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...
Molecular tracking of Salmonella spp. in chicken meat chain: from slaughterhous...
Dias, Mariane Rezende; Cavicchioli, Valéria Quintana; Camargo, Anderson Carlos; Lanna, Frederico Germano Piscitelli AlvarengaDue to the importance of Salmonella spp. in poultry products, this study aimed to track its main contamination routes since slaughtering reception to processing of chicken end cuts. Samples from different steps of slaughtering and processing (n = 277) were collected from two chicken slaughterhouses (Sl1 and Sl2) located in Minas Gerais state, Brazil, and subjected to Salmonella spp. detection. The obtained isol...
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...
Rastreamento molecular de Salmonella spp. e contaminação microbiológica na linh...
Dias, Mariane RezendeA obtenção de alimentos com padrões de inocuidade e qualidade microbiológica é essencial, uma vez que alimentos contaminados estão frequentemente envolvidos em casos de enfermidades de origem alimentar. Nesse contexto, destaca-se a importância da pesquisa de micro-organismos indicadores de higiene e também de patógenos nas diferentes etapas da linha de abate e processamento. A pesquisa de Salmonella spp. é fund...
