ObjectivesThe purpose of this study was to assess the microbiological quality of unchlorinated drinking water in Korea, 2010. One hundred and eighty unchlorinated drinking water samples were collected from various sites in Seoul and Gyeonggi province.MethodsTo investigate bacterial presence, the pour plate method was used with cultures grown on selective media for total bacteria, total coliforms, and Staphylococcus spp., respectively.ResultsIn the 180 total bacteria investigation, 72 samples from Seoul and 33 samples from Gyeonggi province were of an unacceptable quality (>102 CFU/mL). Of all the samples tested, total coliforms were detected in 28 samples (15.6%) and Staphylococcus spp. in 12 samples (6.7%). Most of the coliform isolates exhibited high-level resistance to cefazolin (88.2%), cefonicid (64.7%) and ceftazidime (20.6%). In addition, Staphylococcus spp. isolates exhibited high-level resistance to mupirocin (42%). Species of Pseudomonas, Acinetobacter, Cupriavidus, Hafnia, Rahnella, Serratia, and Yersinia were isolated from the water samples.ConclusionsThe results of this study suggest that consumption of unchlorinated drinking water could represent a notable risk to the health of consumers. As such, there is need for continuous monitoring of these water sources and to establish standards.

“…Antimicrobial susceptibility of S. aureus isolated from various food samples to new agents (linezolid and quinupristin-dalfopristin) has been investigated only in several countries. New agents showed good activity against S. aureus isolated from frozen food samples collected in Korea (Baek et al, 2009). White et al (2003) also reported that all S. aureus isolated from commercial broilers in northeastern Georgia were susceptible to linezolid and quinupristin-dalfopristin.…”

“…Antimicrobial resistance pattern of S. aureus to quinolones and new agents has been investigated in S. aureus in various clinical studies (Sader et al, 2001;Jevitt et al, 2003;Madhusudhan et al, 2003;Jorgen et al, 2007;Hidalgo et al, 2008;Jacobs et al, 2009;Japoni et al, 2010), whereas less information has been reported on antimicrobial activity of these agents in food isolates (White et al, 2003;Baek et al, 2009).…”

Staphylococcus aureus is a versatile pathogen of humans and animals that has evolved resistance to all classes of antimicrobials. A total of 293 S. aureus isolates including 71 obtained from human and 222 recovered from food against crucial antimicrobial agents used in human and veterinary practice were examined for the antimicrobial resistance profiles. The in vitro activities of new agents (linezolid and quinupristin-dalfopristin), quinolones (ofloxacin, norfloxacin, levofloxacin, moxifloxacin) and imipenem against the isolates were performed by standard disk diffusion method. The 293 isolates demonstrated very low levels of resistance to imipenem (0.7%), followed by quinupristin-dalfopristin (1.7%) but had the highest activity against linezolid (6.8%) and moxifloxacin (5.5%). Over 9.9% of clinical isolates showed resistance to three or more antimicrobial agents. Only 1.8% of food isolates were multidrug resistant (≥3 antibiotics). The differences between clinical and food isolates in the results of antimicrobial resistance were statistically significant. Besides, comparing the resistance to each antimicrobial agent between the two group isolates, there were statistically significant differences (P<0.05). Because S. aureus has a remarkable propensity to develop or acquire resistance to antimicrobial agents, it is important to continually monitor antimicrobial susceptibilities of isolates from clinical and food sources.

“…Frozen foods do not need any additional additives since microorganisms do not develop when the temperature of the food is beneath −9.5 °C (15 °F), which is adequate in forestalling food deterioration. Most microbes do not increase at frigid temperature and a large number of these microorganisms die because their enzymes do not work appropriately to keep up ordinary cell activities (Baek et al, 2009). Freezing is the prevailing method of preserving high quality in foods.…”

This study seeks to investigate the microbial profile of frozen fish and meat. Forty samples consisting of Scomber scombrus (Titus), Clupea harengus (Shawa) and frozen meat (Chicken, Turkey) were purchased from different retail outlets in Ayobo-Ipaja markets for microbiological analysis. The samples were analysed for the total viable count using standard microbiological procedures. The mean bacterial and fungal counts for Scomber scombrus, Chicken, Clupea harengus and Turkey are 254.70±83.81 CFU/G and 5.50±4.45 CFU/G; 210.10±55.03 CFU/G and 6.80±3.39 CFU/G; 298.20±67.35 CFU/G and 6.10±3.87 CFU/G; 221.30±80.33 CFU/G and 4.30±2.00 CFU/G respectively. Clupea harengus has the highest bacterial count while Scomber scombrus has the lowest bacterial count. Chicken has the highest fungal count while Turkey had the lowest fungal count. The microbial isolates from the frozen food samples include species of S. aureus, E. coli, Salmonella, Micrococcus, Aspergillus, and Penicillium. Escherichia coli were susceptible to all the antibiotics while Salmonella sp., Staphylococcus aureus, and Micrococcus were resistance to Augmentin, Gentamycin, Tarivid, and susceptible to Sparfloxacin and Chloramphenicol. Although freezing retard pathogens multiplication, post-harvest contaminants can multiply during thawing to a level that can have a major impact on the quality of the final consumer product. It is advised that frozen foods must be properly cooked before consumption and effective hazard analysis and critical control point implemented.
