“…From the studies reviewed, the foods implicated in foodborne outbreaks are: fish and seafood [70],[88],[89],[90],[94],[95],[96],[113], liver pâtè [24]–[30], chicken products [33],[36], meat and meat products [37],[51],[52],[68],[76], ice cream [71], raw milk [31], rice dishes [15],[16], pasta and pasta salad [18],[19], peanuts [72], flour [61],[62], cold sandwiches [83], fruit juices [35] and fresh produce [49],[50],[53]–[60],[67],[69],[73],[74],[75],[84],[93],[101],[102],[103],[114]. Fresh produce have attracted great attention during the last 20 years, and it seems that there is some weakness of available international networks, as detection and real-time data show [130].…”

“…Because consumption of pasteurized milk is common and outbreaks have the potential to become large, public health interventions such as consumer advisories or closure of the dairy must be implemented quickly to prevent additional cases if epidemiological or laboratory evidence implicates pasteurized milk as the outbreak source [92]. In addition, Y. enterocolitica serogroup O:8 was isolated from 24 fecal specimens of 21 patients and 3 kitchen staff in an outbreak in Japan; fresh vegetable salad was confirmed as the incrimination food of this outbreak [93].…”

Foodborne pathogens are causing a great number of diseases with significant effects on human health and economy. The characteristics of the most common pathogenic bacteria ( Bacillus cereus , Campylobacter jejuni , Clostridium botulinum , Clostridium perfringens , Cronobacter sakazakii , Esherichia coli , Listeria monocytogenes , Salmonella spp., Shigella spp., Staphylococccus aureus , Vibrio spp. and Yersinia enterocolitica ), viruses (Hepatitis A and Noroviruses) and parasites ( Cyclospora cayetanensis , Toxoplasma gondii and Trichinella spiralis ), together with some important outbreaks, are reviewed. Food safety management systems based on to classical hazard-based approach has been proved to be inefficient, and risk-based food safety approach is now suggested from leading researchers and organizations. In this context, a food safety management system should be designed in a way to estimate the risks to human health from food consumption and to identify, select and implement mitigation strategies in order to control and reduce these risks. In addition, the application of suitable food safety education programs for all involved people in the production and consumption of foods is suggested.

“…The situation is the opposite for vegetables and milk products. Both food categories were not identified as risk factors in the meta-analysis (see Appendix 2), although several outbreaks have been associated to these food products, especially for vegetables, in recent years (Espenhain et al, 2019;Konishi et al, 2016;MacDonald et al, 2012).…”

“…Microbiological and epidemiological investigations make it possible to identify outbreaks and to trace back the food at the origin of the human cases (Espenhain et al, 2019). Although outbreaks are identified (Konishi et al, 2016;MacDonald et al, 2012), a majority of yersiniosis cases caused by Y. enterocolitica are not associated with any known outbreak (Marimon et al, 2017) and are classified as sporadic cases. The question of specific environmental or food exposures and their respective weight for these sporadic cases arise.…”

Yersinia enterocolotica is an important causative agent of diarrheal illness. A systematic review and meta-analysis of case-control studies were performed to determine the main risk factors associated with sporadic Y. enterocolitica infections. Suitable scientific articles published between 1987 and 2017 were identified through a systematic literature search and subject to methodological quality assessment. From each study, odds ratios (OR) were extracted or calculated, as well as study characteristics such as population type, design, type of model used and risk factor categorization. Mixed-effects meta-analytical models were adjusted by population type to appropriate data partitions. From 807 identified references, the quality assessment stage was passed by 14 casecontrol studies focusing on sporadic Y. enterocolitica infections which provided 165 ORs for meta-analysis. All studies considered Y. enterocolitica as the cause of sporadic infections and are mainly located in Europe. The meta-analysis identified host-specifics factors, animal and food exposures as significant risk factors. The meta-analysis confirms the predominant role of the pig reservoir. The occupational contact with pigs and the consumption of pork meat are significantly associated with sporadic Y. enterocolitica infections occurrence. The consumption of raw or undercooked pork meat is also a very important risk factor. Untreated drinking water was also identified as risk factor. Further studies with other enteropathogenic Yersinia species, especially Y. pseudotuberculosis, and/or from other continents would help to refine conclusions of the meta-analysis of the risk factors of yersiniosis.

“…The diagnostic methods for pathogenic Yersinia are mainly based on conventional isolation and identification procedures [7,13]; however, these methods are time-consuming and laborious. Recently, some PCR methods have been developed to detect Y. enterocolitica and Y. pseudotuberculosis, allowing rapid diagnosis [6,20].…”
