“…E. coli was detected in all bivalve samples analysed indicating that contamination is associated with human activities as the major source of pollutants in this area. The result from this study was similar to the findings observed by Udoh et al (2017) on freshwater clam from Cross River, in Nigeria. E. coli has been implicated in acute diarrhea and gastroenteritis particularly serotypes such as 0148, 0157 and 0124.…”

The presence of bacterial pathogens in bivalve shellfish harvested from the marine ecosystem globally has continued to raise serious food safety concerns, thereby undermining the nutritional and health benefits derived from their consumption. Four species of bivalve shellfish: Bloody cockle (Anadara senilis), Donax clam (Donax rugosus), Knife clam (Tagelus adansonaii) and Mangrove oyster (Crassosstra gasar) harvested from the brackish waters of the Niger Delta were assessed for their bacterial pathogens. Standard methods of analysis were employed to assess microbiological hazards accumulated by shellfish species. The results of the microbiological analysis revealed that the total viable count (TVC) was lower than the recommended limit (5.7 log cfu/g) for fresh bivalve shellfish while Vibrio cholerae, Vibrio parahaemolyticus, Salmonellaspp, Shigellaspp, Listeria monocytogenes and E. coli were far above the stipulated FDA standard for molluscian shellfish. The loads of microbiological hazards in bivalve species indicated that in all the locations, Bloody cockle and Donax clam accumulated more bacterial pathogens while the samples harvested from Ibeno and Iko Town brackish waters were lower in pathogenic loads when compared to shellfish harvested from Andoni and Bonny location. The result obtained in this study is of public health importance since, it will serve as a guide towards improved processing techniques and stimulate actions towards the development of novel surveillance as well as, prevention and control strategies, that will help to reduce foodborne disease outbreaks associated with shellfish.

“…Additionally, seafood may become contaminated during handling, processing, or preparation. Furthermore, microbiological evaluation of shellfish has shown that they habour many pathogenic microorganisms that have been implicated in outbreak of foodborne diseases in many part of the world including Nigeria, where it is highly consumed [10]. These illnesses include Typhoid fever, Cholera, diarrhoea and other digestive disorders [6,11].…”

Aim: Enumeration of bacterial counts is an important index of assessing the safety and quality of food products. This study aimed to investigate the occurrence of pathogenic bacteria in white shrimp samples obtained from major markets serving consumers in Calabar. Study Design: This study was a cross sectional study conducted between April 2017 and April 2018. Methodology: One hundred and twenty (120) samples of smoked dried Nematopalaemon hastatus (white shrimp) were analyzed for the presence of bacterial pathogens. Bacterial loads and identification of isolated organisms was determined using standard microbiological methods. Results: The results showed that 66.7% of the analyzed shrimps had aerobic bacterial counts exceeding the upper permissible limit (<1.0x106Cfu/g) and 56.7% had unsatisfactory (˃20Cfu/g) Vibrio counts. The study revealed the presence of different bacteria genera namely Klebsiella, Salmonella, Pseudomonas, Serratia, Vibrio, Citrobacter, Proteus, Aeromonas, Streptococcus, Escherichia, Coagulase-negative Staphylococci (CoNS), Enterobacter and Bacillus. Predominant organism was Salmonella spp (26.7%), followed by Vibrio spp (21.7%) while the least isolated organisms were Bacillus spp and Coagulase-Negative Staphylococci (1.7%) each. The occurrence of high counts of pathogens in seafood may cause food poisoning; especially in individuals who consume this seafood raw, or lightly or insufficiently cooked. Conclusion: Hence, seafood should be processed and packaged under standard hygienic conditions to reduce the risk of microbial contamination. In addition, public health awareness campaign targeted at consumers and vendors should be optimized with frequent monitoring by regulatory agencies.
