Marin et al. [27] detected E. coli when researching the
bacteriological quality of Cynoscion squamipinnis and Lutjanus gutattus fish samples marketed in Costa Rica. Koo et al. [28] reported having isolated ETEC strain from rockfish sold in South Korea, and alerting to the presence of E. coli pathogen in seafood.
Akoachere et al. [29] performed phenotypic charac- terization of human pathogenic bacteria in fish from the coastal waters of South West Cameroon and identified 11 bacterial species, including E. coli Type 1 (20.8% of total strains). The samples were considered a source of human pathogenic, which makes it a case of public health implications. According to the authors, microbial pollut-ants contaminate the coastal water as well as the aquatic food sources, thus posing a substantially hazardous ex-posure to consumers.
The assertive that commercial fish and seafood may constitute repositories of multiresistant bacteria to anti- biotics was reported by Ryu et al. [30]. The authors found high index taxes of resistance to tetracycline (30.7%), streptomycin (12.8%), cephalothin (11.7%), ampicillin (6.7%) and ticarcillin (6.1%) in strains of E. coli iso-lated from fish and seafood collected from wholesale and retail markets in Seoul, Korea. Moreover, the au-thors found resistance genes for tetracycline (tetB and tetD), beta-lactams (blaTEM), aminoglycoside (aadA).
