Efficiencies of training tool on good manufacturing practices and critical control points of production plants of 20-liter packing size drinking water in Cambodia

Abstract

The major public health problem in Cambodia is inaccessibility of safe drinking water. People therefore must rely on bottled drinking water, especially the 20-liter pack size. Consequently, Cambodian officers must increase their knowledge on production processes and hazard control. In this study, the training material was developed based on the Codex Alimentarius's guideline (CODEX) and related researches. A 2-day lecture attended by 50 participants was conducted. They were pretested for their basic knowledge and post-tested after the lecture. After the lecture, 16 plants were audited by an expert and the trainees. The training tool's efficiency was then evaluated based on performance in the post-test and auditing. Results revealed that post-test scores were significantly higher (p ? 0.05) than those of the pre-test in all parts. Scores 39 out of 73 audits of the trainees were not significantly different from those of the expert. The auditing performance was significantly correlated with posttest score, trainee affiliation, location of the affiliation, and the GMP status of the plant (p ? 0.05). The post-test score and auditing performance indicated that passing score for the post-test should be 60%. The training tool was efficient which could assist the officers in monitoring the quality and safety of drinking water in future.
