Lack of evidence so far for Noroviruses in food samples collected on cruise ships sailing the Mediterranean waters
No full textClosed living spaces like cruise ship settings create an environment in which enteric viruses including Noroviruses (NoVs) can easily spread and outbreaks readily occur. The contribution of sources other than common confirmed vehicles to foodborne illness in cruise ships was investigated. None of the 189 collected samples (including meat, fish, buffet meals, fruits, vegetables etc.) tested by real-time RT-PCR (ISO/TS 15216-2:2013) reveled NoVs genome. Naturally contaminated food items other than shellfish have been demonstrated to be cause of NoVs infection thus, our results could neither indicate nor exclude food items as possible vehicle of infection. Reducing risk factors associated with NoVs outbreaks (contaminated raw ingredients, cross contamination, infected food handlers, inadequate temperature controls, heat treatments) is always strongly recommended

No full textA cross-sectional serological survey was conducted in order to evaluate, irrespective of abortion, the Toxoplasma gondii infection in pastured sheep from the Campania region of southern Italy. A geographical information system was used in order to uniformly sample the ovine farms (n = 117) throughout the entire region. Blood and milk samples were collected from 10 adult sheeps (>18 months) on each farm (total number = 1170 sheeps). Serum samples were tested for the presence of IgG antibodies to T. gondii using a commercial indirect fluorescent antibody test. For each farm, the 10 milk samples collected were pooled in order to obtain a single milk sample per farm (total number = 117 milk samples). The 77.8% (91/117) of the farms and the 28.5% (333/11,170) of the sheep resulted positive by serology. In addition, the presence of T. gondii DNA was detected by PCR in 4 milk samples out of the 117 examined (3.4%)

Antimicrobial susceptibility testing for salmonella serovars isolated from food samples: Five-year monitoring (2015–2019)
No full textThe continuous collection and analysis of updated data on the antimicrobic resistance among bacterial strains represent the essential core for the surveillance of this problem. The present work aimed to investigate the occurrence of antimicrobial resistance among Salmonella serovars isolated in foods in 2015–2019. A total of 178 Salmonella strains belonging to 39 serovars were tested against 10 antimicrobials. High proportions of Salmonella isolates were resistant to tetracycline (n = 53.9%), ciprofloxacin (n = 47.2%), ampicillin (n = 44.4%), nalidixic acid (n = 42.7%), and trimethoprim-sulfamethoxazole (n = 38.8%). Different resistance rates were recorded among the different serotypes of Salmonella, and S. Infantis, exhibited the highest resistance to antibiotics. A high percentage of strains isolated from poultry, pork, and bovine were resistant to at least one or two antimicrobials. Resistant and multidrug-resistant (MDR) strains were also recorded among the isolates from molluscan shellfish; however, the occurrence of resistant Salmonella strains isolated from this source was significantly lower compared with those reported for poultry, pork, and bovine. The high levels of resistance reported in the present study indicate a potential public health risk. Consequently, additional hygiene and antibiotic stewardship practices should be considered for the food industry to prevent the prevalence of Salmonella in foods
