“…Factors, such as densely populated areas and inefficient wastewater treatments, can be related to the prevalence of Salmonella in the marine environment. In line with this hypothesis, a study carried out on the coast of Colombia established a relationship between inefficient wastewater treatment systems and the presence of Salmonella in beach waters [34]. S. typhimurium is the second serotype most commonly associate with human salmonellosis in the European Union, and therefore highly populated coastal regions can suffer a potential contamination with human pathogenic Salmonella serotypes [35].…”

Salmonella spp. and antimicrobial resistant microorganisms are two of the most important health issues worldwide. In the present study, strains naturally isolated from mussels harvested in Galicia (one of the main production areas in the world), were genetically characterized attending to the presence of virulence and antimicrobial resistance genes. Additionally, the antimicrobial profile was also determined phenotypically. Strains presenting several virulence genes were isolated but lacked all the antimicrobial resistance genes analyzed. The fact that some of these strains presented multidrug resistance, highlighted the possibility of bearing different genes than those analyzed, or resistance based on completely different mechanisms. The current study highlights the importance of constant surveillance in order to improve the safety of foods.

A socio-ecological assessment of land-based contamination and pollution: The Magdalena delta, Colombia

2022

River mouth systems, such as estuaries and deltas are important earth system transitional zones linking the land and coastal marine systems. They funnel anthropogenic contaminants and pollutants from the activities in the river catchment into the marine environment. The present study is focused on the Magdalena River-mouth at Bocas de Ceniza where land-based contamination and pollution are important issues. These were subsequently analysed using an expanded DPSIR framework (Drivers Pressures, State, Impacts Responses). Based on export coefficients and secondary information, the loads of BOD, TSS, Nutrients and solid waste from different sources were identified and compared to prioritize their management within the study area. Findings suggest that contaminants generated in the study area may be insignificant compared to the inputs from the Magdalena River, but they can have a significant impact on the state of local ecosystems. Of all the sources analysed, agriculture and livestock are theoretically the largest contributors of nitrogen (i.e., 14.84 t d-1 and 48.99 t d-1) and phosphorus (i.e., 5.90 t d-1 and 19.46 t d-1) in the basin ‘Direct to the Caribbean’ and ‘Cienaga de Mallorquín’ (that altogether are identified as DtC+) and the ‘Western bank of the lower Magdalena’ (DtM-LM), respectively. In the case of BOD, domestic and industrial wastewaters contribute about 5.10 t d-1 and 98.43 t d-1 in the same basins. Contributions of faecal coliforms were more than 4 orders of magnitude higher in untreated wastewater, being 4.86 x1016 NMP d-1 and 1.78 x1016 NMP d-1 in the lower Magdalena and Caribbean catchments, respectively. Inadequately managed waste and plastic represent a serious problem for the Caribbean Basin. Solid waste generated within the study area and coming from the Magdalena basin and the Caribbean Sea, reaches the coast and deteriorates its visual quality, affects mangrove ecosystems, and generates impacts on coastal populations. By basin, the DtM-LM is where the greatest pollutant loads are generated. However, in terms of impact on human well-being, it is the DtC+ that bears the brunt where pressures are translated in impacts such as increased maintenance and cleaning cost of beaches, reduction or loss of tourism revenue, adverse health effects to vulnerable groups, reduce protection against natural hazards, increased living costs and loss of cultural values.

Dug wells are a source of clean water used by many people in Indonesia. Poor quality water can have negative effect on public health. This study was to obtain an overview of the bacteriological quality of water and the risk of water pollution of dug wells on Semau Island, Indonesia. The research design was a cross-sectional study. The research location was on Semau Island (8 villages), one dug well was taken for each village as a sample. Observations and laboratory examinations were conducted to determine environment risk factors, total coliform, Escherichia coli and total bacterial. The results showed that the total coliform in 6 samples exceeded standards, E. coli were found in all samples, the total plate number ranged 85-190 CFU/ml. The dug wells environment showed that 50% are at a distance of <10m from the source of pollution, 100% no waste water drainage, 62% there were cracks on the floor, 62% of the well 3 meters deep no plastered, 82% no fence. Some samples had poor bacteriological quality and environment risk factors for contamination, it is necessary to improve the facilities and environmental of the wells and treat water before consumption.
