  • Pesticide and Pathogen Contamination of Vegetables in Ghana’s Urban Markets

    Abstract  The objective of the study was to determine and compare the current level of exposure of the Ghanaian urban population to hazardous pesticide and fecal coliform contamination through the consumption of fresh vegetables produced in intensive urban and periurban smallholder agriculture with informal wastewater irrigation. A total of 180 vegetable samples (lettuce, cabbage, and ...

  • Presence and persistence of wastewater pathogen Escherichia coli O157:H7 in hydroponic reactors of treatment wetland species

    Treatment wetlands (TWs) efficiently remove many pollutants including a several log order reduction of pathogens from influent to effluent; however, there is evidence to suggest that pathogen cells are sequestered in a subsurface wetland and may remain viable months after inoculation. Escherichia coli is a common pathogen in domestic and agricultural wastewater and the O157:H7 strain causes ...

  • The viability of treated piggery wastewater for reuse in agricultural irrigation

    Background The swine production is a very important economic matter, occupying prominent position in the worldwide market. However, it appears as the greater impacting activity for the water resources. Researches point a swine manure production of 105.6 million m3/year in Brazil, which resulted in a piggery wastewater rich in solids, nutrients, heavy metals, and pathogens. Moreover, ...

  • Wastewater retreatment and reuse system for agricultural irrigation in rural villages

    Climate changes and continuous population growth increase water demands that will not be met by traditional water resources, like surface and ground water. To handle increased water demand, treated municipal wastewater is offered to farmers for agricultural irrigation. This study aimed to enhance the effluent quality from worn-out sewage treatment facilities in rural villages, retreat effluent ...

  • Use of Fat, Oil and Grease Waste as an Agricultural Soil Conditioner

    Wastewater from the food processing and food service industries can contain large quantities of fat, oil and grease (FOG). Most North American jurisdictions have bylaws limiting the concentration of oil and grease in sewer discharges. As municipal source control efforts become more aggressive, quantities of FOG waste requiring proper treatment/disposal will increase. At the same time access to ...


  • Using native riparian barriers to reduce Giardia in agricultural runoff to freshwater ecosystems

    Waterway degradation in agricultural settings is caused by direct and diffuse sources of pollution. Waterway fencing focuses on reducing direct faecal contamination, but the extent to which it reduces overland surface runoff of pathogens is unknown. This study evaluated the potential of four riparian treatments to reduce Giardia in saturation excess surface runoff entering the waterway. Treatment ...

  • Detection of universal GMOs marker 35S-Promoter and tNOS-Terminator by using qTOWER 2.2, real-time PCR

    1. Introduction Due to dramatically increment of human population, many countries realized that food insufficiency will be a big issue during the next decade. To improve agriculture and livestock, they started producing genetically modified organisms (GMO) with high productivity of yield and a resistance to insects and pathogenic ...

  • Irrigation by Sewage Effluents in Yemen

    Yemen is the least advanced country among Middle East Countries in the sewage reuse and safety control. The current sewage effluent quality in Yemen is generally poor as none of the existing sewage treatment plants produces effluents comply with the effluent quality regulations. The oxidation and stabilization ponds are considered the most appropriate for the warm climate conditions in the ...

  • The effect of different percentages of bulking agent (sawdust) on microbial quality of faecal sludge

    The use of raw sludge spread on land as conditioner and fertilizer has been practised over the years in urban agriculture. However, this raw sludge (biosolids) is associated with a potential health risk as a result of the pathogenic microorganisms it contains. The study considered the dewatering of faecal sludge (FS) mixed with sawdust to produce biosolids that can be applied as manure for ...

  • Advances in control of postharvest diseases in tropical fresh produce

    With increased global trade, fresh produce is increasingly being moved over vast distances to foreign markets. This requires effective cold chain and product management practices to ensure premium quality fresh produce with increased shelf life. Product safety has now also become an additional minimum requirement for market entry. Producers should therefore take cognisance of the impact ...

  • Risk assessment and management of animal disease-related biosecurity

    Animal agriculture is vulnerable to both intentional and unintentional biological threats. Outbreaks, especially intentional attacks, could cause enormous consequences extending well beyond agriculture. Nations, including the USA, are consolidating and coordinating efforts to protect against these biological threats. The efforts employed largely fall into the categories of ex ante ...

  • Use of plant growth-promoting bacteria for biocontrol of plant diseases: Principles, mechanisms of action, and future prospects

    Pathogenic microorganisms affecting plant health are a major and chronic threat to food production and ecosystem stability worldwide. As agricultural production intensified over the past few decades, producers became more and more dependent on agrochemicals as a relatively reliable method of crop protection helping with economic stability of their operations. However, increasing use of chemical ...

  • Managing waste from confined animal feeding operations in the United States: the need for sanitary reform

    Confined food-animal operations in the United States produce more than 40 times the amount of waste than human biosolids generated from US wastewater treatment plants. Unlike biosolids, which must meet regulatory standards for pathogen levels, vector attraction reduction and metal content, no treatment is required of waste from animal agriculture. This omission is of concern based on dramatic ...

  • Playing hide and seek below the soil

    Below the soil of a diverse grassland area you’ll find a jungle of plant roots. It is also home to a wide variety of bacteria and fungi, of which some are pathogenic and looking for a host in the tangle of roots. It appears that this is much more difficult when there is a larger diversity of plants as the host plant is more able to hide among the varied crowd. Greater plant diversity ...

  • Crop protection 2.0: reducing environmental impact in the EU Is it feasible?

    By 2023 all EU member states must be complying with more stringent guidelines related to Integrated Pest Management (IPM). “The essence of the new guideline is reducing the environmental impact of pesticides,” says Piet Boonekamp, manager of the Bio-interactions and Plant Health business unit at Wageningen UR. “In principle this European goal can be achieved, as has been shown ...

  • Grain legumes in northern great plains

    Cropping systems in the Northern Great Plains have shifted from fallow-based to legume-based systems. The introduction of grain legumes has impacted soil organisms, including both symbiotic and nonsymbiotic N-fixing bacteria, pathogens, mycorrhizae and fauna, and the processes they perform. These changes occur through effects of legume seed exudates, rhizosphere exudates, and decomposing crop ...

  • Minimizing health risks during secondary effluent application via subsurface drip irrigation

    Health risks posed on consumers due to the use of agricultural products irrigated with reclaimed wastewater were assessed by numerical simulation. The analysis is based on defining of an Exposure Model (EM) which takes into account several parameters: (i) the quality of the applied wastewater, (ii) the irrigation method, (iii) the elapsed times between irrigation, harvest, and product ...

  • Using Compost To Control Plant Diseases

    Losses due to soilborne diseases on some greenhouse, nursery and vegetable crops can amount to thousands of dollars per acre annually. Until the 1930s, organic amendments — consisting of animal and green manures, coupled with crop rotation — were principal methods of control. But these approaches were largely abandoned for reasons of cost and inconvenience after commercial fertilizers and the ...
