Food animals though sources of protein and revenue to man, also serve as vehicles of disease transmission. This work reviews a three year record of slaughtered cattle in 12 abattoirs/slaughter slabs in western Nigeria to determine the economic and public health issues associated with their disease conditions. Out of 641,224 cattle slaughtered, 51,196 (7.98%) were attributable to 14 diseases/conditions including tuberculosis, pneumonia, fascioliasis, pimply gut, paramphistomosis, cysticercosis, dermatophilosis, tonsillitis, taeniasis, ascariosis, abscess, mange, mastitis and immature fetuses. Pneumonia (21.38%), fascioliasis (20.28%) and tuberculosis (7.95%) were major reasons for condemnations; least being ascariosis (0.01%). The lungs (45.66%) and liver (32.94%) accounted for most organ condemned while the heart (0.02%) was the least affected. The proportions of pneumonia, fascioliasis and immature fetuses observed were not statistically different (Mean = 3895.7; 3654.0; 3467.3); however, a significant difference existed with other conditions (Mean(A) = 3895.7; 3654.0; 3467.3; Mean(B) = 1359.7; 1057.7; 510.3). Organs/offal condemnations constituted loss of revenue and animal protein as 124,333 kilogrammes worth of meat valued in Naira at N41,613,043 ($332,904) was lost over the period giving an average of N13,871,014 ($110,968) annually. This, coupled with fetal wastage represented an economic loss; with associated public health implications.
食用动物虽然是人类蛋白质和收入的来源，但也是疾病传播的载体。这项工作回顾了尼日利亚西部12个屠宰场/屠宰板三年来屠宰牛的记录，以确定与其疾病状况相关的经济和公共卫生问题。在屠宰的641,224头牛中，51,196头（7.98%）归因于14种疾病/状况，包括结核病、肺炎、片形吸虫病、丘疹性肠道疾病、双口吸虫病、囊尾蚴病、嗜皮菌病、扁桃体炎、绦虫病、蛔虫病、脓肿、疥癣、乳腺炎和未成熟胎儿。肺炎（21.38%）、片形吸虫病（20.28%）和结核病（7.95%）是主要的废弃原因；最少的是蛔虫病（0.01%）。肺部（45.66%）和肝脏（32.94%）是被废弃最多的器官，而心脏（0.02%）受影响最小。观察到的肺炎、片形吸虫病和未成熟胎儿的比例没有统计学差异（平均值 = 3895.7；3654.0；3467.3）；然而，与其他状况存在显著差异（平均值(A) = 3895.7；3654.0；3467.3；平均值(B) = 1359.7；1057.7；510.3）。器官/内脏的废弃造成了收入和动物蛋白的损失，在此期间损失了价值41,613,043奈拉（332,904美元）的124,333公斤肉类，平均每年损失13,871,014奈拉（110,968美元）。这与胎儿流产一起造成了经济损失，并带来了相关的公共卫生问题。
