Background and Aim: Chicken meat can be contaminated by microorganisms anywhere in the supply chain, from farm to market, and these microorganisms can be transmitted to humans through direct contact, contact with the environment, and food consumption. The microbial contamination has a serious impact on public health. This study aimed to analyze the microbial contamination of chicken meat sampled from local markets in Surabaya, East Java, Indonesia. Materials and Methods: A total of 60 samples of fresh chicken meat obtained from 10 traditional markets (six samples per market) were examined for the presence of bacteria. Staphylococcus aureus, Salmonella spp., and Escherichia coli were identified using Gram staining, culturing, and biochemical tests. The most probable number (MPN) method was used to identify E. coli. Results: Most chicken meat samples were positive for S. aureus (58.3%), Salmonella spp. (48.3%), and E. coli (40%). The samples were considered positive for E. coli if the MPN value was higher than 1×101 CFU/g. Conclusion: High microbial contamination was found in all the chicken meat sampled from local markets in Surabaya. Such contamination can lead to foodborne diseases so, proper hygiene and sanitation standards should be followed from slaughterhouses to the end-users.

In Bangladesh, food sold at local markets are usually not kept under hygienic conditions leading to contamination with different microorganisms and deterioration of food quality. This study was carried out to examine the microbial quality of prawns sold at local markets. Prawn samples collected from different markets were assessed for their bacteriological quality using the multiple tube fermentation technique to determine coliform count using the most probable number method in Brilliant Green Lactose Broth (BGLB) media. Positive tubes of the presumptive test were further cultured on Eosine Methylene Blue(EMB) and Mac Conkey agar media. The organisms isolated were further characterized using biochemical tests. Out of the 65 samples, 47 (72.3%) showed positive results in all 3 tubes of dilution series using inoculum quantities of 1, 0.1 and 0.01 g.Among 65 samples 57 samples that contained at least one positive in each dilution series were further re-identified with biochemical tests.This study showed 56.14%isolates were Escherichia coli which conformed to expected biochemical reactions, formed round, small,elevated colonies with pink pigmentation on Mac Conkey agar media and round, small colonies with metallic green sheen pigmentation on EMB agar media. Other bacteria which presumptively appeared to be enterics and were isolated from BGLB were identified as Klebsiellapneumoniae(29.82%),Staphylococcus aureus(8.7%), Enterobacter aeroginosa(3.5%) and Salmonellatyphimurium (1.75%).Presumptive identification of E. coli in prawn in order to determine fecal contamination was able to identify ¾ of BGLB tubes with actual occurrence of E. coli. From this study it has been found that 97.14% bacteria were sensitive to Co-Trimoxazole, compared to other antibiotics used in this test whereas only 37.14% bacteria were sensitive to nitrofurantoin. This study also highlighted the fact that prawns act as a major source of E. coli which indicates possible fecal contamination as well as presence of potentially pathogenic E. coli and these bacteria are resistant at a great percentage to almost all of these antibiotics used in this study. Prawns must therefore be cooked adequately before consumption. Bangladesh J Microbiol, Volume 35 Number 1 June 2018, pp 13-16

ABSTRACT Although wildlife intrusion and untreated manure have been associated with microbial contamination of produce, relatively few studies have examined the survival of Escherichia coli on produce under field conditions following contamination (e.g., via splash from wildlife feces). This experimental study was performed to estimate the die-off rate of E. coli on preharvest lettuce following contamination with a fecal slurry. During August 2015, field-grown lettuce was inoculated via pipette with a fecal slurry that was spiked with a three-strain cocktail of rifampin-resistant nonpathogenic E. coli. Ten lettuce heads were harvested at each of 13 time points following inoculation (0, 2.5, 5, and 24 h after inoculation and every 24 h thereafter until day 10). The most probable number (MPN) of E. coli on each lettuce head was determined, and die-off rates were estimated. The relationship between sample time and the log MPN of E. coli per head was modeled using a segmented linear model. This model had a breakpoint at 106 h (95% confidence interval = 69, 142 h) after inoculation, with a daily decrease of 0.70 and 0.19 log MPN for 0 to 106 h and 106 to 240 h following inoculation, respectively. These findings are consistent with die-off rates obtained in similar studies that assessed E. coli survival on produce following irrigation. Overall, these findings provide die-off rates for E. coli on lettuce that can be used in future quantitative risk assessments.

Majority of the population of Bangladesh depend on tap or surface water as their source of water supply. This study was carried out to examine the microbial quality of both water and soil collected from different places using the multiple tube fermentation technique to determine coliform count by the most probable number (MPN) method in brilliant green lactose broth (BGLB) media.Inoculum from positive tubes of the presumptive test were further transferred on eosinemethylene blue (EMB) and MacConkey agar.The organisms isolated were further characterized using biochemical tests. Out of 93 water samples, 30 (32.26%) indicated the presence of lactose fermenter and gas producer in all 3 tubes of dilution series using inoculum quantities of 1.0, 0.1 and 0.01 ml, whereas out of 85 soil samples, 45 (52.94%) showed acid and gas production in all 3 tubes of dilution series.Among 85 soil samples, 40 samples that contained at least one positive in each dilution series and among 93 water samples, 31 samples that contained at least one positive in each dilution series were further re-identified with biochemical tests.This study showed 30.59% soil isolates and 26.88% water isolates were Escherichia coli which highlighted the fact that both water and soil act as a major reservoir of E.coli, which indicates possible fecal contamination as well as presence of potentially pathogenic E. coli.

ABSTRACT: Brazil is the largest exporter of beef of the world and Mato Grosso State is the highest beef producer in this country. To maintain product competitiveness and market expansion, sanitary hygienic control of the entire process is indispensable to ensure the attainment of harmless beef and quality. The objective of this study was to evaluate the hygienic sanitary conditions of vacuum-packed beef produced by establishments qualified for export in the state of Mato Grosso, Brazil. A total of 60 samples were submitted to coliforms counts at 35°C and at 45°C and E. coli. The mean contamination by at 35°C and coliforms at 45°C were 3,1 x 102MPN/g and 7.7MPN/g respectively. The presence of E. coli was verified in five samples, representing an occurrence of 8.3% (5/60), and Salmonella spp. in 5% (03/60) of the analyzed samples. The MPN (Most Probable Number) average of coliforms at 35°C and 45°C are in accordance to national and international legislation; however, the presence of Samonella spp., E. coli in some sample indicates a low risk of occurrence of salmonellosis and colibacillosis transmitted by the evaluated beef. However, transmission risk of these diseases cannot be ruled out, since the presence of E. coli does not depend on the amount of coliforms and national legal standards established for the group of thermotolerant coliforms.

The focus of this study was to evaluate the microbial quality of Spanish potato omelette and cooked meat samples including pork loin, chicken croquettes, long pork sausage, chicken breast, and meatballs from University restaurants. Microbiological analyses of Spanish potato omelette and cooked meat samples resulted in aerobic plate counts from <1.00 to 2.90 and from <1.00 to 6.04 log10 CFU g−1, respectively. Total coliforms ranged from <3 to 43 most probable number (MPN) g−1 and from <3 to >2,400 MPN g−1 for Spanish potato omelette and meat products, respectively. Escherichia coli, coagulase-positive staphylococci, and Lancefield group-D streptococci were detected in 1.7%, 3.5%, and 12.9% of Spanish potato omelette samples, respectively. For cooked meat samples, 8.8%, 7.6%, and 24.6% contained E. coli, coagulase-positive staphylococci, and Lancefield group-D streptococci, respectively. E. coli O157:H7, Salmonella spp., and Shigella spp. were not detected. Klebsiella pneumoniae, Klebsiella oxytoca, Citrobacter freundii, Enterobacter cloacae, and Serratia spp. were isolated from Spanish potato omelette samples. For cooked meat samples, C. freundii, E. cloacae, and Aeromonas hydrophila were detected. The results suggest that some handling practices should require more attention, and as a consequence, a hazard analysis and critical control point program should be developed and implemented.

Foodborne pathogens are serious public healthproblems that greatly affect the cost of food production and healthcare while poultry are often associated with foodborne disease outbreaks. This study aimed at investigating the occurrence and distribution of bacterial pathogens associated with chicken meats sold around Bayero University, Kano old site. A total of twenty (20) meat samples comprised of 10 frozen and ten freshly slaughtered chicken were purchased from different selling outlets around the study area. The samples were processed using standard cultural and biochemical procedures. The results of the study showed the mean aerobic mesophilic bacterial count of 5.93 x 106 CFU/g and 3.12 x 106  CFU/g for frozen and freshly slaughtered chicken meat samples respectively. The coliform counts were 420.1 and 347.7 CFU/100g for frozen and freshly slaughtered chicken meat samples respectively. The distribution of different bacterial species revealed E. coli (26.0%), Klebsiella spp (4.0%), Salmonella spp (19.5%), Campylobacter spp. (14.6%) and Staphylococcus aureus (30%) in frozen chicken meat samples while freshly slaughtered chicken meat samples revealed E. coli (21.0%), Klebsiella spp (8.9%), Salmonella spp (30%), Campylobacter spp. (15.0%) and Staphylococcus aureus (24.0%). This showed that frozen chicken meats were more contaminated than freshly slaughtered chicken meats which might be associated with poor handling and storage conditions.

Foodborne diseases are diseases transmitted through contaminated food and are one of the main public health problems. The bacteria that usually contaminates chicken meat is Escherichia coli. E. coli contamination in chicken meat can affect consumer health. Chicken meat processing and market conditions affect the level of bacteria contamination. This study aims to measure the contamination of E. coli bacteria in chicken meat in Surabaya's markets. The method which used to count and estimate the number of E. coli bacteria found in chicken meat in this study was Most Probable Number (MPN). The results showed 20 samples (33.3%) from 60 samples gave negative results. This indicated that only 20 samples of chicken meat were safe for consumption because the MPN value is <1 × 101 CFU/g while the remaining 40 samples (66.7%) were not safe for consumption because the MPN value is> 1 × 101 CFU/g. The standard of SNI 3924: 2009 concerning the minimum requirement for the amount of E. coli contamination in chicken meat is 1×101 CFU/g so that the contamination of E. coli which found in chicken meat in Surabaya was high.

Abstract The Bacteriological Analytical Manual (BAM) Salmonella pre-enrichment broth [lactose (LAC) broth], buffered peptone water, and universal pre-enrichment (UP) broth were compared with TA10 broth, developed in our laboratory, for recovery of heat- and freeze-injured Salmonella (55°C for 2–20 min and –20°C for 2 months, respectively) from beef. Beef samples were contaminated with single Salmonella serovars, and contamination levels of 0.44 to &lt;0.001 most probable number (MPN)/g and 0.74 to 0.14 MPN/g were used for heat- and freezing-induced injury studies, respectively. Twenty test portions (25 g) of the contaminated beef were pre-enriched in each broth, and the BAM Salmonella culture method was used thereafter. There was a significant difference (χ2 = 7.73) in recovery of heat-injured Salmonella between TA10 broth and LAC broth, 189 (67.5%) versus 156 (55.7%) positive samples, respectively, determined by plating onto selective agars and identification by biochemical tests. For the recovery of freeze-injured Salmonella, there was a significant difference (χ2 = 24.7) between TA10 and LAC broth, 189 (72.7%) versus 133 (51.2%) positive samples, respectively. TA10 broth was more effective than LAC broth and UP broth for recovery of freeze-injured Salmonella. The results indicate that TA10 broth should be used instead of LAC broth for testing of beef that may be contaminated with heat- and freeze-injured Salmonella spp.
