Porcine Cysticercosis (PC) infection is globally classified as a neglected and re-emerging tropical disease. The disease is endemic in Western Kenya yet smallholder farmers continue to practice scavenging pig production, thereby posing public health risk. This study determined the prevalence of PC infection at the farms and slaughter slabs in a cross-sectional survey in two Counties (Busia and Kakamega) of Western Kenya.
Two hundred and eighty-seven (287) heparinized blood samples were collected at the farm from 162 households in 9 villages and 113 pigs from 5 slaughter slabs. The prevalence of PC was detected through meat inspection at slaughter slabs, and the prevalence of antigen determined by using the ApDia Ag-ELISA test at the farms and slaughter slabs.
At meat inspection, the PC prevalence was 1.8%, while prevalence of cysts detected with Ag-ELISA test was 3.8% at the farms, and 5.3 % at the slaughter slabs. The Ag-ELISA test had sensitivity of 100% (95% CI: 19.79- 100.00) and specificity of 96.4% (95% CI: 90.49- 98.84).
The PC prevalence levels observed among scavenging pigs in Western Kenya should be a cause of public health risk concern. This observation warrant enforcing mandatory pig confinement, and use of latrines at the farms and meat inspection at local slaughter slabs. Further studies are recommended to identify different species in cysticercoids pigs in the region, which this study could not differentiate.
猪囊尾蚴病（PC）感染在全球被列为一种被忽视的重新出现的热带疾病。该疾病在肯尼亚西部流行，但小农户仍继续实行散养猪生产，从而带来公共卫生风险。本研究通过对肯尼亚西部两个县（布西亚和卡卡梅加）的横断面调查，确定了农场和屠宰场中PC感染的患病率。
从9个村庄的162户家庭的农场采集了287份肝素化血样，从5个屠宰场采集了113头猪的血样。通过屠宰场的肉类检查检测PC的患病率，并在农场和屠宰场使用ApDia Ag-ELISA试验测定抗原的患病率。
在肉类检查中，PC患病率为1.8%，而在农场使用Ag-ELISA试验检测到的囊肿患病率为3.8%，在屠宰场为5.3%。Ag-ELISA试验的灵敏度为100%（95%CI：19.79 - 100.00），特异性为96.4%（95%CI：90.49 - 98.84）。
在肯尼亚西部散养猪中观察到的PC患病率水平应引起对公共卫生风险的关注。这一观察结果需要强制实行猪的圈养，在农场使用厕所，并在当地屠宰场进行肉类检查。建议进一步研究以确定该地区囊尾蚴猪中的不同物种，本研究无法区分这些物种。
