包括在海滩监测计划中。事实上，沙子和沉积物提供了栖息地，在沿海地区，粪便细菌种群可能会持续存在，在某些情况下还会生长。在海滩沙子和沉积物中对特定病原体的研究较少，但有大量证据表明，它们也可能在这些环境中持续存在。本文综述了不同气候区和受不同程度人为影响的海滩沙中粪便指示菌和病原菌丰度和分布的研究现状。在所有地区，粪便指示剂细菌在海滩沙中几乎无处不在，在干沙、淹没沙和水中的粪便指示剂丰度之间出现了类似的关系。综上所述，这些研究确定了一个潜在的公共卫生问题的背景，并确定了必须解决的研究问题，以支持未来的政策决策。
To protect bather health at recreational beaches, fecal indicator bacterial standards are used to monitor water quality, and waters exceeding the standards are subsequently closed to bathers. However beachgoers are also in contact with beach sands, the sanitary quality of which is not included within beach monitoring programs. In fact, sands and sediments provide habitat where fecal bacterial populations may persist, and in some cases grow, in the coastal zone. Specific pathogens are less well studied in beach sands and sediments, but there is a body of evidence that they too may persist in these environments. This paper reviews the current state of knowledge regarding the abundance and distribution of fecal indicator bacteria and pathogens in beach sands of diverse climatological regions, and at beaches subjected to varied levels of anthropogenic impact. In all regions fecal indicator bacteria are nearly ubiquitous in beach sands, and similar relationships emerge between fecal indicator abundance in dry sand, submerged sands, and water. Taken together, these studies contextualize a potential public health issue and identify research questions that must be addressed in order to support future policy decisions.
