A survey of microbial flora of partially processed periwinkles (Tympanotonus fuscatus) sold in six markets in Port Harcourt was undertaken for twelve weeks. Results show that all samples of periwinkles were contaminated with Staphylococcus aureus, Bacillus sp., Escherichia coil, Staphepidermidis sp., Micrococcus sp., Pseudomonas sp., and Klebsiella sp. Staphylococcus aureus was the most predominant 24.9% while Klebsilella sp. was the least 5.80%. The occurrence of Staphylococcus aureus, Bacillus sp., and Escherichia coil is indicative of a high pathogenicity and health hazard in consuming periwinkles. The need to critically re-examine our public health standards in the markets is advocated.
