Growing volume of washed vegetables in Europe and Lithuania means that more drinking water is consumed and more wastewater is produced. Farmers, who engage in washing vegetables, face the problems of wastewater treatment, wastewater storage and utilization. Wastewater released to the environment from their farms would meet hygiene and environmental protection criteria. The aim of the study was to assess the contamination of the root vegetable wash water and to evaluate the possiblity of cleaning of wastewater in the land-based treatment system consisting of one constructed wetland and two biological ponds. The contamination of wastewater, produced by washed root vegetables, in Lithuanian farms was measured according to suspended solids (SS), biochemical oxygen demand (BOD), chemical oxygen demand (COD), total nitrogen and total phosphorus. Pollution of the wash water and wastewater was evaluated comparing the mean values with legislative limit values and with typical sewage contamination values. In all farms wastewater of initial root vegetables washing was treated in settling basins. Wastewater of one carrots washing farm was treated in the land-based wastewater treatment system consisting of surface flow constructed wetland and two biological ponds. Efficiency of the wastewater treatment in this system was according to suspended solids 90%, BOD7 -97%, CODCr -92%, total nitrogen -98% , total phosphorus -97%. The result shows, that the natural wastewater treatment system is suitable for farms, that wash and produce vegetables, but before releasing wastewater to the environment, it has to be settled.

“…For instance the WSP framework recommends the (Davison et al, 2005). Examples of this type of approach can be found in WSP developed for water supply (Guan, 2008;Simazaki, 2008), hospitals (Dyck et al, 2007) and the food processing industry (Casani and Knøchel, 2002). For example, should there be a case of 'disposal of hazards', described as FM-1 in the model (Fig.…”

Key words: Water scarcity; Augmentation; Risk assessment; Chemicals; Heatmap Abstract This paper describes research undertaken to develop an approach for undertaking an initial hazard assessment and risk characterisation for a proposed indirect potable reuse scheme, as part of the water safety plan recommended by the by the World Health Organization. The process involved a description and evaluation of the catchment, which was the sewerage system supplying the sewage treatment works that would provide the effluent to supply the pilot scale indirect potable reuse water treatment plant. Hazards, sources and barriers throughout the proposed system were identified and evaluated. An initial assessment of the possible hazards, highlighted chemical hazards as predominating, and assessment of risks, using a heat map as output, categorised most hazards as medium or high risk. However, this outcome has been influenced by a precautionary approach which assigned a high likelihood to the occurrence of hazards where no data was available on their occurrence in the system. As more data becomes available, and the waster safety plan develops, it is anticipated that the risk heat map will become more specific. Additionally, high quality targets, to drinking water standards, have been set, although water from the potable reuse plant will be discharged to receiving waters where it will undergo natural attenuation prior to further treatment to potable standards before distribution. The assessment has demonstrated the usefulness of the approach where data is initially limited, in generating a heatmap allowing for prioritisation of hazards to a practical level.

“…A literatura aponta para a importância da implementação do sistema APPCC na produção de alimentos, que abrange a indústria alimentícia [12,13,14,15] até a produção de alimentos em restaurantes e estabelecimentos comerciais [16,17,18] . Na produção de sushis e sashimis, a adoção de Boas Práticas e a implantação do APPCC são essenciais para garantir a qualidade higiênico-sanitárias destes alimentos, principalmente devido à presença dos pescados crus, que possuem características intrínsecas necessárias à proliferação de microrganismos patogênicos, como pH próximo à neutralidade, elevada atividade de água e elevado teor de nutrientes [19] .…”
