Pathogens-in-Foods (PIF): An open-access European database of occurrence data o...
Gonzales-Barron, Ursula; Faria, Ana Sofia; Thebault, Anne; Guillier, Laurent; Mendes, Lucas Ribeiro; Silva, Lucas Ribeiro; Messens, Winy; Kooh, PaulineThe collection of occurrence data of foodborne pathogens in foods faces the hindrances of dispersion of information, lack of standardisation and harmonisation, and ultimately, high expenditure in time and resources. The Pathogens-in-Foods (PIF) database was conceived as a solution to centralise published data on prevalence and concentration of pathogenic bacteria, viruses and parasites occurring in foods, obtai...
Controlling Listeria monocytogenes contamination in fresh goat milk cheeses: Dy...
Bonilla-Luque, Olga María; Possas, Arícia; Gonzales-Barron, Ursula; Cadavez, Vasco; Ezzaky, Youssef; Hussein, Abdelraheem; Valero, AntonioPredictive models applied for artisanal fresh goat cheeses are invaluable tools for rapid decision-making in quality and safety management. Listeria monocytogenes is a common foodborne pathogen associated with recent safety alerts in ready-to-eat (RTE) products in Andalucia. Managing artisanal production variables, such as storage conditions and final product features (pH or water activity [aw]) might be crucia...
Valorisation of olive oil by-products into pectic- and glucuronoxylo-oligosacch...
Cordeiro, Ana; Fernandes, Andreia; Ferreira, Andreia S.; Coelho, Elisabete; Coimbra, Manuel A.; Silvério, Sara C.; Cadavez, Vasco; Peres, António M.Olive pomace (OLP) and stones (OLS) are key by-products of olive oil production, rich in lignocellulose and pectin, making them viable substrates for prebiotic oligosaccharide (OS) production. This study evaluated the chemical composition of OLP and OLS powders (OLPp and OLSp) and their potential for OS production through one-step fermentation using recombinant Bacillus subtilis 3610. Both substrates had compar...
A Quantitative Risk Assessment Model for Listeria monocytogenes in Ready-to-Eat...
Guillier, Laurent; Gonzales-Barron, Ursula; Pouillot, Régis; Mota, Juliana De Oliveira; Allende, Ana; Kovacevic, Jovana; Guldimann, ClaudiaThis study introduces a farm-to-fork quantitative risk assessment (QRA) model for invasive listeriosis from ready-to-eat diced cantaloupe. The modular model comprises seven stages-preharvest (soil and irrigation contamination), harvest (cross-contamination and survival), pre-processing (brushing), processing (flume tank washing, dicing and equipment cross-contamination), lot testing, cold-chain transport and re...
Meta-analysis of antimicrobial activity of Allium, Ocimum, and Thymus spp. conf...
Bonilla-Luque, Olga María; Silva, Beatriz Nunes; Ezzaky, Youssef; Possas, Arícia; Achemchem, Fouad; Cadavez, Vasco; Gonzales-Barron, UrsulaBiopreservation strategies such as the use of Mediterranean plant extracts to ensure food safety are promising to deal with the emergence of antimicrobial resistances and the overreliance on food chemical additives. In the last few decades, antimicrobial susceptibility testing (AST) for evaluating the in vitro antibacterial potential of plant extracts against the most relevant foodborne pathogens has been widel...
A Critical Review of Risk Assessment Models for Listeria monocytogenes in Seafood
Gonzales-Barron, Ursula; Cadavez, Vasco; Mota, Juliana de Oliveira; Guillier, Laurent; Sanaa, MoezInvasive listeriosis, due to its severe nature in susceptible populations, has been the focus of many quantitative risk assessment (QRA) models aiming to provide a valuable guide in future risk management efforts. A review of the published QRA models of Listeria monocytogenes in seafood was performed, with the objective of appraising the effectiveness of the control strategies at different points along the food...
Microbiological and Physicochemical Profile of Traditionally Produced Chouriça ...
Faria, Ana Sofia; Bonilla-Luque, Olga María; Carvalho, Laís; Fernandes, Nathália; Prieto Lage, Miguel A.; Cadavez, Vasco; Gonzales-Barron, UrsulaThe physicochemical and microbiological properties of traditional Portuguese ready-to-eat dry fermented sausage chouriça de carne samples from 14 regional producers were analysed and subjected to multivariate analysis to determine the relationships between them and to evaluate how the quality and safety of these sausages is affected by these properties. Producer-mean values for physicochemical analyses were qui...
A Critical Review of Risk Assessment Models for Listeria monocytogenes in Meat ...
Gonzales-Barron, Ursula; Cadavez, Vasco; Mota, Juliana de Oliveira; Guillier, Laurent; Sanaa, MoezA review of the published quantitative risk assessment (QRA) models of L. monocytogenes in meat and meat products was performed, with the objective of appraising the intervention strategies deemed suitable for implementation along the food chain as well as their relative effectiveness. A systematic review retrieved 23 QRA models; most of them (87%) focused on ready-to-eat meat products and the majority (78%) al...
A Quantitative Risk Assessment Model for Listeria monocytogenes in Ready-to-Eat...
Gonzales-Barron, Ursula; Pouillot, Régis; Skjerdal, Taran; Carrasco, Elena; Teixeira, Paula; Stasiewicz, Matthew J.; Hasegawa, AkioThis study introduces a quantitative risk assessment (QRA) model aimed at evaluating the risk of invasive listeriosis linked to the consumption of ready-to-eat (RTE) smoked and gravad fish. The QRA model, based on published data, simulates the production process from fish harvest through to consumer intake, specifically focusing on smoked brine-injected, smoked dry-salted, and gravad fish. In a reference scenar...
Chemical profiles and bioactivities of polyphenolic extracts of Lavandula stoec...
Silva, Beatriz Nunes; Cadavez, Vasco; Caleja, Cristina; Pereira, Eliana; Calhelha, Ricardo C.; Molina, Adriana K.; Finimundy, Tiane C.; Kostić, MarinaThis study assessed the chemical profiles and bioactivities of the infusions, decoctions and hydroethanolic extracts of tarragon, basil and French lavender. The extracts were chemically characterised (HPLC-DAD-ESI/MS) and their bioactivities were evaluated in vitro. All extracts revealed antimicrobial, antifungal and antioxidant properties. French lavender extracts showed higher total phenolic content, regardle...
