62 karish cheese, mesh, and pickles samples were collected from Alexandria markets. The samples were examined bacteriologically and parasitologically. The results of the study indicate that the total plate of karish showed an average of 17x10[6]. Coliforms were found in all samples with an average of 79x10[7]/100 gm. 60% were identified as Escherichia Coli. The pH average was 3.6. In mesh sample bacteriological examination was negative. Pickles samples showed that, pH average of 8.6 and total plate count average of 4.2x10[6] and coliforms average of 28x10[3]/100 gm. Eschrichia coli was isolated from all the samples. Karish cheese, mesh cheese and pickles were infested by larvae of P. casei, M. domestica and Calliphora spp. E.coli cyst was found in .15.4% of karish cheese, while E.histolytica cysts were in 16.5% in pickles samples
