This study identified, evaluated, and controlled hazards which are significant for food safety in an Alexandria company for puffed snacks industry. Results from the evaluation of Good Manufacturing Practice [GMP] and sanitation procedures after HACCP showed that the plant total score percentage of the checklist increased from 69.0% [low hazard plant] to 94.0% after Hazard Analysis and Critical Control Point [HACCP] [no hazard plant]. The microbial counts before HACCP of puffed snacks products were higher than those after HACCP. The aerobic bacterial count of stored end product of puffed snacks decreased from 7.0*10±9.5*10 to 1.6*10±2.0*10 CFU/g and mold and yeast from 3.0*10±1.9*102 to <10±0.0 CFU/g.
