  This project was carried out to evaluate the effect of metabisulfite sodium on microbial quality, shelf-life as well as residual of metabisulfite sodium in edible tissue of processed cultured shrimp during freezing storage. The samples were treated with 3% metabisulfite sodium for 10 minutes and were stored at -18 °C for 6 months. Then, the microbial quality of the samples was assayed. Results revealded a significant reduction (P<0.05) in total bacterial count and populations of staphylococci and coliform bacteria in the test and control samples. Moreover, contamination with Pseudomonas aeroginosa, Vibrio parahemolyticus and Escherichia coli was estimated below 10 CFU/g in the both test and control samples. According to the results, the amount of metabisulfite sodium residue in the treated shrimp samples was below the approved limit of 100 mg/kg. During the storage period a significant (P<0.05) difference was observed between the treatment and control groups. Absence of pathogenic bacteria in the treated samples together with the approved level of metabisulfite sodium residual in the final product, it was concluded that metabisulfite sodium treatment could be a suitable method for kepping the microbial quality of vannamei shrimp.
