“…Barco et al. () reviewed the relationship between indicator bacteria ( E. coli and Enterobacteriaceae) counts and visual faecal contamination of cattle and beef carcasses. It was concluded that slaughterhouse characteristics influence bacterial load of beef carcasses, although it is difficult to determine which factors (i.e.…”

The European Food Safety Authority asked the Panel on Biological Hazards (BIOHAZ) to deliver a scientific opinion providing: (i) a review of the approaches used by the BIOHAZ Panel to address requests from risk managers to suggest the establishment of microbiological criteria; (ii) guidance on the required scientific evidence, data and methods/tools necessary for considering the development of microbiological criteria for pathogenic microorganisms and indicator microorganisms; (iii) recommendations on methods/tools to design microbiological criteria and (iv) guidelines for the requirements and tasks of risk assessors, compared to risk managers, in relation to microbiological criteria. This document provides guidance on approaches when: (i) a quantitative microbial risk assessment (QMRA) is available, (ii) prevalence and concentration data are available, but not a QMRA model, and (iii) neither a QMRA nor prevalence and/or concentration data are available. The role of risk assessors should be focused on assessing the impact of different microbiological criteria on public health and on product compliance. It is the task of the risk managers to: (1) formulate unambiguous questions, preferably in consultation with risk assessors, (2) decide on the establishment of a microbiological criterion, or target in primary production sectors, and to formulate the specific intended purpose for using such criteria, (3) consider the uncertainties in impact assessments on public health and on product compliance and (4) decide the point in the food chain where the microbiological criteria are intended to be applied and decide on the actions which should be taken in case of noncompliance. It is the task of the risk assessors to support risk managers to ensure that questions are formulated in a way that a precise answer can be given, if sufficient information is available, and to ensure clear and unambiguous answers, including the assessment of uncertainties, based on available scientific evidence.

“…The food industry routinely monitors Enterobacteriaceae and/or the coliforms, a subgroup of Enterobacteriaceae , as indicator organism to assess good manufacturing practice and sanitary conditions employed during food processing (Kornacki, ; Buchanan and Oni, ; Barco et al ., ). The ability of coliforms to ferment lactose is used as a marker to identify and enumerate them during conventional culturing; however, some non‐coliforms such as Aeromonas spp., can ferment lactose and produce false results (Baylis et al ., ).…”

Summary E nterobacteriaceae family comprised pathogens and commensals and has a significant impact on food safety and public health. E nterobacteriaceae is often enumerated and presumptively identified on chromogenic media, such as CHROMagarTM Orientation medium based on colony profile; however, classification is highly arbitrary, and some could not be differentiated due to similar chromogen production. Here, we investigated the ability of the laser optical sensor, BARDOT (bacterial rapid detection using optical scattering technology) for rapid screening and differentiation of colonies of the major bacterial genera from E nterobacteriaceae on CHROMagarTM Orientation. A total of 36 strains representing 12 genera and 15 species were used to generate colony scatter image library that comprised 1683 scatter images. This library was used to differentiate mixed cultures of E nterobacteriaceae family – K lebsiella pneumoniae, E nterobacter spp., C itrobacter freundii and S erratia marcescens (KECS group); P roteus mirabilis, M organella morganii and P rovidencia rettgeri (PMP group); and non‐E nterobacteriaceae family: P seudomonas aeruginosa, A cinetobacter spp. and S taphylococcus aureus (PAS group) – and data show high accuracy (83–100%) for intra‐group classification of colonies in 10–22 h or even before visible production of chromogens. BARDOT successfully differentiated the major genera, including the ones that do not produce visually distinguishable chromogens on CHROMagarTM Orientation, providing a label‐free, real‐time on‐plate colony screening tool for E nterobacteriaceae.

“…Para manter a qualidade microbiológica da carne deve-se aplicar medidas de controle higiênicosanitárias desde as linhas de abate até a comercialização do produto final, uma vez que os alimentos de origem animal são os mais frequentemente envolvidos em surtos de Doenças Transmitidas por Alimentos (DTA) (Germano, 2003;Silva et al, 2014;Barco et al, 2015). Desta forma, torna-se imprescindível o conhecimento, controle e fiscalização da qualidade dos alimentos, sendo que um dos mais importantes focos de fiscalização devem ser os manipuladores envolvidos nas atividades de produção da carne, pois eles representam uma das principais formas de contaminação desse tipo de alimento (Souza, 2005;Oliveira et al, 2008;Pinto, 2008).…”
