The objective of this study was to examine traditional meat product of the Sivas province, the Sivas kofte with regards to its microbiological quality. The kofte samples sold commercially were examined according to their microbiological qualities (150 pieces cooked kofte samples taken from the most popular 5 restaurants). The samples were analyzed in terms of total mesophilic aerobic bacteria, Enterobacteria, E. coli, coagulase positive S. aureus, Salmonella spp. and psychrophilic bacteria. Ready to serve samples of Sivas kofte were examined and the following results were obtained for total mesophilic aerobic bacteria, Enterobacteria, coagulase positive S. aureus, psychrophilic bacteria, 2.7- 4.9 log10 cfu/g, <10 - 2.1 log10 cfu /g, <10 - 1.9 log10 cfu /g, 1.6- 3.8 log10 cfu /g, respectively. E. coli and Salmonella spp were not determined in any of the samples. As a result, the ready to consume Sivas kofte samples were found to be in accordance with the Turkish Food Codex Cominiquate Microbiological Criteria despite differences in the microbiological quality of the locations in Sivas.

This study aimed to determine the effects of cooling on microbiological quality of lamb carcasses. Total Aerobic Bacteria Count (TABC), Enterobactericeae counts and the presence of Salmonella spp. were investigated in accordance with the Turkish Food Codex Regulation on Microbiological Criteria and European Union Commission Regulation 2073/2005. Sampling was carried out on aseptic conditions from the surface of 25 randomly selected lambs brought to slaughterhouse. The results showed that the mean TABC were 2.24±0.087 log cfu/cm2 before cooling and 2.41±0.061 log cfu/cm2 after cooling (P>0.05). The mean Enterobactericeae count was 0.21±0.11 log cfu/cm2 before cooling and 0.69±0.13 log cfu/cm2 after cooling (P<0.01). Furthermore, Salmonella spp. were determined on 3 carcasses before cooling and one another carcass after cooling. The influence of cooling on categorisation according to the legislations presented that it could potentially improve the numbers of acceptable carcasses for TABC and Salmonella spp. Nevertheless, the results exhibited that the hygiene and cooling stage of the slaughter line must be re-evaluated in terms of HACCP requirements and that corrective measures/actions must be taken.

Sprouted vegetable seeds used as food have been implicated as sources of outbreaks of Salmonella and Escherichia coli O157:H7 infections. We profiled the microbiological quality of sprouts and seeds sold at retail shops in Seoul, Korea. Ninety samples of radish sprouts and mixed sprouts purchased at department stores, supermarkets, and traditional markets and 96 samples of radish, alfalfa, and turnip seeds purchased from online stores were analyzed to determine the number of total aerobic bacteria (TAB) and molds or yeasts (MY) and the incidence of Salmonella, E. coli O157:H7, and Enterobacter sakazakii. Significantly higher numbers of TAB (7.52 log CFU/g) and MY (7.36 log CFU/g) were present on mixed sprouts than on radish sprouts (6.97 and 6.50 CFU/g, respectively). Populations of TAB and MY on the sprouts were not significantly affected by location of purchase. Radish seeds contained TAB and MY populations of 4.08 and 2.42 log CFU/g, respectively, whereas populations of TAB were only 2.54 to 2.84 log CFU/g and populations of MY were 0.82 to 1.69 log CFU/g on alfalfa and turnip seeds, respectively. Salmonella and E. coli O157:H7 were not detected on any of the sprout and seed samples tested. E. sakazakii was not found on seeds, but 13.3% of the mixed sprout samples contained this potentially pathogenic bacterium.

This study was carried out to assess the microbiological status of three hot meals served in eight selected school canteens of Mauritius, with two schools randomly selected from each of the four school zones of the island. Three individual samples of farata, panini, or fried noodles were collected at each school during two independent visits. The three individual samples of each food type collected during each visit were then pooled before being subjected to microbiological analyses. A total of 48 composite samples were analyzed. The parameters tested were Total Viable Count (TVC), Escherichia coli, Salmonella spp., Clostridium perfringens, Staphylococcus aureus, and Listeria spp. The microbiological analyses revealed that paninis were deemed as generally acceptable with TVC falling in the range of 3.0-5.7 Log CFU/g and undetectable levels of S. aureus and E. coli. In contrast, fried noodles and faratas harboured a moderately high level of TVC (4.4-6.7 Log CFU/g) and objectionably high levels S. aureus (3.1 to 5.0 Log CFU/g) and E. coli (3.1-5.1 Log CFU/g) for seven out of the eight schools.

O queijo Minas frescal é um dos mais populares do Brasil, porém o alto teor de umidade associado ao métodode processamento, muitas vezes artesanal, e de armazenamento desse produto o tornam muito perecível.Este trabalho teve como objetivo avaliar e comparar a qualidade microbiológica de queijo Minas frescalcomercializado na cidade de Curitiba (PR) nos anos de 1999 e 2009, verificando a evolução na qualidadehigiênico-sanitária desse produto no período de 10 anos. Foram analisadas 11 marcas comerciais de queijo Minas frescal disponíveis no comércio varejista da cidade de Curitiba, sendo amostradas cinco unidades de cada marca, totalizando 55 amostras. Os queijos foram submetidos à pesquisa de Salmonella spp., contagem de coliformes totais e Escherichia coli, contagem de Staphylococcus coagulase positiva e contagem de aeróbios mesófilos, com resultados expressos em UFC/g. Das 55 amostras de queijo, 41,82% e 78,18% apresentaram contagem de E. coli e de coliformes totais acima do limite permitido, respectivamente. Somente uma amostra (1,82%) do total avaliado mostrou-se em desacordo com os padrões para S. coagulase positiva e uma para Salmonella spp. Ambas as amostras foram adquiridas em 2009. Todas as amostras avaliadas em 2009 apresentaram elevada contagem de aeróbios mesófilos, revelando alta carga microbiana. Comparativamente, os queijos avaliados em 1999 mostraram qualidade microbiológica superior aos queijos avaliados em 2009 (p < 0,05). Destes, 100% apresentaram no mínimo um parâmetro microbiológico em desacordo com a legislação vigente, indicando que a qualidade dos queijos Minas frescal avaliados em 2009 apresentou-se inferior a dos queijos avaliados em 1999.

Poor Management

Background and Aim: Pre-slaughter management and slaughter operations are considered critical factors for animal welfare and meat quality. Previous studies have found poor animal welfare management at municipal slaughterhouses in Ecuador, and little is known about how this affects the microbiological quality of the meat. Therefore, the aim of the study was to analyze the association of the microbiological quality of beef carcasses and animal welfare indicators in a municipal slaughterhouse in Ecuador. Materials and Methods: Data for 6 months were collected from a municipal slaughterhouse in Ecuador. Five trained researchers were strategically located along the slaughter process. A total of 351 animals were observed with regard to welfare indicators, and their carcasses were sampled to evaluate microbiological quality. Antemortem (slipping, falling, and vocalization) and postmortem animal welfare indicators (bleed interval, pH, temperature, and bruises) were measured. To determine the total aerobic bacteria (TAB) and Escherichia coli counts and the presence of Salmonella spp., we collected samples by swabbing four different points of each carcass. The association between microbiological quality and animal welfare indicators was studied using univariate and multivariate logistic regressions. Results: The mean TAB count was 5.3 log CFU/cm2, and the mean total count of E. coli was 2.4 log CFU/cm2. Salmonella spp. were isolated in 3.1% of the carcasses. An electric goad was used in all animals, 19.1% slipped at least once, and 19.9% vocalized. The mean pH of the carcasses was 7.2, and 79.2% of carcasses had bruises. Multivariate analysis showed that Salmonella spp. and the TAB count were associated with pH and the number of bruises (p = 0.01 in both cases). Conclusion: Although there was non-significant association between the majority of animal welfare indicators and microbiological quality, the poor management affecting animal welfare and carcass hygiene are worrisome.

Cooking Temperature

Clostridioides difficile reservoirs other than humans are becoming increasingly recognized, and the occurrence of the pathogen in shellfish raises concern because spores can survive cooking temperature and edible bivalve mollusks are often consumed raw or poorly cooked. This study was conducted to determine the occurrence of pathogenic C. difficile in retail bivalve mollusks. The microbiological quality of samples was also checked through the isolation of Salmonella spp. and Escherichia coli. We analyzed 129 mollusk samples from different fishmongers and grocery stores in Murcia. C. difficile was isolated from 8.53% (11/129) of the mollusks investigated. Four C. difficile isolates harbored genes for the production of toxin A and B. Salmonella spp . were not isolated from any sample and E. coli was isolated from 1.55% (2/129) of the samples, in both cases in accordance with the current legal requirements for consumption. Our findings indicate that the intake of raw or poorly cooked contaminated bivalve mollusks could be a potential source of C. difficile, leading to a risk for human health.

&nbsp;Fresh and frozen seafood products (fish, shellfish, crustaceans, molluscs) in wide use in Croatia and typical of the Mediterranean diet, were examined for the presence of microbiological contamination through the winter and summer seasons. Total bacterial counts of aerobic mesophilic bacteria (AB), aerobic psychrophilic bacteria (AP), Salmonella spp., Enterobacteriaceae, Escherichia coli, Staphylococcus aureus, sulphite-reducing clostridia (SRC), Listeria monocytogenes, Vibrio cholerae and V. parahaemolyticus were measured. The microbiological quality of individual samples varied widely between animal species and also between winter/summer seasons regarding total counts of aerobic mesophilic and psychrophilic bacteria. The poorest quality was for (both summer and winter) fish samples, where 66.6 % of fresh and frozen fish were found unacceptable by Croatian standards. The overall prevalence of V. parahaemolyticus was 5%. Its recovery rate was higher in fresh/frozen shellfish in both seasons than in other specimens or other storage/season conditions. Fresh crustaceans sampled in winter demonstrated significantly higher aerobic mesophilic counts than frozen ones. Unacceptable Enterobacteriaceae levels were obtained in 40% of the fresh fish summer samples. The results of this survey constitute an indicator of bacteriological contamination of a variety of seafood. The findings could serve as a basis for future testing of seafood, and possibly as a template for developing a regional/Mediterranean testing scheme on the microbial contamination of seafood in order to establish data with comparative epidemiological and statistical values.

The microbiological quality of 745 conventionally processed and 745 reprocessed broiler carcasses was determined. Carcasses were taken from the processing line prior to entering the chiller in five commercial processing plants. Each plant was sampled twice during the winter, spring, and summer. Analyses included aerobic bacteria, Enterobacteriaceae, and Escherichia coli counts plus qualitative Salmonella (SAL) prevalence. Differences between overall mean log10 counts for aerobic bacteria, Enterobacteriaceae, and E. coli were not significant. The prevalence of SAL detected on conventionally processed and reprocessed carcasses also was not significantly different. Some variation was observed in microbiological quality of carcasses among processing plants. Although the SAL prevalence appeared to decline from winter to summer replications, no significant trend could be demonstrated. Continuation of the practice of reprocessing carcasses appears justified.

Potential Link

The potential transfer of human pathogenic bacteria present in irrigation water onto fresh produce was investigated, because surface water sources used for irrigation purposes in South Africa have increasingly been reported to be contaminated with enteric bacterial pathogens. A microbiological analysis was performed of a selected river in Limpopo Province, South Africa, that is often contaminated with raw sewage from municipal sewage works and overhead irrigated onions produced on a commercial farm. Counts of Escherichia coli, coliforms, aerobic bacteria, fungi, and yeasts and the prevalence of E. coli O157:H7, Salmonella, and Listeria monocytogenes were determined. Identities of bacterial isolates from irrigation water and onions were confirmed using matrix-assisted laser desorption ionization–time of flight mass spectrometry, PCR, and biochemical tests. To establish a potential link between the microbiological quality of the irrigation source and the onions, the E. coli isolates from both were subjected to antibiotic resistance, virulence gene, and enterobacterial repetitive intergenic consensus PCR analyses. River water E. coli counts exceeded South African Department of Water Affairs and World Health Organization irrigation water guidelines. Counts of aerobic bacteria, coliforms, fungi, and yeasts of onions from the market were acceptable according to Department of Health Directorate, Food Control, South Africa, microbiological guidelines for ready-to-eat fresh fruits and vegetables. E. coli O157:H7, Salmonella, and L. monocytogenes were not detected in onions, whereas only Salmonella was detected in 22% of water samples. Matrix-assisted laser desorption ionization–time of flight mass spectrometry and PCR identification of E. coli isolates from water and onions correlated. Of the 45 E. coli isolates from water and onions, 42.2% were resistant to multiple antibiotics. Virulence genes eae, stx1, and stx2 were detected in 2.2, 6.6, and 2.2% of the E. coli isolates, respectively. Phenotypic (antimicrobial) and genotypic (virulence gene prevalence, DNA fingerprinting) analyses showed a link between river, dam, irrigation pivot point, and onion E. coli isolates.
