- Incidence of Listeria spp. in domestic refrigerators in PortugalPublication . Azevedo, Inês; Regalo, Mafalda; Mena, Cristina; Almeida, Gonçalo; Carneiro, Luísa; Teixeira, Paula; Hogg, Tim; Gibbs, Paul A.The main objectives of this study were to determine the incidence of Listeria spp. in Portuguese domestic refrigerators and to evaluate some of the hygienic practices in the domestic environment that might contribute to the persistence of the organisms. It was found that L. monocytogenes was present in 3 domestic refrigerators of the 86 investigated. L. grayi and L. innocua were also isolated from 4 and 1 refrigerators, respectively. Overall, the information obtained from our survey demonstrates the need for consumer education in Portugal regarding safe food handling practices. For the refrigerators investigated, ≈71% were operating at a temperature higher than 6.1ºC, 87% were cleaned only monthly or less frequently, and only 8% were cleaned with appropriate proprietary cleaning products available in supermarkets.
- Food safety aspects concerning traditional foodsPublication . Belc, Nastasia; Duţă, Denisa Eglantina; Iorga, Enuţa; Mohan, Gabriela; Moşoiu, Claudia Elena; Vasile, Adrian; Sanmartin, Angel Martinez; Torres, Maria Antonia Pedrero; Martinez, David Quintin; Amaro, Ana L.; Teixeira, Paula; Cardoso, Eduardo L.; Pintado, M. E.; Ferreira, Vânia; Magalhães, Rui; Almeida, GonçaloA significant challenge for traditional food production is to improve its competitiveness by identifying innovations that guarantee the safety of the products, while at the same time meeting general consumer demands and specific consumer expectations towards traditional food (European Research on Traditional Food, EC, DG_Research, 2007). Therefore, there is a real need to study traditional foods in order to preserve important elements of European culture and, if possible, enrich and improve the diet across the whole continent. The following chapter will cover aspects related with the safety aspects of the traditional products including legislation, the hazards coming from raw materials as well as hazards from processing. Some technological solutions for making traditional foods safer in longer time will be presented. Even it is compulsory to follow the authentic recipe and technology; some small innovation would be necessary, for example, in packaging for better preservation of the traditional foods in order to meet consumer’s demands in having larger quantities of traditional foods. Technological innovations must be implemented in the companies always maintaining the traditional methodologies but assuring food safety and increasing shelf life of traditional foods.
- Food Safety in the domestic environment: kitchen hygienePublication . Noronha, Fátima; Silva, Susana Aragão; Mena, Cristina; Almeida, Gonçalo; Hogg, Tim; Gibbs, Paul; Teixeira, PaulaFoodbome diseases are widely accepted as one of the major public health concerns for all cOlUltries. According to the results of various studies, the domestic sector needs to be a key element in the reduction of foodbome illness as a significant proportion of these diseasescases arises from poor food handling and hygiene practices in the domestic envirornnent. The objective of this preliminary study was to obtain an indication of the level of hygiene of Portuguese kitchens. 10 domestic kitchens were characterized based on the presence of Escherichia coli, Staphylococcus aureus and Enterobacteriaceae in 16 different sampling points and ofListeria sp. in refrigerators and on the administration of a small questionnaire to the person responsible for the house cleaning and cooking about food safety and hygiene practices. Although based on a small number of homes, this study demonstrated that various points in the kitchen harbourharbor pathogenic organisms, thus being a possible source of food poisoning, for example through cross-contamination.
