EXAME MACROSCÓPICO DAS ARTICULAÇÕES DE SUÍNOS ARTRÍTICOS NO ABATEDOURO

Abstract

Realizou-se um estudo macroscópico das articulações dos membros torácicos e pélvicos
e respectivos linfonodos de suínos recém-abatidos em um matadouro localizado em Concórdia
SC. incluiu-se no presente estudo todos os suínos que foram desviados da linha de abate, por
suspeita de artrite. Dos 23.393 suínos abatidos, 140 (0,5%) foram desviados para o departamento
de inspeção final, por suspeita de artrite. Deste total constatou-se: 70% de artrite causada pela
osteocondrose, 21% artrite infecciosa, 3% artrite infecciosa e osteocondrose simultaneamente, 1%
apresentaram artrite traumática, 3% artrite sem diagnóstico conclusivo e 2% apresentaram-se com
as articulações normais. As artrites causadas pela osteocondrose caracterizaram-se pelo grande
volume de líquido sinovial e pelas áreas focais de dobras, abas e úlceras na cartilagem articular. As
artrites infecciosas caracterizaram-se pela reação nos linfonodos regionais e pela moderada a
acentuada hipertrofia da membrana sinovial. O percentual de artrite causada pela osteocondrose
foi superior ao encontrado em estudos anteriores e ressalta a necessidade de um diagnóstico
diferencial com as artrites infecciosas a fim de se evitar a condenação desnecessária de carcaças.

Macroscopic analysis of joints from arthritic swines pigs in the abattoir

Abstract

A macroscopic study of thoracic and pelvic limb articulations as well as regional
lymph nodes was performed in recently-slaughtered swines at a slaughterhouse located in Concordia,
SC, Brasil. A total of 23,393 carcasses were included in the study, 140 (0.5%) being diverted on the
discharge line by the Department of Final Inspection as suspicious for arthritis. The analysis of the
suspicious carcasses showed that 98 (70%) presented arthritis caused by ostechondrosis, 29 (21%)
infectious arthritis, four (3%) infectious arthritis and ostechondrosis simultaneously, two (1%) traumatic
arthritis, four (3%) presented arthritis with uncertain diagnosis and three (2%) showed normal
articulations. The arthritis caused by the osteochondrosis was diagnosed by the increased volume
of sinovial fluid and focal areas of folds, flaps and ulcers in the articular cartilage. The infectious
arthritis was diagnosed by an inflammatory process involving regional limph nodes and by moderate
to accentuated hypertrophy of the sinovial membrane. The percentage of arthritis caused by
osteochondrosis was higher when compared to those found in previous studies. This fact emphasizes
the need for a differential diagnosis between infectious arthritis and osteochondrosis in order to
avoid the unnecessary condemnation of carcasses at slaughterhouses.
