Shellfish including shrimp and clams are consumed allover the world for their nutritionalvalue, however, handling in seafood markets may challenge their safety and quality.Shellfish products in the fish markets in Suez Governorate were evaluatedthroughchemical analysis of total volatile basic nitrogen value, thiobarbituric acid,histamine content, and some heavy metals residues. As well as, microbiological estimationof the total aerobic counts, Enterobacteriaceae counts, Escherichia coli counts, andStaphylococcus aureus counts, in addition of Salmonella detection. Results declared thatmore than half of the examined samples of shrimp and clams (gandofly) were fit forhuman consumption based on the permissible limits of the Egyptian standard. Otherwise,some gandofly samples contain high levels of total volatile basic nitrogen (TVB-N),thiobarbituric acid reactive substance (TBA), and may cause scombroid food poisoningwith elevated histamine level. The levels of cadmium, lead, and zinc in shellfish samplesunder study was different with the sequence: Zn>Pb>Cd. Bacteria including E. coli andStaphylococcus aureus were identified. The analysed samples in this study were judged asmedium/good quality market samples as more than half of the examined samples werewithin the Egyptian standard and may indicate that trading of shellfish at Suez marketswent under abuse storage temperature.
