Índice de ocorrência e índice sazonal ajustado de condenações de vísceras suínas em frigorífico localizado no Triângulo-Mineiro

Abstract

Brazil is a global reference in agribusiness, standing out in the production and exportation of agricultural products. Among the animal protein produced, pork meat deserves special attention as it is the segment with the greatest potential for growth in production, exportation, and consumption. This positive performance relies heavily on the action of official sanitary inspection services and the proper utilization of data regarding condemnations and deviations occurring in the slaughter line to mitigate losses for the supply chain. Therefore, this study aimed to evaluate the occurrence index and adjusted seasonal index of condemnations of pork viscera at a slaughterhouse located in the Triângulo Mineiro region between 2019 and 2021. For this evaluation, condemnation data generated by the Municipal Inspection Service (SIM) was consulted to obtain the number of slaughtered animals, date of slaughter, number and cause of viscera condemnation. The condemnation data was assessed using the Condemnation Occurrence Index (COI), Adjusted Seasonal Index (ASI), and subjected to the Spearman correlation test classified as: very high, high, medium, low and very low. The results allow us to conclude that the lungs and liver contributed to over 45% of total viscera condemnations and the viscera marketed by the establishment (heart, tongue, liver and kidneys) contributed with 123,642 condemnations. The COI per 100 slaughterings ranged from 1.9 for tongue condemnations in October 2021 to 31.46 for liver condemnations in June 2021. With the exception of the liver, there was no trend of increasing or decreasing COI for the viscera. Additionally, there was no significant variation in the ASI between the months of the year for any of the evaluated viscera. None of the marketed viscera showed a very high correlation (-0,9 ≥ r or r ≥ 0.9), however, the liver, spleen, and lungs exhibited a high correlation (±0.7 ≤ r < ±0.9) in their condemnations. It is concluded that among the viscera marketed by the establishment, the only one showing a trend towards increasing COI is the liver, and there are no influences of seasonality on the condemnation rate of marketed viscera despite deviations when comparing monthly averages with the expected average for the year. The correlation between condemnations was only high between the liver, spleen, and lungs.
