This study was aimed to evaluate some dried dairy drinks as salep, hot chocolate and coffee milk powder. A total of 75 random samples (25 each) were purchased from different dairy shops and supermarkets in Assiut city, Egypt. Each sample was microbiologically examined in both forms; powdered form (as it was packed) and reconstituted form (as manufacturing instructions) as well as isolation of Bacillus cereus and detection of its toxigenic genes (cytK, and hblC) using PCR technique was performed. The obtained results showed that the average psychrotrophic counts in the powdered form were 1.2x103, 3.6x102 and 80cfu/g, respectively; and the counts in the reconstituted form were 1.25x104, 1.69x104 and 7.8x103cfu/g, respectively. Moreover, the average thermophilic counts in the powdered form were 2.68x103, 40 and 40 cfu/g, respectively; and in the reconstituted form were 6.8x102,40 and |
