“…In traditional food microbiological analysis methods, it must be considered that Shigella is sensitive to environmental conditions and can die quickly, particularly when exposed to direct sunlight or food processing conditions (dehydration), intrinsic characteristics of the food (composition, pH and saline concentration), in addition to the natural microbiota that competes for nutrients, affect and complicate the isolation of the pathogen from food, so that the analysis may require enrichment methods for better detection when it is in low numbers or weakened physiological state (Lampel, 2009;Anselmo et al, 2020).…”

“…Any colony that ferments glucose in these media without producing gas, does not use lactose, does not produce H 2 S, is immobile, does not decarboxylate and deaminates lysine, does not deaminates tryptophan, in addition to not having urease or oxidase production is suspected Shigella spp. (Prats and Mirelis, 1998;León-Ramirez, 2002;Mindy et al, 2004;Álvarez et al, 2008;Lampel, 2009;Wallace and Andrew, 2018;Anselmo et al, 2020). The biochemical identification and differentiation tests of bacteria can be manual or automatic, having commercially available manual multiple test systems to API (bioMérieux), Enterotube (BBL), Oxi / Ferm Tube (BD), RapID and MicroID systems (Remel), biochemical ID systems (Microgen).…”

Foodborne diseases are considered a relevant issue in health around the world due to their incidence, mortality and negative effects on the economic and productive sector. Fish is considered a food of high nutritional quality, being of global production, distribution and commercialization mainly for human consumption. Among the fish worldwide obtained from capture fisheries and mainly aquaculture for human consumption is Tilapia, due to the adaptability of this fish under cultivation conditions in addition to the fact that its meat is of quality and accessible economic value. Fish due to its composition, is highly susceptible to deterioration and contamination by different hazards throughout the food chain, putting the safety of products and public health at risk. Shigellosis is among the diseases that may be contracted from the consumption of food contaminated by bacteria of the genus Shigella spp.; food contamination is mainly related to inadequate or non-hygienic conditions and practices in the production, processing and handling of food. Therefore, the purpose of this review is to provide a general perspective of foodborne diseases, especially shigellosis, causal agents, conditioning factors, related foods such as fish, as well as control and preventive actions in order to protect the food safety and public health.

Vegetables, especially those eaten raw, have been implicated in several foodborne disease outbreaks. Since multiple vegetable matrices and hazards are involved, risk managers have to prioritize those with the greatest impact on public health to design control strategies. In this study, a scientific-based risk ranking of foodborne pathogens transmitted by leafy green vegetables in Argentina was performed. The prioritization process included hazard identification, evaluation criteria identification and definition, criteria weighting, expert survey design and selection and call for experts, hazard score calculation, hazard ranking and variation coefficient, and result analysis. Regression tree analysis determined four risk clusters: high ( Cryptosporidum spp., Toxoplasma gondii, Norovirus), moderate ( Giardia spp., Listeria spp., Shigella sonnei), low (Shiga toxin-producing Escherichia coli, Ascaris spp., Entamoeba histolytica, Salmonella spp., Rotavirus, Enterovirus) and very low ( Campylobacter jejuni, hepatitis A virus and Yersinia pseudotuberculosis). Diseases caused by Norovirus, Cryptosporidium spp. and T. gondii do not require mandatory notification. Neither viruses nor parasites are included as microbiological criteria for foodstuff. The lack of outbreak studies did not allow to accurately identify vegetables as a source of Norovirus disease. Information on listeriosis cases or outbreaks due to vegetable consumption was not available. Shigella spp. was the main responsible for bacterial diarrhea, but it has not been epidemiologically associated with vegetable consumption. The quality of the available information for all hazards studied was very low and low. The implementation of good practice guidelines throughout the entire vegetable production chain could prevent the presence of the identified hazards. The current study allowed the identification of vacancy areas and could help reinforce the need for performing epidemiological studies on foodborne diseases potentially associated with vegetable consumption in Argentina.
