Je HJ, Kim UI, Koo OK. A comprehensive systematic review and meta-analysis of Listeria monocytogenes prevalence in food products in South Korea. Int J Food Microbiol 2024; 415:110655. [PMID: 38430686 DOI: 10.1016/j.ijfoodmicro.2024.110655] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/05/2023] [Revised: 02/23/2024] [Accepted: 02/27/2024] [Indexed: 03/05/2024]
Abstract
Listeria monocytogenes is a foodborne pathogen that can cause deadly severe listeriosis. While systematic review and meta-analysis are powerful tools for comprehensive analysis by pooling every related study, these approaches to L.monocytogenes contamination food have yet to be studied in South Korea. We aimed to identify high-risk L.monocytogenes foods in South Korea through a prevalence survey of retail food products for the first time. A total of 13,684 samples of 59 articles were used for meta-analysis through the systematic review, and the results were synthesized using a random-effects model considering the heterogeneity. The overall pooled prevalence was 2.26 % (95 % CI: 1.44-3.52 %). Among nine food categories, meat exhibited the highest prevalence at 8.32 % (95 % CI: 4.42-12.14 %) after sample size restriction. Specifically, a post-hoc sensitivity analysis was conducted to identify the prevalence difference among subgroups and the source of heterogeneity. Intriguingly, the analysis revealed chicken as the primary contributor to the elevated prevalence of L.monocytogenes, a key factor deriving the observed heterogeneity. This study carries significant implications for public health and food safety in Korea. Furthermore, knowledge of differences in prevalence levels in various foods will be able to be used as a predictive guideline for foodborne outbreaks.

Abstract
This study was performed to evaluate the microbial and temperature changes of boxed beef during transport and distribution under vacuum and modified atmosphere packaging (MAP), and to compare between excision and swab sampling for 15 days. The top round and striploin (quality grade 1) from Hanwoo steers at 2 days post-slaughter were obtained from a local meat processing plants and chilled at 4 ± 2°C in a cold room. The boxes were transported under refrigeration (4 ± 2°C) to the laboratory within half an hour. Vacuum and MAP packs were subsequently taken out from cool boxes, and microbiological examinations were carried out at 0, 6, 12, and 24 h of storage time. MAP was more effective than vacuum packaging for the inhibition of total aerobic, lactic acid bacteria and Pseudomonas (p < 0.05). Microbial loads of swab methods were slightly lower than those of excision ones (p < 0.05). The results of this study could be utilized by meat consumers in future studies as well as by manufacturers to determine the ideal storage conditions for cool boxed meat, thus ensuring reduced economic losses due to spoilage.

Korean J Food Sci Anim Resour 2018; 38:1237-1245. [PMID: 30675116 PMCID: PMC6335133 DOI: 10.5851/kosfa.2018.e57] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/29/2018] [Revised: 11/14/2018] [Accepted: 11/18/2018] [Indexed: 11/11/2022] Open
Abstract
In this study, the contamination levels of hygienic indicators and foodborne
pathogens in retail meat products were investigated in relation to the various
market factors including processing temperature, processing area, and market
type. Ground beef samples (n=80) were purchased from 40 meat markets and
investigated for microbiological quality. Beefs processed below 20℃ had
significantly lower numbers of total coliforms (TC) than these processed over
20℃ (2.01 vs. 2.79 log CFU/g; p<0.05). Interestingly, separation
of processing area did not affect the contamination levels. Remarkably, the
contamination levels of hygienic indicator differ among market types, indicating
that not only processing condition but distribution structure that is directly
related with storage period could affect the final microbiological loads of the
meat products. In addition, the prevalences of Listeria
monocytogenes (a psychrotroph), Enterococcus
faecium, and Enterococcus faecalis were 7.5%
(6/80), 10.0% (8/80), and 20.0% (16/80), respectively, which is irrelevant to
market factors except meat products from wholesale markets where no L.
monocytogenes were found among 30 samples. The results of this
study indicate that the contamination level of hygiene indicator and foodborne
pathogens in retail beef is more related with processing temperature and storage
period than other environmental factors.

Abstract
Objectives This study aims to assess the bacteriological quality of marketed raw meat with a special emphasis on isolation of Escherichia coli, Salmonella spp., Shigella spp., Vibrio spp., Pseudomonas aeruginosa and Staphylococcus aureus in raw meat marketed in Dharan. Altogether 50 meat samples were collected from local markets of Dharan and transported to the microbiology laboratory at 4 °C. The meat samples were homogenized in a sterile glass homogenizer and the possible pathogens were isolated and identified by conventional microbiological techniques. Results The mean total viable count values were found having a mean count of 8.22 ± 0.14, 8.29 ± 0.17, 7.87 ± 0.18 and 7.92 ± 0.19 in terms of log10 CFU/g ± Standard Error for chicken, pork, buffalo, and goat meat respectively. Coliforms were found in 84% samples, S. aureus was found in 68% samples, Salmonella spp. in 34% samples, Shigella spp. in 6% samples, Vibrio spp. in only 3 samples and P. aeruginosa was isolated from 40% sample. Higher microbial load and presence of intestinal commensals E. coli, Salmonella spp., Shigella spp., Vibrio spp indicates that meat might be contaminated by the visceral content and consumers are at risk of getting a foodborne disease when eaten raw.

Prevalence and toxin type of Clostridium perfringens in beef from four different types of meat markets in Seoul, Korea. Food Sci Biotechnol 2017; 26:545-548. [PMID: 30263577 PMCID: PMC6049433 DOI: 10.1007/s10068-017-0075-5] [Citation(s) in RCA: 9] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/28/2016] [Revised: 01/20/2017] [Accepted: 01/20/2017] [Indexed: 10/19/2022] Open
Abstract
Beef is the primary source of foodborne poisoning caused by Clostridium perfringens. We investigated the prevalence of C. perfringens in retail beef from four different types of meat markets in Seoul using a standard culture method and real-time PCR assay. From June to September 2015, 82 beef samples were collected from 6 department stores (n=12), 14 butcher shops (n=28), 16 traditional markets (n=32), and 5 supermarkets (n=10). The culture method and real-time PCR assay revealed that 4 (4.88%) and 10 (12.20%) samples were positive for C. perfringens, respectively. The beef purchased from the department store showed the highest prevalence (16.67%), followed by the traditional market (3.12%), butcher shop (3.57%), and supermarket (0%) (p>0.05). All isolates were type A and negative for the enterotoxin gene. In conclusion, the real-time PCR assay used in this study could be useful for rapid detection and screening of C. perfringens in beef.
