de Oliveira Ventura, Nayla Kellen; Costa, Letícia Roberta Martins [UNESP]; da Cunha Dias, Sthéfany [UNESP]; Nascimento, Yago Fernandes [UNESP]Made available in DSpace on 2022-04-28T19:29:53Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01; This study aimed to evaluate the adoption of good manufacturing practices and physico-chemical (pH and temperature) and microbiological parameters (presence of Salmonella spp.) of ground beef sold in butcher shops in Uberlândia, MG. Forty establishments from five regions of the city (eight per region) w...
Qualidade microbiológica de carne bovina moída comercializada em supermercados ...
Fenelon, Ana Carolina Guimarães; Andrade, Patrícia Lopes; Raghiante, Fernanda; Carrijo, Kênia de Fátima; Cossi, Marcus Vinícius CoutinhoBeef is the most consumed, present in the daily meals of Brazilian ground beef provides the preparation of various homemade meat products. Due to its physical and chemical characteristics, meat is a favorable medium for the development of microorganisms, and the processing of this food increases the possibilities of contamination and contact surface. The objective of the present work was to evaluate the microbi...
Microbiological testing for the proper assessment of the hygiene status of beef...
Camargo, Anderson Carlos; Cossi, Marcus Vinícius Coutinho; Silva, Wladimir Padilha da; Bersot, Luciano dos Santos; Landgraf, Mariza; Baranyi, JózsefMicrobiological testing is an important quality management tool in the food industry. In this study, the hygiene status of beef carcasses sampled in eight Brazilian slaughterhouses was assessed by enumeration of different hygiene indicator microorganisms, and a model to establish potential associations among these counts was proposed. The carcasses (n = 464) were surface sampled at four slaughtering steps (step...
Low occurrence of Salmonella in the beef processing chain from Minas Gerais sta...
Cossi, Marcus Vinícius Coutinho; Burin, Raquel Cristina Konrad; Camargo, Anderson Carlos; Dias, Mariane RezendeThe present study aimed to track possible contamination sources of Salmonella spp. during bovine slaughtering. Three slaughterhouses located in Minas Gerais state, Brazil were selected and 836 samples were obtained by surface swabbing of 209 bovine carcasses at four steps of slaughtering: I) after bleeding (from the hide), II) after skinning, III) after evisceration, and IV) after end washing (performed with co...
Comparison of destructive and nondestructive sampling techniques of retail chic...
Cossi, Marcus Vinícius Coutinho; Almeida, Michelle Vieira de; Dias, Mariane Rezende; Pinto, Paulo Sérgio de Arruda; Nero, Luís AugustoThe type of sampling technique used to obtain food samples is fundamental to the success of microbiological analysis. Destructive and nondestructive techniques, such as tissue excision and rinsing, respectively, are widely employed in obtaining samples from chicken carcasses. In this study, four sampling techniques used for chicken carcasses were compared to evaluate their performances in the enumeration of hyg...
Destructive and nondestructive procedures to obtain chicken carcass samples for...
Cossi, Marcus Vinícius Coutinho; Almeida, Michelle Vieira de; Dias, Mariane Rezende; Pinto, Paulo Sérgio de Arruda; Nero, Luís AugustoDestructive and nondestructive sampling procedures were compared for Escherichia coli and Salmonella spp. detection in 60 fresh chicken carcasses, which were submitted to the following sampling procedures: rinsing, skin swabbing, tissue excision, and skin excision; the proximity or not to the cloacae region was also considered. The obtained results were compared to identify significant differences (p<0.05). For...
Glucuronidase activity of escherichia coli isolated from chicken carcasses
Perin, Luana Martins; Yamazi, Anderson Keizo; Moraes, Paula Mendonça; Cossi, Marcus Vinícius Coutinho; Pinto, Paulo Sérgio de Arruda; Nero, Luís AugustoTo identify Escherichia coli through the production of -D-glucuronidase (GUD), 622 suspect cultures were isolated from chicken carcasses and plated in PetrifilmTM EC. Of these cultures, only 44 (7.1%) failed to produce GUD. This result indicates the usefulness of GUD production for estimating E. coli populations in chicken.
Avaliação de métodos de obtenção de unidades analíticas de carcaças de frango r...
Cossi, Marcus Vinícius CoutinhoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; The growing evolution of chicken meat production in Brazil determines the need of adequacy of several international markets, which demands hygienic quality and microbiological safety. Concerning this, the microbiological monitoring is a determinant factor for assure quality and safety of the avian food products, being the sampling procedure a key step...
Rastreamento e caracterização de Salmonella spp. em indústrias de processamento...
Cossi, Marcus Vinícius CoutinhoCoordenação de Aperfeiçoamento de Pessoal de Nível Superior; As Salmonella spp is still one of the most important foodborne pathogen related to public health, the aim of this study was to identify the contamination routs in beef chain production, through the identification of the pathogen in critical points of contamination on slaughterhouses and butcher shops. 3 slaughterhouses located in Minas Gerais state, B...
