Abstract

Histological analyses of toe lesions for commercial broiler at the slaughterhouse of Pollo Olympico S.A., Colombia. Nova [online]. 2014, vol.12, n.22, pp.187-193. ISSN 1794-2470.

Objetive: To conduct histological analyses of toe lesions for commercial broiler at the slaughterhouse of Pollo Olympico S.A., Colombia, with the ultimate goal of proposing recommendations about sanitary containment. Materials and Methods: Poultry subjects were sampled in 10 farms of Pollo Olympico S.A. Macroscopic inspections were conducted on 129.551 animals while the microscopic ones were on 330 toe lesions. Histological analyses evaluated type and depth of inflammatory lesions as well as the presence of fungal infections Results: Macroscopic analyses revealed inflammatory process mediated by heterophiles (73,1%), mixed infiltrates (19%) and mononuclear (7.9%). Lesions were mainly localized at the sub-corneal level (77.9%) and showed no signs of fungal structures, giant cells or vascular presence.

Keywords : bird toe-pad-dermatitis; food safety assessment; containment at slaughterhouses; morphology of inflamatory lesions.
