Microbial assessment of kitchen dishcloths for the presence of targeted bacteria
Journal Title: Environmental Health Engineering and Management Journal - Year 2025, Vol 12, Issue 1
Abstract
Background: Dishcloths play a crucial role in keeping kitchen surfaces hygienically clean; however, they can also spread pathogens from spilled food to hands and other food items. The present study aimed to investigate the microbial load of dishcloths, with a specific focus on pathogenic bacterial contaminants they potentially harbor. Methods: A total of 50 samples were collected from households in the Hyderabad district of Pakistan. Specific media were used to isolate the bacteria. Additionally, the hygiene of dishcloths was evaluated visually, and questionnaires were administered to gather information on the various purposes of dishcloths, the source of water used, and the socio-demographic details of the participants. Results: The results showed that 42 out of 50 dishcloths had poor hygiene conditions. Almost half of the participants (48%) used the dishcloth for cleaning their kitchen surfaces, and only 18% of the participants washed it daily. Microbial assessment of dishcloths revealed widespread pathogenic contamination. Nearly all dishcloths tested positive for various microorganisms; 98% for total coliforms, 84% for Staphylococcus aureus, 82% for Vibrio cholerae, 74% for Shigella, 54% for Salmonella, 54% for Escherichia coli, and 26% for Pseudomonas aeruginosa. No significant relationship was found between the frequency of dishcloth washing and the presence of total coliforms, as determined by the Kruskal- Wallis H-test (H = 2.981, P = 0.561). Conclusion: The high level of microbial contamination in dishcloths can potentially transmit pathogens and cause infections. Implementing effective disinfection methods, such as boiling or regular washing with detergent, is essential to prevent pathogen transmission.
