“…Application of wastewater weather treated, raw, inadequately treated or thinned for irrigation purposes is a common practice in rural and urban areas [98]. Water scarcity in certain regions of the world such as sub-Saharan Africa amidst other factors like too much dependability of limited water source, proximity to a water source and the availability of nutrients has forced so many farmers to resort to the use of wastewater for the irrigation of fresh produce.…”

Disease outbreaks caused by the ingestion of contaminated vegetables and fruits pose a significant problem to human health. The sources of contamination of these food products at the preharvest level of agricultural production, most importantly, agricultural soil and irrigation water, serve as potential reservoirs of some clinically significant foodborne pathogenic bacteria. These clinically important bacteria include: Klebsiella spp., Salmonella spp., Citrobacter spp., Shigella spp., Enterobacter spp., Listeria monocytogenes and pathogenic E. coli (and E. coli O157:H7) all of which have the potential to cause disease outbreaks. Most of these pathogens acquire antimicrobial resistance (AR) determinants due to AR selective pressure within the agroecosystem and become resistant against most available treatment options, further aggravating risks to human and environmental health, and food safety. This review critically outlines the following issues with regards to fresh produce; the global burden of fresh produce-related foodborne diseases, contamination between the continuum of farm to table, preharvest transmission routes, AR profiles, and possible interventions to minimize the preharvest contamination of fresh produce. This review reveals that the primary production niches of the agro-ecosystem play a significant role in the transmission of fresh produce associated pathogens as well as their resistant variants, thus detrimental to food safety and public health.

“…(11 to 1.4 × 10 4 CFU/100 mL) [99]. However, adequate treatment of wastewater is only done in a few cases because the procedure is costly and time overwhelming [98]. Studies have indicated that only about 10% of wastewater is treated adequately in growing countries [13].…”

“…Concerning other experiences, the identification of reliable and feasible areas for treated wastewater irrigation has a positive impact on the overall water balance and slightly reduces the water "footprint" of agriculture (Hoekstra et al 2011), even if the impact is mostly near urban areas. The identification of reliable areas could also contribute to a healthy impulse of new norms and policies, especially given the context in most Latin American countries, where lack of legislation, deficits in sanitation infrastructure, and weak governmental institutions support unplanned and informal reuse schemes, thus intensifying the negative effects of the practice (Gatto et al 2015).…”

A model of land suitability analysis for irrigation with treated domestic wastewater is presented. The model integrates tools of Multi-Criteria Evaluation with Geographical Information Systems. Several criteria were selected to adapt the model to the conditions and characteristics of the case study. The adaptation process included field visits, a bibliographical review, and personal interviews with local actors and experts. Six constraints and 10 factors were selected and 3158 hectares suitable for the activity were identified. The areas were classified into three categories of aptitude, representing high fitness sites close to the current wastewater treatment plant. The developed tool allowed us to integrate different criteria to assess site suitability for wastewater reuse, with the advantage that the tool can be adapted to other regions and/or objectives.

“…Cette forte minéralisation est due à une richesse en minéraux de divers déchets provenant des activités anthropiques et également à la concentration de ces minéraux résultant de l'évaporation d'une partie de l'eau en saison sèche. Les TDS, quant à eux, permettent de connaître la quantité de matières dissoutes des éléments tels que le calcium, le magnésium, le sodium, les chlorures et les sulfates (Ndinwa et al, 2012). Les valeurs du TDS des eaux évoluent dans le même sens que la conductivité.…”

REMERCIEMENTS Les auteurs expriment leur gratitude à l'Ecole Normale Supérieure de Natitingou de l'Université Nationale des Sciences, Technologies, Ingénierie et Mathématiques d'Abomey qui a financé cette étude. RESUMELa présente étude s'est intéressée à la variation saisonnière de la qualité des eaux d'irrigation et des légumes produits sur le site maraîcher de Bawéra. Des enquêtes sociologiques ont été effectuées pour obtenir des informations auprès de 30 maraîchers sur les stratégies de gestion de l'eau en saison sèche. Des analyses physicochimiques et microbiologiques des eaux d'irrigation et des légumes ont été effectuées. Les teneurs en métaux lourds (cadmium, plomb, arsenics et cuivre) et en coliformes fécaux et totaux ont été recherchées. Les données recueillies ont été analysées par le logiciel Statistica version 7.1. Les résultats des enquêtes indiquent que les eaux usées des collecteurs de la ville et les eaux de puits sont utilisées pour l'irrigation des cultures avec une utilisation plus accrue des eaux usées pendant la saison sèche. Les analyses physicochimiques des eaux d'irrigation ont montré une forte variation des paramètres physicochimiques suivant les saisons. Les concentrations du cuivre et du plomb sont plus élevées dans les eaux d'irrigation et les légumes pendant la saison sèche. Les eaux d'irrigation et les légumes ont des teneurs en coliformes totaux et fécaux dépassant les normes requises. Le recours à ces légumes constitue une menace pour la santé des consommateurs. © 2018 International Formulae Group.

Sci. 12(2): 781-795, 2018 782 Seasonal variation of physicochemical and microbiological quality of irrigation water and vegetables at the Bawera market garden site and associated health risks ABSTRACTThe present study investigated the seasonal variation of the quality of irrigation water and vegetables produced at the Bawéra market garden site. Sociological surveys were carried out to obtain information from 30 market gardeners on water management strategies during the dry season. Physicochemical and microbiological analysis of irrigation water and vegetables were carried out. The contents of heavy metals (cadmium, lead, arsenics and copper), faecal and total coliforms were assessed. Data collected were analysed using Statistica version 7.1 software. Results from surveys indicate that wastewater from city collectors and well water are used for crop irrigation with increased use of wastewater during the dry season. The physicochemical analysis of the irrigation water showed a strong variation of the physicochemical parameters according to the seasons. Concentrations of copper and lead are high in irrigation water and vegetables during the dry season. The contents of total and faecal coliforms in irrigation water and vegetables exceed the required standards. The use of these vegetables poses a threat to consumer's health.
