Effects of Good Manufacturing Practice (GMP) on Sealed Drinking Water Factories in Rayong Province

Abstract

The objectives of this descriptive research were to study the knowledge, attitude, and outcome and Good Manufacturing Practice (GMP) in drinking water manufacturing.  Data were collected from all 70 registered manufacturers of sealed drinking water between 1 September and 31 October 2008 and were analyzed using descriptive statistic, such as percentage, mean and standard deviation.  The questionaire was used as a tool that was composed of general data, knowledge and attitude measurement and workplace evaluation form.

It was found that 61.4 percent of the entrepreneurs were knowledgeable about GMP drinking water manufacturing while equal proportion of 40 percent of them had good or fair attitude. Only 78.6 percent of the workplaces failed to follow the GMP.  Most of substandard conditions were detected in bottling section (62.0%) and in processing areas (14.3%).

Based on 60.0 percent of passing grade on GMP, most of the manufacturing plants passed in almost all categories (68.8%) but one-recording (42.7%).  Training of operators may be required particularly for those without university education.  Also attention should be paid to those not qualified to register legally as industry and operated less than 5 years or over 11 years and focusing on recording, reporting, bottling and processing.
