“…In Scomber japonicus mackerel (the intestine and the stomach) or in Limanda herzensteini flat fish (the gills), P. vulgaris was stated as producing a big yield of intracellular and extracellular chondroitinase, which may be directed against the host connective tissues, containing mucopolysaccharide chondroitin [66]. Also, freshwater Nile tilapias ( Oreochromis niloticus ) from experimental freshwater aquaculture in Brazil [17] and tilapias from Lake Victoria, Kenya [107], were sporadically colonized by P. vulgaris or Proteus sp. Kumar et al [70] reported on P. hauseri as a causative agent of hemorrhage and mortality in a koi carp ( Cyprinus carpio ) farm in India.…”

Proteus spp. bacteria were first described in 1885 by Gustav Hauser, who had revealed their feature of intensive swarming growth. Currently, the genus is divided into Proteus mirabilis, Proteus vulgaris, Proteus penneri, Proteus hauseri, and three unnamed genomospecies 4, 5, and 6 and consists of 80 O-antigenic serogroups. The bacteria are known to be human opportunistic pathogens, isolated from urine, wounds, and other clinical sources. It is postulated that intestines are a reservoir of these proteolytic organisms. Many wild and domestic animals may be hosts of Proteus spp. bacteria, which are commonly known to play a role of parasites or commensals. However, interesting examples of their symbiotic relationships with higher organisms have also been described. Proteus spp. bacteria present in soil or water habitats are often regarded as indicators of fecal pollution, posing a threat of poisoning when the contaminated water or seafood is consumed. The health risk may also be connected with drug-resistant strains sourcing from intestines. Positive aspects of the bacteria presence in water and soil are connected with exceptional features displayed by autochthonic Proteus spp. strains detected in these environments. These rods acquire various metabolic abilities allowing their adaptation to different environmental conditions, such as high concentrations of heavy metals or toxic substances, which may be exploited as sources of energy and nutrition by the bacteria. The Proteus spp. abilities to tolerate or utilize polluting compounds as well as promote plant growth provide a possibility of employing these microorganisms in bioremediation and environmental protection.

“…bacterial infections play an important role as secondary infection and lead as a major risk that can result in very large losses of fisheries [22]. precaution should be taken to prevent water contamination during harvesting as well as post-harvest handling of fish, As well as the bacterial ecology of fish be linked to several environmental factors such as fish feed quality, handling, water pollution, transport and storage condition [23].…”

“…Recent studies in fish processing companies in Vietnam (Thi et al, 2014) and Kenya (Onjong et al, 2014b) observed high variability of Enterobacteriaceae on food contact surfaces and hands of the personnel as well as fish products. According to literature, possible causes of Enterobacteriaceae contamination are inadequate procedures of slaughter, handling, packaging, and storage (Boari et al, 2008;Okonko et al, 2008Okonko et al, , 2009) and ineffective cleaning of food contact surfaces like tables and equipment (BaggeRavn et al, 2003). Likewise, water and ice (Okonko et al, 2009;Shikongo-Nambabi et al, 2010;Mohamed et al, 2011), personnel (Mohamed et al, 2011), and reduced chlorine concentration of the dip after intensive use (Shikongo-Nambabi et al, 2011) or microbial buildup after an extensive use of the dip could be possible causes of contamination.…”

This study aimed at giving insight into microbiological safety output of a Hazard Analysis Critical Control Point (HACCP)-based Food Safety Management System (FSMS) of a Nile perch exporting company by using a combined assessment, FSMS-diagnosis and actual microbiological assessment. The FSMS diagnosis indicated FSMS activities at an average level operating in moderate-risk context level but with good system output. Likewise, microbiological assessment revealed a better system output with respect to pathogens (Vibrio cholerae, Listeria monocytogenes and Salmonella spp.) and faecal hygiene (Escherichia coli) as none of these were detected in any critical sampling location throughout the study. Although indicators of general process hygiene (that is, Enterobacteriaceae and TVC) exceeded regulatory limits and guidelines in raw materials and food contact materials, Staphylococcus aureus on operator's hands were beyond the general microbiological guidelines in the fish industry. Higher contamination levels of general process hygiene and personal hygiene indicators call for improvement on hygienic design, specific production and sanitation procedures, independent validation, process automation, and change in personnel recruitment criteria.
