Pododermatitis macroscopic and microscopic characterization related to industrial classification of chicken feet for human consumption

ABSTRACT The aim of this study was to identify and classify pododermatitis in broilers, comparing the microscopic lesions with the macroscopic aspects used by the Sanitary Inspection. Broiler chicken feet were collected at a Poultry slaughterhouse under Sanitary Inspection, after classification according to the exportation standards. The chicken feet were randomly selected in each group, 30 feet type A, 30 feet type B and 33 feet type C. For the histopathological analysis, scores were developed according to the severity of the lesions, varying from 0 to 2. There was association (Chi-square, P摘要 本研究旨在识别并分类肉鸡足皮炎，并将显微镜下病变与卫生检验所用的宏观病变特征进行对比。研究样本采自一家接受卫生检验的家禽屠宰场的肉鸡鸡爪，所有样本均已按照出口标准完成分类。各组鸡爪均经随机抽取：A型30份、B型30份、C型33份。为开展组织病理学分析，研究人员根据病变严重程度制定了评分体系，评分范围为0至2分。本研究发现存在相关性（卡方检验，P
