Total plate count and coliform levels in Nigerian periwinkles from fresh and brackish water


, : Total plate count and coliform levels in Nigerian periwinkles from fresh and brackish water. Food control 8(2): 87-89

Three species of freshly harvested Nigerian periwinkles — Tympanotonus fuscatus T. fuscatus var radula (both of brackish water habitat) and Pachymelinia bryonensis (a fresh water species) — were evaluated for bacteriological quality using aerobic plate counts and coliform counts. Results showed that all the periwinkles contained unacceptable levels of bacteria with P. bryonensis carrying up to 8.90 ± 1.93 mean log cfu/g meat. The levels of coliforms in the shellfish were generally high, ranging from 89.6% of the total load in T. fuscatus var. radula to 90.5% in T. fuscatus. No significant difference (P > 0.05) was detected between the periwinkles with respect to both SPC and coliform count. Bacterial genera identified in the molluscs included Bacillus, Salmonella, Klebsiella, Micrococcus, Shigella, Pseudomonas, Escherichia and Staphylococcus.
