Background: Campylobacter jejuni is the leading cause of human bacterial gastroenteritis worldwide. However, systemic infection with C. jejuni is uncommon, and osteomyelitis caused by C.

- Several proficiency testing (PT) and external quality assessment (EQA) schemes exist for evaluating laboratories' abilities to detect enteropathogenic bacteria, but they mainly focus on specific sectors like public health, food safety, or animal health.
- This study aims to assess the cross-sectoral detection capabilities of European laboratories for foodborne pathogens and propose recommendations for enhancing cross-sectoral PTs and EQAs in a One Health context.
- The results showed that while all participating laboratories recognized certain pathogens, many faced challenges with false negatives, especially with lower concentrations of target organisms, due to factors like smaller sample sizes and lack of enrichment methods.
The prevalence of verocytotoxin producing Escherichia coli (VTEC), E. coli O157, and VTEC O157 in 474 swab samples from Danish beef carcasses was determined. The presence of E.

The source of the infection was an organic fermented beef sausage. The source was discovered by using credit card information to obtain and compare customer transaction records from the computer systems of supermarkets.

MICs were determined by the agar dilution procedure in the testing range of 3 to 60 microg/ml metronidazole. The MICs showed a bimodal distribution with a significant proportion of metronidazole-resistant isolates among C.

The food samples consisted of raw chicken meat and other raw poultry meat of domestic or imported origin. The highest levels of resistance among C.

The study included a total of 149 Danish eae-positive VTEC O157 isolates (63 of bovine origin and 86 from human clinical cases) isolated between 1987 and 2001. All were analysed by vtx-PCR-RFLP and phage typing.
