Study of heart, liver and lung condemnations occurred in Santarém, Pará, during the year 2018

Abstract

The objective was to verify the occurrence of convictions of red viscera (liver, heart and lung) in cattle slaughtered in the municipality of Santarém, Pará, Brazil. For the elaboration of the research, weekly technical visits were carried out to obtain data on hygienic, sanitary and technological inspection. During the evaluated period, about 28,000 cattle were slaughtered, of which, in 22.69%, at least one type of cause / lesion that was determinant for partial or total disposal was identified. The lung was the organ that had the highest rates of condemnation with 58.55%, followed by the liver with 31.94% and the heart with 9.51%. The main causes of lung disorders were pulmonary emphysema, which accounted for 65.33% of the discards of these viscera, followed by ruminal aspiration (13.19%) and congestion (8.9%). In the liver, telangiectasia was the one with the highest discard rate with 32.06%, followed by cirrhosis (27.83) and contamination (14.18%). In the heart, contamination resulted in the largest number of discards, accounting for 50.82%, accompanied by pericarditis with 45.19%, and tuberculosis (2.64%). In this study, the economic losses identified by the condemnation of the lung, liver and heart would correspond, in current values, to R $ 241,701.99. Individually the liver provided greater economic loss (R $ 142,709.00), followed by the lung (R $ 85,396.95) and, finally, the heart (R $ 13,596.04). Given the above, this scenario creates an alert and highlights the need for strict quality control programs in order to mitigate the economic impacts arising from the condemnation of offal.
