In: Assiut Veterinary Medical Journal 2009.v.55(122)Summary: A total of 80 random samples, forty of each of pasteurized full cream and skimmed milk were collected from local Egyptian markets. Samples were screened for the occurrence of Bacillus cereus. The incidence and total count of B. cereus in the different samples at the sterile opening were evaluated. 3 (7.5%) B. cereus positive samples were detected when the samples analyzed early. All milk samples were stored at 5 °C and evaluated for B. cereus up to their expiry date (at 72 "C for 15 s). No increase in incidence and count of B. cereus were observed during the first 8 da)'1l of Slorage at soc bm thereafter, an increase in the incidence and population of the microorgllllism with storage time was observed. B. cereus was detected in 19 (47.5%) llIld 10 (25%) of the investigated pasteurized full cream and skimmed milk samples, respectively at the end of refrigerator storage.
