片吸虫病是一种经食物和水传播的人畜共患传染病，与反刍动物生产的巨大经济损失有关。为了确定秘鲁中央安第斯山脉一家屠宰场因肝片吸虫病而导致牛肝死亡的流行程度，我们评估了位于海拔3300米的环卡尤一家授权屠宰场16个月的记录。随后，还估计了死脏和死尸的平均重量，以确定直接和间接的经济损失。肝片吸虫病是肝损害的主要原因，患病率为55.72%(3926/7046；可信区间95%：56.88~54.56%)。在此期间，被感染的肝脏数量是供应给市场的肝脏数量的两倍多。虽然秘鲁安第斯山脉的肝脏平均价格非常便宜，但大约有16.45吨肝脏被毁，估计直接经济损失为35,080美元(可信区间95%：29,178-40,938美元)。体重增加减少(使用健康动物身体平均重量的10%计算)造成的间接损失估计为354,570美元(可信区间95%：387,908-321,227美元)。肝片吸虫病是一种重要的人畜共患病，威胁安第斯地区的粮食安全，对畜牧业的收入和廉价蛋白质来源的可获得性产生重大影响。
Fasciolosis is a zoonotic food- and waterborne infection related to great economic losses on ruminant production. In order to determine the prevalence of bovine liver condemnations due to fasciolosis in an abattoir at the Central Andes of Peru, we evaluated the records of an authorized slaughterhouse in Huancayo, at 3300 m above sea level, over 16 months. Subsequently, the average weights of condemned viscera and carcasses were also estimated to determine the direct and indirect economic losses. Fasciolosis was the main cause of liver condemnation, with a prevalence of 55.72% (3926/7046; CI 95%: 56.88-54.56%). The livers infected were more than double the amount of livers supplied to markets in this period. Although the average price of liver in the Peruvian Andes is very cheap, approximately 16.45 tons of livers were destroyed, estimating a direct economic loss of US$ 35,080 (CI 95%: US$ 29,178-40,938). The indirect loss due to decreased body weight gain (calculated using 10% of the average weight of a healthy animal carcass) was estimated at US$ 354,570 (CI 95%: US$ 387,908-US$ 321,227). Fasciolosis is an important zoonotic disease that threatens food security in the Andean region, with major repercussions on the income of the livestock industry and the availability of cheap protein sources.
