The research was conducted at a federally inspected slaughterhouse located in the Southwest region of Goiás, between September and December 2024, totaling the analysis of 6,182 loads, corresponding to approximately 27.8 million birds with an average weight between 2.5 and 3.84 kg, an average age of 36 to 42 days, and up to 12 birds per cage. The variables studied included gender, lineage, density (kg/m²), rearing system, distance from the farm to the slaughterhouse, and weather conditions. The data were subjected to Principal Component Analysis (PCA) and Tukey's test. The results indicated that the variability of the broiler production system was predominantly explained by environmental variables, followed by factors associated with the incidence of muscle myopathies and, to a lesser extent, by productive and operational characteristics. The principal component analysis showed that the first components concentrated most of the total variance, highlighting the influence of climatic variables such as temperature, humidity, wind, and precipitation, in addition to MPP, WB, and SM myopathies. Complementarily, Tukey's test revealed significant differences in losses due to myopathies as a function of the month of the year, genetic lineage, and rearing system, with higher values observed in December, in the ROSS (A) lineage and in the Dark House system, while sex exerted a secondary influence. These results demonstrate the combined action of environmental, productive, and management factors in the occurrence of muscle myopathies in broilers.

The country’s relevance as a major producer and consumer of beef, pork and poultry intensifies the need for effective hygienic-sanitary control systems in a scenario marked by structural heterogeneity between regions, the presence of informal marketing segments and different levels of organization of inspection services (federal, state and municipal). In this context, Self-Control Programs (SCP) - which encompass Good Manufacturing Practices, Sanitation Standard Operating Procedures and Hazard Analysis and Critical Control Points - constitute a central tool for managing microbiological risks and achieving equivalence between inspection spheres, in line with the guidelines of the Brazilian Unified System of Agricultural Health Surveillance and related programs. Therefore, this study aimed to provide an overview of the microbiological quality of meat products in Brazil and to analyze the relationship between the stage of SCP implementation and official laboratory results in establishments under municipal inspection. A literature review was carried out using the Google Scholar database, covering articles published between 2019 and 2024, and an observational study was conducted in 18 establishments under the Municipal Inspection Service of Rio Verde, Goiás, relating the SCP implementation status to non-conformities and to microbiological and physicochemical results of meat products. The findings revealed strong regional heterogeneity, with higher non-compliance rates in meat sold at open-air markets and informal outlets in the North and Northeast regions, intermediate performance in the Center-West, and better indicators in the South and Southeast, where more structured production chains and greater presence of formal inspection predominate. It was also observed that establishments with absent or incipient SCPs concentrated most microbiological non-conformities, whereas those with more advanced implementation showed superior sanitary performance. Taken together, the results indicate that effective implementation of SCPs, associated with the strengthening of municipal inspection services and the expansion of the integration of local systems into national equivalence schemes, is strategic to reduce regional sanitary asymmetries, enhance public health protection and strengthen the competitiveness of Brazilian meat products in domestic and international markets.

EM SUPERFÍCIES COMPOSTAS POR POLIPROPILENO (PP) E POLIETILENO (PE) Autor(es): Zanol, Jaine Primeiro Orientador: Cappato, Leandro Pereira Abstract: Waterborne and Foodborne Diseases (WFD), resulting from the ingestion of pathogenic agents such as bacteria, viruses, parasites, toxins, or chemical substances, represent a significant public health concern. These diseases prevention is directly linked to the implementation of strict hygiene and sanitary controls in environments dedicated to food processing. Among the main bacterial agents associated with foodborne outbreaks worldwide, Salmonella spp. stands out, often linked to severe cases of foodborne infections.The sanitation stage serves as an essential barrier against the spread of WFDs in handling environments and is crucial for preventing the bacteria multiplication and dissemination throughout the production process. However, this stage requires a high volume of water, which underscores the need to develop methods that maintain sanitization effectiveness while optimizing water usage. Among the emerging techniques for environmental microbiological control, fogging, also known as aerosolization, has emerged as a promising alternative, especially due to its application method, which involves the dispersion of a fine sanitizing mist. This characteristic allows for homogeneous surface coverage and enables its use in different production environments, enhancing the overall effectiveness of the sanitation process. Given this context, the present study aims to evaluate the sanitizing efficacy of peracetic acid applied to polypropylene (PP) and polyethylene (PE) surfaces experimentally contaminated with pooled strains of Salmonella Typhimurium, Salmonella Enteritidis, and Salmonella Kentucky. Then, fogging and immersion techniques were employed, and the efficiency of the sanitization process was analyzed at different exposure times, along with the volume of water used in each method. The results demonstrated the effectiveness of both techniques evaluated, indicating that this is an emerging and applicable method for the decontamination of surfaces composed of polypropylene (PP) and polyethylene (PE).

Autor(es): Abrantes, Ruan Henrique Alves Primeiro Orientador: Oliveira, Daniel Emanuel Cabral de Primeiro Membro da Banca: Oliveira, Daniel Emanuel Cabral de Segundo Membro da Banca: Romani, Viviane Patrícia Terceiro Membro da Banca: Resende, Osvaldo Abstract: Knowing the physical, chemical and technological properties of plant products is extremely important. In the case of grains, as well as other agricultural products, its determination is even more important, as it is directly related to the storage, quality and efficiency of post-harvest processes. Thus, this work aims to determine the physical, chemical and technological properties of different chickpea cultivars. The grains were produced at the Federal Institute of Goiás - Campus Iporá and the analyses were conducted at the Laboratory of Post-Harvest of Plant Products of the Federal Institute of Goiano - Campus Rio Verde. The results were submitted to the analysis of variance and Scott-Knott mean test up to 5% probability using the statistical program Sisvar. It was observed that the GB 2112762173 cultivar stood out in the physical characteristics presenting high values of real and apparent specific mass, in addition to a relatively low porosity. Regarding chemical characteristics, the GB ALEPPO NEW 2168 cultivar appears to be the most proteinic, while the GB 20 056 A 217 had the lowest lipid index, and the GB 20006 was the richest in carbohydrates and energy value. In relation to grain and flour color, GB 05155 and GB 2119682178 cultivars were the lightest, GB 20146MT and GB 20006 the reddest, GB 2112762173 and GB CRISTALINO 2163 the most yellowish. The GB ZEUS cultivar had the best result in oil absorption, BRS TORO excelled in water solubility, and GB 200012164 proved to be better in water absorption; in terms of dimensions and projected area, GB 20056A2179 had the best numbers, while the GB 2112102169 excelled in roundness and sphericity Editor: Instituto Federal Goiano Tipo: Dissertação Thu, 20 Mar 2025 00:00:00 GMT https://repositorio.ifgoiano.edu.br/handle/prefix/5443 2025-03-20T00:00:00Z
