Background. Listeriosis is a serious foodborne infection. Outbreaks of listeriosis occur rarely, but have often proved difficult to solve. In June 2014, we detected and investigated outbreak in Denmark using patient interviews whole-genome sequencing (WGS). Methods. We performed WGS on Listeria monocytogenes isolates from patients available ready-to-eat foods compared them single-nucleotide polymorphism (SNP) analysis. Case had L. with ≤3 SNPs (the strain) isolated September 2013−December...
Reduction of Campylobacter on broiler meat is crucial for decreasing the number campylobacteriosis cases. A module (IceGun®) that sprays slurry ice carcasses has been developed to enhance chilling capacity in poultry slaughterhouses and may, addition, help reduce bacterial load. The present study investigated how affects load carcasses. Neck skin pool samples from IceGun® treated (n = 840) control were sampled a slaughterhouse under industrial working conditions September 2022 January 2023...
Intra-species restriction fragment length polymorphisms (RFLPs) of Yersinia enterocolitica were detected in assays with a cloned DNA from Legionella pneumophila that included the 16S and 23S rRNA genes. By use this method it was possible to identify different RFLP types within biogroups/serogroups which indistinguishable by other means. Thus 37 biogroup IV/serogroup O3 strains isolated worldwide pig carcasses, pork human patients, subdivided into five RFLP-types. Typing based on analysis...
Indiscriminate use of antimicrobials for the prevention and treatment bacterial infection in animals is a common practice Nigeria as other developing countries. These are purchased over counter without restrictions often administered form medicated feedstuffs. In Nigeria, like most countries, antimicrobial prescription data not routinely collected or reported at farm level, instead import used reporting consumption. Farmers can be useful sources on agents by class, animal species, production...
A total of 245 strains Listeria monocytogenes, representing 33 different electrophoretic types (ETs), were examined quantitatively for haemolytic activity. No significant difference was observed in the mean activity between ETs. Eighty four out 91 found to be virulent chick embryos. Strains belonging ET 2 and 4 less than other ETs (P = 0·0447). Furthermore, from clinical cases more 0·0002) foods (the MTD among 2·46 compared with 3·64 food isolates). The explanation this may that are prone...
A specific PCR assay was used to detect Salmonella in enriched broths of 48 natural samples minced pork and beef. By comparison with a routine culture method, the sensitivity method estimated be 92% specificity 99%. The 50% this study.
The European Food Safety Authority asked the Panel on Biological Hazards (BIOHAZ) to deliver a scientific opinion providing: (i) review of approaches used by BIOHAZ address requests from risk managers suggest establishment microbiological criteria; (ii) guidance required evidence, data and methods/tools necessary for considering development criteria pathogenic microorganisms indicator microorganisms; (iii) recommendations design (iv) guidelines requirements tasks assessors, compared...
Listeria monocytogenes is an ubiquitously occurring foodborne bacterial pathogen known to contaminate foods during the production processes. To assess presence and persistence of L. in Danish ready-to-eat (RTE) food companies response a awareness campaign, environment selected were sampled 2016 2020. Whole genome sequencing (WGS) was performed characterize isolates (n = 50, plus 35 obtained from routine surveillance 2016–2020), including investigation virulence, resistance genes. The number...
Abstract In a previous study spatially distributed hydrological model, based on the MIKE SHE code, was constructed and validated for 375 000 km 2 Senegal River basin in West Africa. The model using spatial data topography, soil types vegetation characteristics together with time‐series of precipitation from 112 stations basin. calibrated river discharge nine 11 years. Calibration validation results suggested that resolution input parts area not sufficient satisfactory evaluation modelling...
Campylobacter cross-contamination of Danish broiler flocks at slaughterhouses was investigated using data from two national surveillance components and ad-hoc sampling. The animal level (AL) food safety (FS) 2018 were compared. AL component contained results PCR on pools cloacal swabs 3,012 processed (S1-S2), while the FS regarded culture testing leg skins 999/3,012 flocks. monthly "apparent" (AP) "true" flock prevalence (TP) estimated. Agreement between measured in percentage weighted-Kappa...
