This study aims to develop preventive measures to decrease microbial contamination in the manufacturing of the ice tube by using principles of hazard analysis and critical control points.
An analysis of a sample of water and sacks of ice collected during normal production processes of plants. Microbial water and ice over a standard DFA Thailand in addition to the implementation of measures, develop good manufacturing practices. In need of cleaning the surface of all the equipment and personal hygiene, such as the worker directly contact ice tubes also must perform strictly.
