Modeling the Microbiological Shelf Life of Foods and Beverages

From about 1985 to 2015, the subject of predictive microbiology has become a mature area of study in and of itself. The ability to predict the growth of a bacterial species within a food matrix for a given set of intrinsic and environmental conditions offers many advantages and benefits…

Next generation of microbiological risk assessment: Potential of omics data for exposure assessment

In food safety and public health risk evaluations, microbiological exposure assessment plays a central role as it provides an estimation of both the likelihood and the level of the microbial hazard in a specified consumer portion of food and takes microbial behaviour into account. While until now mostly phenotypic…

Feed to fork risk assessment of mycotoxins under climate change influences – recent developments

This review undertakes a systematic approach to identify scientific studies that assess mycotoxin production in feed and cereals which may be influenced by weather variables or climate change scenarios. It also looks at human health risk assessments carried out in the past 20 years related to mycotoxins detected in…

Flow Cytometric and 16S Sequencing Methodologies for Monitoring the Physiological Status of the Microbiome in Powdered Infant Formula Production

The aim of this study was to develop appropriate protocols for flow cytometric (FCM) and 16S rDNA sequencing investigation of the microbiome in a powdered infant formula (PIF) production facility. Twenty swabs were collected from each of the three care zones of a PIF production facility and used for…

A data-driven approach for prioritising microbial and chemical hazards associated with dairy products using open-source databases

This study presents a data-driven approach for classifying food safety alerts related to chemical and microbial contaminants in dairy products using the Rapid Alert System for Food and Feed (RASFF) and the World Health Organization (WHO)’s Global Environmental Monitoring System (GEMS) food contaminants databases….

16S rRNA Based Profiling of Bacterial Communities Colonizing Bakery-Production Environments

Conventional culture-based techniques are largely inadequate in elucidating the microbiota contained in an environment, due to low recovery within a complex bacterial community. This limitation has been mitigated by the use of next-generation sequencing (NGS)-based approaches thereby facilitating the identification and classification of both culturable and uncultivable microorganisms. Amplicon…

Microbial Risk Ranking as “a web-based decision support system” tool [Conference Paper]

WHO estimates that more than 23 million people fall ill from eating contaminated food with bacteria, viruses, and parasitic protozoa in the European region every year, resulting in 4,654 deaths and more than 400,000 DALYs. Reducing these numbers has proven challenging because of the complex European food supply chain…
