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.
Introduction: Smaller scale, alternative, chicken production systems are gaining popularity globally. However, this brings public health and market confidence concerns, especially where there are no established standards of production. The aim of this study was to carry out a microbiological analysis of chicken carcasses from the commercial, backyard and semi-backyard production systems, slaughtered in the same slaughterhouse. Methodology: Samples of 102 chicken carcasses were taken in two steps of the slaughter (A: after bleeding; and B: after chiller tank) and were subjected to aerobic mesophilic, coliforms at 35 °C and coliforms at 45 °C counts, and Salmonella spp. detection. Salmonella spp. isolates were subjected to antimicrobial resistance analysis. Results: At slaughter step A, carcasses from the backyard system had less contamination than carcasses from the commercial system, with a difference of 0.7 log10 CFU/mL. Salmonella was identified in carcasses of all production systems and in both slaughter steps. Nine chicken carcasses were positive for Salmonella and no significant difference was observed in the occurrence of Salmonella amongst the carcasses from different production systems. Two Salmonella isolates, that presented the highest resistance profiles (one isolate was resistant to eight and the other to six out of ten tested antibiotics), were identified on carcasses from the semi-backyard system. Conclusions: Carcasses from the backyard system had a lower microbial count at the initial step of the slaughter process than the commercial production system. In addition, greater resistance to antimicrobials was observed in Salmonella isolates from semi-backyard system.
The aim of this study was to evaluate the influence of different periods of pre-slaughter fasting (F1: 2 to 24 hours and F2: 48 to 72 hours) on the counts of hygiene indicator microorganisms and the presence of Salmonella spp. in carcasses of bullfrogs. Two different stages of the slaughter process were analyzed: after bleeding (A) and after the final carcasses cleaning (B). Samples from each fasting period were analyzed to count hygiene indicator microorganisms (n=30) and Salmonella spp. (n=140). For aerobic mesophilic microorganisms, the variation in fasting periods caused a reduction of 0.69 log10 CFU / g (P<0.05) in F2 when compared to F1 at point B of the slaughter. Coliforms at 35º C and Escherichia coli showed no differences (P >0.05) between the fasting analyzed periods. Considering the presence of E. coli, it was observed that F2 resulted in a reduction of 30% (P<0.05) positivity on point B. For Salmonella spp., the results showed that F2 contributed to an 11.5% reduction in the presence of this bacteria at point B. (P<0.05). Therefore, it is concluded that 48 to 72 hours of pre-slaughter fasting resulted in a positive impact on the microbiological quality of bullfrog carcasses.
Este estudo teve como objetivo avaliar a adoção das boas práticas de fabricação e parâmetros físico-químicos (pH e temperatura) e microbiológico (presença de Salmonella spp.) da carne moída bovina comercializada em açougues de Uberlândia, MG. Foram analisados 40 estabelecimentos das cinco regiões do município (oito por região), sendo as boas práticas de fabricação avaliada por meio de um checklist (A. Edificações e Instalações; B. Equipamentos, móveis e utensílios; e C. Manipuladores). Para as análises físico-químicas e microbiológica foram coletadas 200g de carne moída bovina. Os estabelecimentos apresentaram 36,5% de inconformidade quanto à adoção das boas práticas de fabricação, sendo a área externa com focos de insalubridade e a lavagem das mãos os principais problemas observados. Em relação ás análises físico-químicas, identificou-se 75% de inconformidade dentre os açougues avaliados, sendo constatada também a presença de Salmonella spp. em amostras de carne de dois deles (5%). Conclui-se que existem falhas na adoção de boas práticas de fabricação e qualidade da carne analisada, e adequações são necessárias para a comercialização de alimentos seguros ao consumidor.
