Time series evaluation of ascitic syndrome condemnation at poultry abattoirs under Federal Inspection Service of Brazil (2010-2019)

Abstract

Over the last decade, Brazil registered a 10.56% increase in the number of poultry slaughtered in establishments registered under the “Serviço de Inspeção Federal” (SIF - Federal Inspection Service), as a result of technological advances in management, health and genetics applied to national aviculture. At slaughter, during post-mortem inspection, carcasses can be totally or partially condemned for various reasons, including ascitic syndrome. This syndrome has economic implications for the industry, in addition to being a problem for the health and welfare of poultry. The objective of this work was to evaluate the historical series (2010-2019) of partial and total condemnations of poultry carcasses due to ascitic syndrome in slaughterhouses registered under the SIF and located in the main poultry-producing states. Through official data, the condemnation occurrence index (COI) and the adjusted seasonal index (ASI) were calculated. The condemnation rate was 1,140 carcasses condemned, totally or partially, for ascitic syndrome for every 1,000,000 poultry slaughtered. The smallest and largest COIs were found in São Paulo (February 2010) and in Goiás (January 2017), respectively. The occurrence of condemnations for this syndrome was cyclical throughout the historical series, showing peaks of condemnation in all years evaluated, with the highest ASIs in July, August and September, and with rates varying between 1.24 and 1.54 in these months. Considering the period of pre-slaughter housing, the highest ASIs coincide with the coldest period of the year (May to August) for all analyzed states. The results show that ascitic syndrome is a growing problem in Brazil, with greater occurrence during the coldest months of the year, having a negative impact on animal health and the profitability of producers and industries in the poultry production chain.

Time series evaluation of condemnation at export poultry slaughterhouses in southeastern Brazil (2009– 2019): a tool for optimizing resources in the poultry production chain

“…In the present study, the only cause of condemnation for non-technological failures with an ASI difference was an ascitic syndrome, with the highest values identified in the months of July to October (P < 0.05) (Graph 3). A similar result was found by Souza et al (2021) who, analyzing the states with the highest poultry production in Brazil, identified the highest ASIs from July to September. These variations in ASI values can be explained by the fact that ascitic syndrome is a metabolic syndrome, which is caused by interactions between diet, genetic, and environmental factors (altitude and temperature) (Baghbanzadeh and Decuypere, 2008;Olkowski et al, 2003).…”

“…These trends reflect technologies used, sanitary conditions of the batch, and employee training policies. (Muchon et al, 2019;Souza et al, 2021;Souza et al, 2018). Therefore, the proper recording and analysis of the occurrences of condemnation in a slaughterhouse are essential for the planning of preventive measures, aiming at economic gains for the meat supply chain (Saraiva et al, 2021;Schulze Bernd et al, 2020).…”

“…Among their responsibilities, the official veterinarian is responsible for inputting the daily condemnation data into the Management Information System of the Federal Inspection Service (MISFIS) (BRASIL, 1998(BRASIL, , 2017. Considering the importance of Brazil as a global producer and supplier of animal protein, studies have used these data to analyze and propose improvements to the sector (Muchon et al, 2019;Souza et al, 2018;Souza et al, 2021).…”

“…These challenges impact differently in each region and country as they are influenced by management failures, slaughter process, and poultry flock health (Buzdugan et al, 2020;De Souza, Granjeiro, and Procópio, 2019;Saraiva et al, 2021;Večerková, Voslářová, and Večerek, 2019). The latter, as it involves etiological agents, tends to be influenced by management and by geographic and climatic characteristics of each region and season of the year (Jaguezeski et al, 2020;Schulze Bernd et al, 2020;Souza et al, 2021).…”
