South Africa's livestock population is rapidly evolving and consequently will require sustained epidemiological surveillance to detect and prevent diseases which contribute to a decrease in livestock productivity, public health risk and food wastage. infection is one of the commonest diseases affecting livestock health and a significant portion of meat and offal's are declared unfit for human consumption. This study assessed the prevalence and monetary losses associated with infection at three abattoirs in Eastern Cape Province. A retrospective data of all slaughtered cattle were obtained from Department of Rural Development and Agrarian Reform (DRDAR) from 2010-2012. A prospective abattoir survey was conducted between July 2013 and June 2014 to determine the prevalence and financial loss due to fasciolosis. The highest prevalence was in December and January (23%) while the lowest prevalence was recorded in May and June (5%). Annual prevalence of at abattoirs AB1, were (3.2%, 2.2% and 2.0%), AB2 (6.4%, 4.6% and 3.5%), AB3 (14.4%, 6.9% and 9.5%) for year 2010, 2011 and 2012 respectively. The total financial loss due to infection during the active survey of the three abattoirs was ZAR 44, 930 (3456.2 USD). A breakdown of this figure shows that whole liver condemnation was ZAR 25, 230 (2, 357 USD), and partial liver condemnation was ZAR 19, 700 (1515.4 USD). The present study reveals the economic loss due to liver condemnation from infection and provides regional baseline information regarding the prevalence of in cattle at three abattoirs.
南非的牲畜数量正在迅速演变，因此需要持续的流行病学监测，以发现和预防导致牲畜生产力下降、公共卫生风险和食物浪费的疾病。感染是影响牲畜健康的最常见疾病之一，相当一部分肉类和内脏被宣布不适于人类食用。本研究评估了东开普省三个屠宰场与感染相关的患病率和货币损失。从农村发展和土地改革部（DRDAR）获取了2010年至2012年所有屠宰牛的回顾性数据。2013年7月至2014年6月进行了一项前瞻性屠宰场调查，以确定肝片吸虫病的患病率和经济损失。患病率最高的是12月和1月（23%），而患病率最低的是5月和6月（5%）。2010年、2011年和2012年，屠宰场AB1的年患病率分别为（3.2%、2.2%和2.0%），AB2为（6.4%、4.6%和3.5%），AB3为（14.4%、6.9%和9.5%）。在对三个屠宰场的积极调查期间，感染造成的总经济损失为44,930兰特（3456.2美元）。这一数字的细目显示，全肝被判不合格为25,230兰特（2357美元），部分肝被判不合格为19,700兰特（1515.4美元）。本研究揭示了肝片吸虫病感染导致的肝脏被判不合格造成的经济损失，并提供了关于三个屠宰场牛群中肝片吸虫病患病率的区域基线信息。
