Background and Aim: The main principle of ensuring the health and pharmaceutical medicine.In accordance with its combination of drugs can be the perfect environment for growth of microorganisms.The aim this research was to identify microorganisms in raw materials, water and environment, and other antimicrobial disinfectant effect of in eliminating them.

Materials and Methods: In this descriptive study, 5 step 52 series production of gastric juice manufacturing factory sampling was performed before and after sterilization.Plate count method was used to measure microorganisms. If there is contamination of the culture media and biochemical tests for the detection of specific microorganisms such as Staphylococcus aureus, E.coli, Pseudomonas aeruginosa, Aspergillus niger and Salmonella spp. were used.

Results: The result showed that Micrococcus in 3 cases, 2 cases of Serratia spp., Bacillus subtilis, in two instances, in one instance, Salmonella spp., S. aureus and A.niger in one sample were present in one sample.

Conclusions: The experiments showed that the infected samples 19.2% are. 13.5%, which includes microorganisms, non-pathogenic, with over 100 CFU/ml are 5/7% of the sample remained, including microorganisms, virulence such as S. aureus, 1.1%, Salmonella 1.1% the A.niger and 1.1% respectively.
