“…It was observed that the culture areas in Pamantolon, Taytay were surrounded by houses built with low-cost materials with comfort rooms that don't have septic tank and very near the shore so runoff from terrestrial area could have contributed to the presence of coliforms. Chinnadurai et al (2020) proved that bacterial concentrations in shellfish correlate strongly with those in the waters. Their sampling sites (growing sites of shellfish) receive high levels of contaminants from drainage channels, open toilet drain, non-functional septic tank and livestock production areas, and they found similar high contamination in the shellfish from the areas.…”

Abalone is one of the most highly priced seafood delicacies and prepared in various dishes like breaded, soup, steamed and sashimi. They are susceptible to microbial contamination since it is eaten raw sometimes and pathogenic microorganisms can be hazardous to consumers. The present study was carried out to determine the coliform load and the presence of presumptive pathogenic bacteria in cage-cultured abalone in Taytay, Palawan, Philippines. The study was limited to the detection of coliform and some presumptive pathogenic bacteria in different parts of abalone such as gut, gills and mantle. The result of the study revealed that the count of coliforms present in the mantle and gills of abalone falls within the normal standard limit (7 – 21 MPN 100g-1 sample). On the other hand, the gut of abalone was beyond the standard limit (460 MPN 100g-1 sample). Moreover, the gut of abalone harbors Vibrio spp., Salmonella spp. and Shigella spp. and general enteric bacteria. Foodborne infections caused by Vibrio, Salmonella and Shigella are common in Asia.

“…Contamination of water bodies by wastewater is a fundamental problem worldwide. Te bacteria, parasites, and viruses from animals and humans reach the oceans through runof from roads, agricultural areas, and sewage discharges [46]. In addition, heavy rainfall may cause sewage overfows and drain leakages [47].…”

Bivalve molluscs are a good source of high quality protein and perform important ecological functions. Their ability to bioaccumulate materials in their soft tissues makes them suitable aquatic species for biomonitoring of environmental conditions. The discharge of treated and untreated sewage into the bivalve-growing areas is a concern. The aim of this study was to investigate the prevalence of bacterial microbiota in shellfish farms in Saldanha Bay harbour using pathogens commonly associated with shellfish-related foodborne disease outbreaks. Seawater and mussel samples were collected from five sampling points located in three sampling locations. Oyster samples were collected from the harbour deck immediately after harvesting by the farmers. The most probable number (MPN) method was used to enumerate E. coli and faecal coliforms. Cultural methods were used for the detection of Salmonella and Vibrio spp. The E. coli concentrations for 15 March and 14 July are <0.18 MPN/100 ml at all sampling sites and for 25 August, <0.18 MPN/100 ml for all sampling sites except sampling site SP2 (0.2 MPN/100 ml). Spikes were observed on the total MPN counts in winter. Salmonella and Vibrio spp. were not detected. However, other bacterial species were identified through their phenotypic profile using the VITEK 2 system. Based on the low E. coli-MPN concentrations, the study concluded that the molluscs were safe for human consumption. Further studies need to be conducted on the bacterial species identified.

“…In this type of wastewater, microbiological contamination during shellfish harvesting is usually identified by undertaking a sanitary survey. The samples of shellfish are tested for fecal coliforms [39]). The amount of fecal coliform can be elevated during the monsoon periods, and the bacterial concentration in shellfish has shown a strong correlation with other water quality parameters.…”

Wastewaters from various process industries, namely food and agricultural, sugar mill, brewery, milk, vegetable and fruit, and meat and fisheries processing industries and their wastewater effluents contain nutrients, organic matter, inorganic, heavy metals, suspended solids, and pathogens. The discharges of non-treated wastewater enter the nearby aquatic ecosystem (e.g., lakes, rivers) and are a significant concern due to the presence of different nutrients, competing ions and C containing pollutants. It causes excessive growth of algae, loss of habitat/species, and other negative impacts on human health/environment. In the present review, different treatment approaches have been discussed in utilizing these nutrients to synthesize value-added products such as biopolymer, biofuel, pigment, organic acid, or enzymes. These biopolymers can be used to prepare various food products/packaging materials. Dextran, chitosan, carrageenan, alginate, and pectin are good examples of non-food biopolymers. Besides these products, poly-β-hydroxybutyrate (PHB) synthesis from wastewater nutrients is reported as a new source of bio-nanocomposite materials/biopolymer-based coatings. In this review, the different treatment approaches are discussed, which are being used worldwide for the removal/recovery of nutrients, toxic pollutants, and the potential resource recovery of value-added products from wastewater.
