Records were collected for Taenia saginata cysticercosis infections in cattle slaughtered at the Cold Storage Company Abattoir in Bulawayo, Zimbabwe, between January 2006 and December 2007. The cattle were drawn from the two Matabeleland provinces in the dry western and southern parts of the country. A total of 86,080 cattle were slaughtered during the period. The average prevalence of T. saginata cysticercosis was found to be 1.6% (n = 1 364) with Matabeleland North having a higher prevalence of 2.8% (n = 629) and Matabeleland South 1.2% (n = 735). There were no significant seasonal differences (p > 0.05) in incidences of T. saginata cysticercosis during the study although numerically, the prevalence of T. saginata cysticercosis was higher in the wet season. There was no significant difference (p > 0.05) in the prevalence of T. saginata cysticercosis in different age classes of cattle slaughtered. Of the infected carcasses, a great proportion of these had live cysts (1.4%) while few had dead cysts (0.2%). Most of the cattle condemned were below the age of 2 years and some were full adults (p < 0.05). There was a significant association between farm type (p < 0.05) and prevalence of T. saginata cysticercosis with most infections being observed in the communal farming system. Though the prevalence of T. saginata cysticercosis appears to be low, there is a need to conscientize the farmers to avoid losses due to carcasses condemnation at slaughter houses which will have a negative financial impact to the individual farmer. There is also a need to investigate such cases even further to reduce zoonotic consequences due to the undetected cases in communal areas.
收集了2006年1月至2007年12月在津巴布韦布拉瓦约冷库公司屠宰场屠宰的牛的牛带绦虫囊尾蚴病感染记录。这些牛来自该国西部和南部干旱地区的两个马塔贝莱兰省。在此期间，共屠宰了86,080头牛。发现牛带绦虫囊尾蚴病的平均患病率为1.6%（n = 1364），其中北马塔贝莱兰患病率较高，为2.8%（n = 629），南马塔贝莱兰为1.2%（n = 735）。在研究期间，牛带绦虫囊尾蚴病的发病率没有显著的季节性差异（p > 0.05），尽管从数字上看，牛带绦虫囊尾蚴病的患病率在雨季较高。在屠宰的不同年龄组的牛中，牛带绦虫囊尾蚴病的患病率没有显著差异（p > 0.05）。在受感染的胴体中，很大一部分有活囊尾蚴（1.4%），而很少有死囊尾蚴（0.2%）。大多数被判定不合格的牛年龄在2岁以下，有些是成年牛（p < 0.05）。农场类型与牛带绦虫囊尾蚴病的患病率之间存在显著关联（p < 0.05），大多数感染发生在社区农业系统中。尽管牛带绦虫囊尾蚴病的患病率似乎较低，但有必要提高农民的认识，以避免因屠宰场胴体被判不合格而造成损失，这将对个体农民产生负面的经济影响。还需要进一步调查此类病例，以减少由于社区地区未检测到的病例而导致的人畜共患病后果。
