Impact of thermal and high-pressure treatments on the microbiological quality and in vitro digestibility of black soldier fly (Hermetia illucens) larvae (2020)
Journal Article

Black soldier fly larvae (BSFL) are gaining importance in animal feeding due to their ability to upcycle low-value agroindustry by-products into high-protein biomass. The present study evaluated the nutritional composition of BSFL reared on brewer’s...

The Campylobacter jejuni type VI secretion system enhances the oxidative stress response and host colonization (2019)
Journal Article

The role of the Type VI secretion system (T6SS) in Campylobacter jejuni is poorly understood despite an increasing prevalence of the T6SS in recent C. jejuni isolates in humans and chickens. The T6SS is a contractile secretion machinery capable of de... Read More about The Campylobacter jejuni type VI secretion system enhances the oxidative stress response and host colonization.

Thermal and non-thermal processing technologies on intrinsic and extrinsic quality factors of tomato products: A review (2019)
Journal Article

Tomato and tomato-based products play a vital role in human diet due to the presence of bioactive compounds. The conventional heat treatment is designed as a current practice in tomato products industry to ensure food safety but it can lead to undesi...

The antimicrobial effect of a commercial mixture of natural antimicrobials against Escherichia coli O157:H7 (2019)
Journal Article

Ruminants are important reservoirs of E. coli O157:H7 and are considered as the major source of most foodborne outbreaks (e.g., 2017 outbreak in Germany, 2014 and 2016 outbreaks in United States, all linked to beef products). A promising strategy to... Read More about The antimicrobial effect of a commercial mixture of natural antimicrobials against Escherichia coli O157:H7.

Evaluation of the efficacy of multiple physical, biological and natural antimicrobial interventions for control of pathogenic Escherichia coli on beef (2018)
Journal Article

© 2018 Elsevier Ltd Antimicrobial effects of multiple physical, biological and natural interventions on pathogenic Escherichia coli in raw beef were assessed. A cocktail of E. coli strains was inoculated onto gamma-irradiated beef and enumerated imme...

The STARTEC decision support tool for better tradeoffs between food safety, quality, nutrition, and costs in production of advanced ready-to-eat foods (2017)
Journal Article

A prototype decision support IT-tool for the food industry was developed in the STARTEC project. Typical processes and decision steps were mapped using real life production scenarios of participating food companies manufacturing complex ready-to-eat...

The in vitro and ex vivo effect of Auranta 3001 in preventing Cryptosporidium hominis and Cryptosporidium parvum infection (2017)
Journal Article

Background: Cryptosporidium is a major cause of diarrhea worldwide in both humans and farm animals with no completely effective treatment available at present. In this study, we assessed the inhibitory effect of different concentrations of Auranta 30...

The in vitro effect of carvacrol, a food additive, on the pathogenicity of O157 and non-O157 Shiga-toxin producing Escherichia coli (2017)
Journal Article

© 2017 Elsevier Ltd Shiga toxin producing Escherichia coli (STEC) are important pathogens implicated in foodborne outbreaks and severe human infections. E. coli O157:H7 is the most common strain amongst STECs however non-O157 STECs have been connecte...
