Ecosan sludge reuse in agriculture poses microbial risks, increasing pathogen counts in crops. Viability reduction offers some safety, but Ecosan sludge revalorisation standards are crucial.

Area of Science:

  • Environmental microbiology
  • Agricultural science
  • Public health

Background:

  • Ecosan (ecological sanitation) systems generate sludge that can be a valuable soil amendment.
  • However, Ecosan sludge can harbor microbial pathogens, posing risks if not properly managed.
  • Assessing these risks is critical for safe agricultural reuse.

Purpose of the Study:

  • To evaluate the microbial risks associated with reusing Ecosan sludge in agriculture.
  • To quantify pathogen levels in crops treated with Ecosan sludge.
  • To inform the development of Ecosan sludge revalorisation standards.

Main Methods:

  • Analysis of Ecosan sludge from KwaZulu Natal, South Africa for helminth ova, faecal coliforms, faecal streptococci, and Salmonella spp.

  • Application of varying rates of sludge to spinach and carrots.
  • Quantification of microbial and helminth ova content in crops.

    • Main Results:

    • Sludge application increased bacterial and helminth ova counts in spinach and carrots.
    • Helminth ova content was higher in crop leaves than stems.
    • Pathogen viability in crops was reduced to 20-25%, mitigating disease risk.

    Conclusions:

    • Ecosan sludge reuse in agriculture presents significant microbial risks.
    • Developing Ecosan sludge revalorisation standards is essential for safe application.
    • Recommendations are provided considering sludge characteristics and rural conditions.
