“…By analogy with bacteriological dishcloth protocols (Koo et al, 2013;Lee, 2010), cotton dishcloths were cut into 6 cm × 6 cm segments (n = 30), autoclaved at 110°C for 20 min and stored in sterile Petri dishes. Three milliliters of PAS was added to the sterile dishcloths, followed by spiking with 2 ml of the final concentration (see above) of the protozoan cultures.…”

In the present study, the occurrence of free-living protozoa (FLP) and foodborne bacterial pathogens on dishcloths was investigated. Dishcloths form a potentially important source of cross-contamination with FLP and foodborne pathogens in food-related environments. First various protocols for recovering and quantifying FLP from dishcloths were assessed. The stomacher technique is recommended to recover flagellates and amoebae from dishcloths. Ciliates, however, were more efficiently recovered using centrifugation. For enumeration of freeliving protozoa on dishcloths, the Most Probable Number method is a convenient method. Enrichment was used to assess FLP diversity on dishcloths (n = 38). FLP were found on 89% of the examined dishcloths; 100% of these tested positive for amoebae, 71% for flagellates and 47% for ciliates. Diversity was dominated by amoebae: vahlkampfiids, vannellids, Acanthamoeba spp., Hyperamoeba sp. and Vermamoeba vermiformis were most common. The ciliate genus Colpoda was especially abundant on dishcloths while heterotrophic nanoflagellates mainly belonged to the genus Bodo, the glissomonads and cercomonads. The total number of FLP in used dishcloths ranged from 10 to 10 4 MPN/cm 2 . Flagellates were the most abundant group, and ciliates the least abundant. Detergent use was identified as a prime determinant of FLP concentrations on used dishcloths. Bacterial load on dishcloths was high, with a mean total of aerobic bacteria of 7.47 log 10 cfu/cm 2 . Escherichia coli was detected in 68% (26/38) of the used dishcloths, with concentrations up to 4 log 10 cfu/cm 2 . Foodborne pathogens including Staphylococcus aureus (19/38), Arcobacter butzleri (5/38) and Salmonella enterica subsp. enterica ser. Halle (1/38) were also present. This study showed for the first time that FLP, including some opportunistic pathogens, are a common and diverse group on dishcloths. Moreover, important foodborne pathogens are also regularly recovered. This simultaneous occurrence makes dishcloths a potential risk factor for cross-contamination and a microbial niche for bacteria-FLP interactions.

“…Proper cloth materials to wipe food utensils are important because bacteria can cross contaminate from a dirty surface to a clean one (Koo et al 2013). Furthermore, approximately more than 90% of respondents identified the correct answers for proper cleaning and storage of food utensils.…”

“…The ATP bioluminescence assay is a widely used method to monitor food processing surfaces in the food industry (Davidson, Griffith, Peters, & Fielding, 1999;Koo et al, 2013). The results are available within a few minutes but the assay detects both microorganisms and food residues, which can lead to inconsistent correlation with the level of bacterial contamination (Aycicek, Oguz, & Karci, 2006;Koo et al, 2013).…”
