Combination of organic acids and low-dose gamma irradiation as antimicrobial treatment to inactivate Shiga toxin-producing Escherichia coli inoculated in beef trimmings: Lack of benefits in relation to single treatments
Cap, Mariana; Cingolani, Celeste; Lires, Carla; Mozgovoj, Marina Valeria; Soteras, Trinidad; Sucari, Adriana; Gentiluomo, Jimena; Descalzo, Adriana Maria; Grigioni, Gabriela Maria; Signorini, Marcelo; Horak, Celina; Vaudagna, Sergio Ramon; Leotta, Gerardo (Plos ONE, 2020-03-26)The aim of this study was to assess the efficacy of lactic acid (LA), caprylic acid (CA), high- (HDI) and low- (LDI) dose gamma irradiation and LDI combined with LA or CA on the inactivation of a pool of Shiga toxin-producing ... -
Comparison of six commercial systems for the detection of non-O157 STEC in meat and vegetables
Costa, Magdalena; Sucari, Adriana; Epszteyn, Sergio; Oteiza, Juan Martín; Gentiluomo, Jimena; Melamed, Celia; Figueroa, Yamila; Mingorance, Santiago Emmanuel; Grisaro, Agustina; Spioussas, Silvia; Buffoni Almeida, Mariana; Caruso, Mailen; Pontoni, Andrés; Signorini, Marcelo; Leotta, Gerardo Anibal (Elsevier, 2019-12)Shiga toxin-producing Escherichia coli (STEC) are important pathogens transmitted by food that may cause severe illness in human beings. Thus, systems for STEC detection in food should have increasingly higher sensitivity ... -

Costa, Magdalena; Pracca, Gabriela; Sucari, Adriana; Galli, Lucía; Ibargoyen, José; Gentiluomo, Jimena; Brusa, Victoria; Martinez Zugazua, Matías; Figueroa, Yamila; Londero, Alejandra; Rogé, Ariel Diego; Silva, Hernán; Ploeg, Claudia A. Van Der; Signorini, Marcelo; Oteiza, Juan Martín; Leotta, Gerardo Anibal (Elsevier, 2020-03)The slaughter process plays an important role in animal welfare, meat quality, safety and public health through the meat production chain. In this study, we performed a three-stage evaluation: I) comprehensive evaluation, ... -
Identification of the gamma irradiation dose applied to ground beef that reduces Shiga toxin producing Escherichia coli but has no impact on consumer acceptance
Cap, Mariana; Lires, Carla M.L.; Cingolani, Celeste; Mozgovoj, Marina Valeria; Soteras, Trinidad; Gentiluomo, Jimena; Príncipe, F.; Sucari, Adriana; Horak, Celina I.; Signorini Porchiett, Marcelo Lisandro; Vaudagna, Sergio Ramon; Leotta, Gerardo Anibal (Elsevier, 2020-11-18)The aims of the present study were: a) to estimate the minimal dose of gamma irradiation required to reduce 5 log CFU/g of native O157 and non-O157 Shiga toxin-producing Escherichia coli population in ground beef samples ...
