Purpose: This study was conducted to estimate the microbiological safety of dishcloths and scourers used in the cafeterias of childcare centers.
Methods: Dishcloths and scourers that were sanitized after use were collected from 89 different facilities for testing. Microbial testing was in accordance with Korean food code.
Results: The mean value of the total aerobic bacteria was 4.1±1.9 log cfu/100 cm2 and 5.1±1.9 log cfu/100 cm2, respectively, in the dishcloths and scourers. The contamination levels of coliform bacteria were 3.2±1.8 log cfu/100 cm2 and 3 .2±1 .7 log c fu/1 00 cm2, respectively, in the dishcloths and scourers. There was no significant difference in the contamination levels of total aerobic bacteria and coliform bacteria. There was not much difference in the contamination levels based on the size and type of childcare centers. Two cases of Bacillus cereus were detected among the 89 dishcloths (2.2%) and 3 cases (3.4%) in the 89 scourers. A single case (1.1%) each of Staphylococcus aureus was detected in the 89 dishcloths and scourers. These results indicate a possibility of food poisoning through the dishcloths and scourers used in the childcare center cafeterias.
Conclusion: Thus, proper sanitation methods for the dishcloths and scourers should be followed and continuous education for cooking staff on hygiene management should be ensured.
