Abstract
One hundred random samples of corned beef, canned luncheon, canned tuna and canned sardine (25 of each) were collected from different supermarkets and shops at Kafrelsheikh city for microbiological examination. The results indicated that the mean values of total anaerobic bacterial counts of corned beef, canned luncheon, canned tuna and canned sardine were 2.84x10³±0.76x10³, 9.10x10⁴±0.97x10⁴, 4.39 x10³±2.12x10³ and 7.16x10²±2.83x10² cfu/g respectively, with isolation of C. bifermentans, C. butyricum, C. fallax, C. perfringens, C. putrefaciens, C. sordelli, C. sporogenes and C. tertium by different rates.
On the other hand, the mean values of total aerobic sporeforming bacterial counts were 6.01x10²±2.15x10², 2.57x10²±0.32x10², 3.71x10²±0.89x10² and 1.34x10²±0.68x10² cfu/g and the mean values of total mold and yeast counts were 1.47x10²±0.53x10², 5.86x10²±0.90x10², 1.14x10²±0.56x10² and 6.90x10±3.11x10 cfu/g, for the examined samples of corned beef, canned luncheon, canned tuna and canned sardine, respectively.
