Development of strain-level shotgun metagenomics approaches to detect and characterize microbiological contaminants in the context of food safety
microbiological foodborne contaminants to the strain level and with achievement of a relatedness study (phylogeny), with a focus on the applicability of the method in order to be easily implemented in reference ...
Sensitivity of candling as routine method for the detection and recovery of ascaridoids in commercial fish fillets.
reference standard. The overall Se of candling was 31% (95% CI 23-41%) and NPV was 87% (95% CI 85-90%). The Se increased with higher numbers of larvae/100 g infected muscle. A low NPV was found for the belly ...
Application of a strain-level shotgun metagenomics approach on food samples: resolution of the source of a Salmonella food-borne outbreak
200 students and teachers. Following standard procedures, the Belgian National Reference Center for human salmonellosis and the National Reference Laboratory for Salmonella in food and feed used ...
