Analysis of scenarios to reduce the probability of acquiring hemolytic uremic syndrome associated with beef consumption
Costa, Magdalena; Brusa, Victoria; Padola, Nora Lía; Etcheverría, Analía Inés; Sampedro, Fernando; Fernandez, Pablo S.; Leotta, Gerardo Anibal; Signorini Porchiett, Marcelo Lisandro (Sage Publications, 2021)The objective of this study was to develop a quantitative microbial risk assessment (QMRA) model to evaluate potential risk mitigation strategies to reduce the probability of acquiring hemolytic uremic syndrome (HUS) ... -
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 ... -
Comprehensive evaluation and implementation of improvement actions in bovine abattoirs to reduce pathogens exposure
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, ... -
Comprehensive evaluation of abattoirs with no Hazard Analysis Critical Control Point plan in Tucumán, Argentina = Evaluación integral de frigoríficos sin un plan de análisis de peligros y puntos críticos de control en Tucumán, Argentina
Pérez Terrazzino, Gabriela; Costa, Magdalena; López Campo, Alejandro; Saade, Carolina; Moreno Mochi, María Paula; Signorini Porchiett, Marcelo Lisandro; Roge, Ariel; Van Der Ploeg, Claudia; Leotta, Gerardo; Jure, María Ángela (Elsevier, 2023-02-25)This work focused on the comprehensive study of two provincial transit abattoirs in Tucumán, Argentina, with no Hazard Analysis Critical Control Point (HACCP) plan. Visits (n = 20) were conducted between 2016 and 2018 ... -
Evaluation of decontamination efficacy of commonly used antimicrobial interventions for beef carcasses against Shiga toxin-producing Escherichia coli
Signorini, Marcelo; Costa, Magdalena; Teitelbaum, David; Restovich, Viviana; Brasesco, Hebe; García, Diego; Superno, Valeria; Petroli, Sandra; Bruzzone, Mariana; Arduini, Victor; Vanzini, Mónica; Sucari, Adriana; Suberbie, Germán; Turina, Maricel; Rodriguez, Hector Ricardo; Leotta, Gerardo A. (2018-08)In Argentina, Shiga toxin producing Escherichia coli (STEC) serogroups O157, O26, O103, O111, O145 and O121 are adulterant in ground beef. In other countries, the zero-tolerance approach to all STEC is implemented for ... -
Isolation and characterization of non-O157 Shiga toxin-producing Escherichia coli from beef carcasses, cuts and trimmings of abattoirs in Argentina
Brusa, Victoria; Restovich, Viviana; Galli, Lucía; Teitelbaum, David; Signorini, Marcelo; Brasesco, Hebe; Londero, Alejandra; García, Diego; Padola, Nora Lía; Superno, Valeria; Sanz, Marcelo; Petroli, Sandra; Costa, Magdalena; Bruzzone, Mariana; Sucari, Adriana; Ferreghini, Marcela; Linares, Luciano; Suberbie, Germán; Rodriguez, Hector Ricardo; Leotta, Gerardo Anibal (2017-08-22)Several foods contaminated with Shiga toxin-producing Escherichia coli (STEC) are associated with human diseases. Some countries have established microbiological criteria for non-O157 STEC, thus, the absence of serogroups ... -
Prioritization of vegetable-borne biological hazards in Argentina using a multicriteria decision analysis tool
Brusa, Victoria; Costa, Magdalena; Oteiza, Juan Martín; Galli, Lucía; Barril, Patricia Angélica; Leotta, Gerardo Anibal; Signorini Porchiett, Marcelo Lisandro (SAGE Publications, 2023-06)Vegetables, especially those eaten raw, have been implicated in several foodborne disease outbreaks. Since multiple vegetable matrices and hazards are involved, risk managers have to prioritize those with the greatest ... -
