“…Moreover, these studies proved how viruses are commonly resistant to conventional wastewater treatment processes and disinfection, and they can be spread in the environment by reclaimed wastewater effluents [103]. Furthermore, they are present in domestic wastewater and could be transmitted to the environment because of their low removal in conventional WWTPs and their long-time survival in the environment [104]. Some studies have been focused on asking about these specific health risks in order to know if they are perceived by both farmers and the public.…”

The successes and failures of water reuse schemes are shaped by complex interrelationships between technological, economic, and socio-political factors. However, it has long been recognized that the main challenges to more effective water management are largely social rather than technical. This article reviews the recent literature (2007–2017) to analyze driving factors associated with farmers’ concerns and public perception of reclaimed wastewater for irrigation. The aim of the paper is to synthetize how both environmental and health risks and the yuck factor could be addressed in order to promote mutual understanding between farmers and the public. Results show: (1) how farmers and the public perceive environmental and health risks in a similar way, (2) how the yuck factor is more noticeable for the public than farmers, and (3) how constructed wetlands, reclaimed water exchange consortiums, product certification, and direct site visits to water reuse infrastructure could be promoted in order to foster understanding between farmers and the public. The article concludes by providing key research questions for managers and public authorities relating to how to focus on the study of technical and social issues related to water reuse.

“…However, there are also reports of severe outbreaks of acute gastrointestinal disease, often in children under 5 years [58,59]. Enteroviruses in particular are frequently detected in environmental samples and waste water used for irrigation [60]. It seems that most mammal species harbour their own astro-, entero-and kobuviruses [56,61].…”

Purpose of Review The purpose of this review is to provide an update on recent literature and findings concerning selected foodborne viruses. Two groups of viruses were selected: (a) the most important viruses contaminating food, based on numbers of publications in the last 5 years and (b) viruses infecting sources of food that might have an impact on human health. Recent Findings Important foodborne viruses such as norovirus, hepatitis A and rotavirus are usually "only" contaminating food and are detected on the surface of foodstuffs. However, they are threats to human public health and make up for the majority of cases. In contrast, the meaning of viruses born from within the food such as natural animal and plant viruses is still in many cases unknown. An exception is Hepatitis E virus that is endemic in pigs, transmitted via pork meat and is recognised as an emerging zoonosis in industrialised countries. Summary Even though the clinical meaning of "new" foodborne viruses, often detected by next generation sequencing, still needs clarification, the method has great potential to enhance surveillance and detection particularly in view of an increasingly globalised food trade.

“…The number of diarrhoeal outbreaks associated with pathogenic protozoa in wastewater is rather low in developing countries (Bos et al 2010). Viruses are a concern for water reuse, because of their persistence in the environment and low-dose infectivity (Moazeni et al 2017). Bacteria are a concern because most treatment systems in developing countries do not aim for significant bacteria removal from wastewater (Bos et al 2010).…”

Wastewater irrigation is a common practice in developing countries due to water scarcity and increasing demand for food production. However, there are health risks and ecological risks associated with this practice. Small-scale wastewater treatment plants (WWTPs) intend to decrease these risks but still face management challenges. This study assessed how the management status of five small-scale WWTPs in Cochabamba, Bolivia affects health risks associated with consumption of lettuce and ecological risks due to the accumulation of nutrients in the soil for lettuce and maize crops. Risk simulations for three wastewater irrigation scenarios were: raw wastewater, actual effluent and expected effluent. Results showed that weak O&M practices can increase risk outcomes to higher levels than irrigating with raw wastewater. Improving O&M to achieve optimal functioning of small-scale WWTPs can reduce human health risks and ecological risks up to 2 log 10 DALY person −1 year −1 and to 2 log 10 kg nitrogen ha −1 accumulated in soil, respectively.
