The study investigated the risks arising from application of pig slurry to soil in relation to viability of Salmonella typhimurium, Escherichia coli, total coliforms, faecal enterococci and eggs of Ascaris suum at different temperatures. Potential effect of changes in physico-chemical parameters, particularly dry matter (DM), pH and ammonia, were also investigated. Examination showed that S. typhimurium was devitalised after storage in the slurry for 115 days at 4 °C and after 90 days at 20 and 42 °C. Devitalization of E. coli and faecal entrerococci required more than 115 at temperature of 4 °C and faecal enterococci were recovered from slurry after 115 days of storage even at temperature of 20 °C. Total coliforms survived for 115 days at all investigated temperatures. Complete devitalization of A. suum eggs was not achieved even after 115 days at 42 °C. Our investigations indicated potential microbial and parasitic risk related to application of pig slurry to soil even after 115 days of storage.
本研究调查了与猪粪施用于土壤相关的风险，涉及沙门氏菌、大肠杆菌、总大肠菌群、粪肠球菌和猪蛔虫卵在不同温度下的存活能力。还研究了物理化学参数变化的潜在影响，特别是干物质（DM）、pH 值和氨。检查表明，在 4°C 下储存 115 天后，在 20°C 和 42°C 下储存 90 天后，鼠伤寒沙门氏菌失去活力。大肠杆菌和粪肠球菌需要在 4°C 下储存超过 115 天才会失去活力，即使在 20°C 下，粪肠球菌也能从粪便中回收。总大肠菌群在所有研究温度下存活 115 天。即使在 42°C 下储存 115 天，猪蛔虫卵也未能完全失活。我们的研究表明，即使在猪粪储存 115 天后，仍存在与猪粪施用于土壤相关的微生物和寄生虫风险。
