“…The total aerobic plate count of samples obtained from various stages of production can be used as a general indicator of sanitation. Microbial surveys of various foods reveal that products handled under good sanitary conditions usually have significantly lower microbial counts than products produced in food plants operating under poor sanitary conditions (Banwart 1989). …”

This study was conducted to evaluate the microbial quality of street‐vended foods in Korea. The microbiological contamination levels of aerobic mesophilic bacteria ranged from 0 to 7.43 log cfu/g with a mean value of 4.71 ± 1.53 log cfu/g, while the level of total coliforms ranged from 0 to 6.86 log cfu/g with a mean value of 3.24 ± 1.40 log cfu/g. Staphylococcus aureus (SA) and Escherichia coli (EC) were detected in 9% (mean value: 3.75 ± 0.56 log cfu/g) and 3% (mean value: 2.33 ± 0.90 log cfu/g) of 326 examined samples, respectively. Vibrio parahaemolyticus, Salmonella spp. and Listeria monocytogenes were not detected. More than 50% of the isolated SA were found to be enterotoxin producers and these organisms primarily possessed type A toxin genes. Conversely, verocytotoxin‐producing EC were not detected. Taken together, these results indicate that consumption of street‐vended foods may pose a risk of foodborne disease and that good hygienic practices should be required to ensure public health. PRACTICAL APPLICATIONS Accurate and up‐to‐date data for microbiological contamination of ready‐to‐eat foods are necessary for consumer protection to improve sanitary conditions in food processing plants in Korea. Known contamination levels can be used by administrators to establish national regulations for the control of foodborne diseases.

These results indicate that sanitary standards and specifications for convenience foods are necessary in Korea.…”

Levels of total aerobic plate counts (APC), coliforms and various pathogens in convenient foods including ready‐to‐eat foods (RTE), ready‐to‐cook foods (RTC) and fresh‐cut produce (FCP) in Korea were investigated. A total of 244 samples comprising 145 samples of RTE, 39 samples of RTC and 60 samples of FCP were purchased from hyper chain stores located in six different provinces. APC levels of RTE showed a relatively wide range of 1.9–7.8 log10cfu/g, while APC levels of RTC and FCP were relatively high at 6.3–8.1 log10cfu/g. Coliform contamination was detected in approximately 50% of the samples at levels up to 5 log10cfu/g. Escherichia coli was most frequently detected in convenient foods, and followed by Staphylococcus aureus. Salmonella spp. and Listeria monocytogenes were detected in only one sample and Vibrio parahaemolyticus was not detected in any sample. These results show that convenient foods in Korea can be contaminated by various pathogenic bacteria. Therefore, precautionary measures are necessary for consumer protection including improving sanitary conditions in the processing plants for RTE, RTC and FCP products in Korea. PRACTICAL APPLICATIONS Accurate and up‐to‐date data for microbiological contamination of convenient foods including ready‐to‐eat foods, ready‐to‐cook foods and fresh‐cut produce are necessary for consumer protection to improve sanitary conditions in food processing plants in Korea. Known contamination levels of indicator organism and/or pathogenic bacteria can be used by administrators to establish national regulations for control of foodborne diseases.
