Abstract
The effectiveness of hand washing while wearing gloves of workers in a frozen food processing plant in Samut Sakhon province was investigated by collecting samples using a swab method and assessing a risk of contamination during a production process, to meet the standards of the Department of Medical Sciences. By examination of microbial contamination in samples from 39 workers before glove washing, the results showed that Escherichia coli was found in one sample, Salmonella spp. was found in two samples and Staphylococcus aureus was found in three samples, but no microbial contamination was found in all samples after globe washing. The total number of microbial colonies in samples before and after glove washing was determined by total plate count method. The results showed that the average numbers of colonies in samples before and after glove washing were 4.23 and 2.17 log CFU/25cm2, respectively. The mean percentage reduction of colony number after glove washing was 94.11. From these results, all test samples showed a low risk of microbial contamination after globe washing and passed the standards of the Department of Medical Sciences.
