Abstract
Atotal of 120 random samples of fresh water fish, frozen mackerel
fish, smoked fish and salted fish (30 samples of each) were collected from many places at Cairo Governorate. The samples were transported directly to the laboratory with a minimum of delay to be examined mycologically.’ 7.1 Fresh water fish In fresh water fish, tile mean values of contamination with moulds and yeasts were 4.7 x 103 ± 1.4 x 103 and 7.1 x 103 ± 3.6 x 103 respectively. The mould genera isolated from fresh water fish were Abasidia spp., Alternaria spp., Aspergillus spp. (which further identified into A. flavus, A. fumigatus, A. niger andA. ochraceus), Cladosporium, Fusarium spp., Mucor spp., Penicillium spp. and Rhizopus spp. while the yeast genera isolated were Candida alb icons, Candida guillermondii, Candida tropicalis, Cryptococcus spp., Rhodotorula spp., Torulopsis spp. and Trichosporon spp. 7.2 Frozen mackerel fish
In frozen mackerel fWa, the mean values of contamination with
moulds and yeasts were 1.) x 103 ± 3.2 x 102 and 1.7x 103 ± 3.6 x 102,
respectively, The mould _a isolated from frozen mackerel fish were
Alternaria spp., Aspergillus spp. (which were further identified into A.
flavus, A. fumigatus, A. gljJpcus, A. niger, A. terreus and A. versicolor),
Cladosporium spp., Fusarium spp., Mucor spp., Paecilomyces spp.,
Pencillium spp., Rhizopus spp., and Trichoderma spp. While the yeast
genera isolated were Candida albicans, Candida guillermondii, Candida
pseudotropicalis, Candida parapsilosis, Candida tropicalis and
Rhodotorula spp. 7.3 Smoked fish In smoked fish, the mean values of contamination with moulds and yeasts were 3.5 x 103 ± 1.3 x 103 and 2.7 x 103 ± 3.8 x 102,respectively. The mould genera isolated from smoked fish were Alternaria spp., Aspergillus spp. (which were further identified into A. flavus, A. fumigatus, A. niger, A. terreus and A. versicolor), Cladosporium spp., Fusarium spp., Mucor spp., Pencillium spp., Rhizopus spp., and Trichoderma spp. While the yeast genera isolated were Candida krusei, Candida parapsilosis, Candida pseudotropicalis, Candida tropicalis, Cryptococcus spp., Rhodotorula spp., Saccharomyces spp. And Torulopsis. 7.4 Salted fish In salted fish, the DIC8Il values of contamination with moulds and yeasts were 1.8 x 103±3.&x 102 and2.8x 1Q3±7.6x 1Q2,respectively. The mould genera isol_ from smoked fish were Alternaria spp., Aspergillus spp. (which were further identified into A. flavus, A. fumigatus, A. niger, A. teI’f’f!USand A. versicolor), Cladosporium spp., Fusarium spp., Mucor sPf .• Paecilomyces spp., Pencillium spp., and Rhizopus spp., While the yeast genera isolated were Candida albicans, Candida krusei, Can~ parapsilosis, Candida pseudotropicalis, Candida tropicalis, Cryptococcus spp., Geotrichum spp and Rhodotorula spp. Accordingly the public health significance of isolated mould and yeasts and their sources of contamination as well as some measures and recommendations to control of such contaminants were discussed.
