Abstract
Fungi isolated from sun dried Rastrineobola argentea are associated with deterioration of the fish and is of public health importance. These may be as a result of inadequate sun drying, handling and storage, thus, the mycological quality of R. argentea sold in markets in Owerri metropolis was studied. A total of five markets were studied from which fifty retailers were sampled randomly and systematically. A sample of 20 g of R. argentea was collected from each participant. Samples were cultured on Sabourand dextrose agar to enumerate and identify the fungal isolates using cultural and microscopic methods. Analysis of variance (ANOVA) was used to determine the differences in the succession of fungi between and within markets at 5% level of significance. The results obtained showed that five fungal genera were isolated.These were; Aspergillus species 19 (44%), Candida species 11 (18%), Penicillium species 9 (28%), Rhizopus species 6 (18%) and Mucor species 5 (10%). The presence of mycotoxin producing species such as Aspergillus and Penicillium in the samples posses a real health risk through consumption or directly through contact with the fish products and therefore measures should be taken to improve their quality.
