“…A study in Vietnam corroborates this notion, where there was no significant difference found in the number of presumptive thermotolerant coliforms in the gut content and muscle tissue of fish raised in wastewater-based ponds and non-wastewater-based ponds [10]. Fattal et al (1992) and Edwards (2000) reported similar findings [11,12].…”

Households’ Willingness-to-Pay for Fish Product Attributes and Implications for Market Feasibility of Wastewater-Based Aquaculture Businesses in Hanoi, Vietnam

A choice experiment was used to assess households' willingness-to-pay (WTP) for informational attributes (sources of water used to rear fish, and certification) of fish products in Hanoi, Vietnam. The study showed that households' purchasing decisions are influenced by their access to information of food product attributes and ascribe an economic value to it. The results indicated that households are willing to pay 51% (USD 1.11 per kg) above the prevailing market price of fish for information to know if wastewater is used to rear the fish they consume. Similarly, they are willing to pay 20% above the prevailing market price of fish (USD 0.43 per kg) to know if freshwater is used as a rearing medium. It is important to note that the increased marginal WTP is for information on whether the fish they consume is raised in wastewater over freshwater. This supports the notion of households' concern over the safety of consuming wastewater-raised fish. Households are also willing to pay 65% (USD 1.42 per kg) above the prevailing market price for certified fish. Based on the cost of fish certification and WTP estimates, we found a total economic benefit of USD 172 million for the implementation of a wastewater-raised fish business model in Hanoi. The demand for wastewater-raised fish is likely to be affected by households' perception of certification by a trusted government agency, source of water used to raise the fish, age, income and household size.

“…High numbers of E. coli O157:H7 were detected from the internal organs. A similar pattern was observed earlier on tilapia exposed to polluted water containing E. coli (Fattal, Dotan, & Tchorsh, 1992). The high numbers of pathogen in the internal organs can cause a potential hazard.…”

“…Such complex microbial community found in treated WWTP effluents, although significantly reduced (particularly in fecal indicator bacteria), might still contain pathogenic bacteria which present a threat to fish living downstream (Topić Popović et al, 2015). On the other hand, fish inhabiting microbiologically polluted bodies of water can be contaminated by human pathogens and, if used for human consumption, may pose a risk to public health (Fattal et al, 1992). Microbiological examination and monitoring is commonly used worldwide to ensure the safety of a range of water sources whereby contamination with excreta could pose health risks.…”

Wastewaters from a treatment plant discharging into a canal harboring fish may present sources of microbiological hazard for wild fish. Such fish, inhabiting microbiologically polluted bodies of water, can be contaminated by human pathogens and, if used for human consumption, may pose a risk to public health. Hence, in this work the aim was to identify tested strains from tissues of wild fish living in the receiving water bodies, captured from locations up to 12 km from the point of discharge of treated water of town Virovitica in order to assess the bacterial threat of the WWTP on fish and potentially on public health. A rather rich diversity of bacterial genera was isolated from gill tissues and internal organs. The most frequent isolate was Aeromonas hydrophila which has gained public health recognition as an opportunistic pathogen. Vibrio cholerae, an indicator bacterium for aquatic contamination, was retrieved from all investigated tissues. Opportunistic human pathogens as well as some zoonotic agents were also retrieved from fish tissues (Enterobacter amnigenus, Acinetobacter spp., Ochrobactrum anthropi, Pseudomonas aeruginosa, Flavimonas (Pseudomonas) oryzihabitans, Shewanella putrefaciens and others). Public health hazard is particularly pronounced regarding local recreational fishermen who fish out, handle and consume fish from respective waters.
