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< 0.05) between the macroscopic classification (A, B and C) and histological changes (0, 1 and 2). The A classification differed significantly (ANOVA, Tukey-Kramer, P< 0.05) from the B and C classifications regarding the histopathological scores observed. There was no difference in feet lesions that justified the separation between the feet classified in B and C, since both presented a linear delimitation of the lesions, suggesting superficiality and restriction to the keratinized epithelium. Therefore, the use of the feet for human consumption after mechanical removal of the footpad lesions is suggested since the product does not pose risks to the consumer.
