“…STEC, Salmonella spp., S. aureus and L. monocytogenes are regarded as high risk although low in infectious dose (Gizaw, 2019;Crotta et al, 2022). Moreover, since the exact source of contamination is not known, the mere detection of pathogens could indicate a contamination of the surroundings as well (Patiño et al, 2020). Therefore, studies that do not provide descriptions of microbial loads, but just indicate the presence of pathogens could be important indicators of food safety as well.…”

Background and aimInformal food establishments are an important source of food due to their increased affordability of products and convenience. Food security and safety are two key factors that must coexist for a proper functioning of the food system. In Latin America, the safety of food is less analyzed than food security, although it is central to people’s health, as well as to their personal sustainability. Since informal food establishments are popular food sources in Latin America, this research aims to examine the presence of foodborne pathogens in food products from such establishments.MethodsThis research will be conducted as narrative literature review, collecting data from all publications in Spanish-speaking countries in Latin America between January 1, 2018, and May 31, 2023. The databases searched were PubMed and Web of Science. The search included pathogens such as bacteria, parasites and viruses. The languages of the articles assessed were English and Spanish.ResultsThe analysis was based on 32 articles focusing on seven of all Spanish-speaking countries in Latin America. The pathogens found belonged either to a bacteria type, or to a parasite. No viruses were investigated within the selection of articles. The widest variety of pathogens was among bacteria. The most frequently identified bacteria belonged to the family Enterobacteriaceae. The food products examined ranged from animal products to fruit and vegetables, fish, seafood and already-prepared dishes or juices. The informal food establishments where the studies conducted their analyses were markets, backyard selling points, street establishments or convenience food stores.ConclusionIdentifying pathogens in food products commercialized at different informal retail points has impacts for the safety of the food from personal sustainability viewpoint. Therefore, efforts need to be directed toward better support of the informal food sector in their provision of safe food. Further investigation could trace the exact sources of infection, while public health officials can implement safety programs in cooperation with food vendors.

“…Other food sources could be involved in human invasive Salmonellosis infections in Colombia, however, this study provided evidence of foodborne clades associated with the poultry chain. Nevertheless, it is essential to provide regular WGS data from the poultry and other food chains but from other interfaces to generate a much more comprehensive analysis of Salmonella dissemination and its zoonotic dynamics in Colombia (71)(72)(73). WGS makes feasible the integration of data from foodborne clades domestically and globally, allowing institutions to respond more efficiently to health threats as they arise.…”

Foodborne diseases represent a link between environmental, animal, and human health interfaces from the One Health perspective. Whole genome sequencing (WGS) is becoming the gold standard in foodborne surveillance, worldwide. WGS than provides precision data from pathogens allows laboratories to resolve the genetic relations among all sources from One Health perspective, especially during outbreak investigations, getting insights into their transmission routes and pathogenicity.Salmonellaspp. is the most prevalent foodborne bacteria in Colombia, in 2020, 268 foodborne outbreaks were reported to National health institute (INS) and 3079 invasive and faecal salmonellosis samples from 81% of the Colombian geographical regions. Several studies in different food sources exhibited an increase of contamination withSalmonella, a public health concern due to the steady development of antimicrobial resistance associated to specific serovars. However, integration ofSalmonella spp. data including food-chain supply and clinical interfaces is very scarce in Colombia. This study carried out a national comparison ofSalmonellaisolates collected from food-chain supply and clinical sources. Using an epidemiological and phenotypic approach, we demonstrated the higher resolution of WGS compared with PFGE, routinely used inSalmonellasurveillance in Colombia. For example, the resolution of PFGE allowed the description of two main clusters of foodSalmonellaEnteritidis isolates which were expanded to eight clades by using WGS. Virulence factors and antimicrobial determinant genes observed in the foodborne clades should be considered a public health concern in Colombia. WGS is a technology that provides precise and valid evidence for the establishment of dissemination routes of foodborne high-riskSalmonellaclades, but it requires an integrative and continued collaboration between the stakeholders across the One Health interfaces to promote and support integrated real-time actions in public health.

“…Broccoli is another vegetable of significant economic and food security importance, with a yearly production of 2422 tons [3]. Most of this production relies on external inputs such as fertilisers and pesticides, whose residual effects can negatively impact both producers and consumers [4].…”

Diversifying agroecosystems enhance the sustainability of agricultural production and reduce input dependency during agroecological transitions. To achieve this objective, a study was conducted to assess the impact of intercropping and the introduction of flowering plant strips on land use efficiency and crop damage in a lettuce and broccoli association. The results indicated that the introduction of flowering plant strips alone led to a significant increase in land use efficiency, while intercropping alone did not have any such effect. The efficiency was measured using the land use equivalent ratio (LER), which consistently showed values greater than 1, suggesting a significant increase in efficiency. It should be noted that the presence of flower strips in the crop fields were found to increase the incidence of molluscs and Plutella xyllostella. Additionally, the competitive ratio analysis revealed that broccoli was more competitive than lettuce in the intercropping system. Therefore, farmers can increase the efficiency of land use and profitability by incorporating flower strips in the intercropping systems of broccoli and lettuce.
