Contamination of Salmonella was assessed in duck and chicken meat collected from supermarkets, traditional markets, internet shopping malls, and wholesale markets in Jeonlado, South Korea, in 2013. Salmonella contamination was found in 51.3% of duck meat samples and 3.7% of chicken meat samples. Salmonella contamination of duck meat samples differed by meat type, i.e., 69.8% of samples of whole ducks and 33.9% of samples of duck pieces. Six serotypes were identified from 64 Salmonella isolates in duck meat: Salmonella Typhimurium (37.5%), Salmonella Enteritidis (21.8%), Salmonella Stanley (3.1%), Salmonella Regent (1.6%), Salmonella Winterthur (3.1%), and Salmonella Westhampton (1.6%). All isolates were resistant to one or more antibiotics. Resistance to sulfisoxazole was most common (93.8% of isolates), followed by resistance to nalidixic acid (59.4%), ceftazidime (26.6%), and ampicillin (26.6%). To our knowledge, this study is the first to report Salmonella contamination in duck meat from Korea. Duck meat should be considered an important source of foodborne pathogens.

The objective of this study was to identify the phylogenetic analysis and antibiotic resistance of Listeria monocytogenes contaminating chicken meat in Surabaya. 60 chicken meat samples were collected from supermarkets, mobile vendors, and traditional markets in Surabaya. A selective medium is used for isolation and identification of Listeria monocytogenes by chopping 25 grams of the chicken meat and to put it into the sterilized Erlenmeyer flasks. Some methods were used for the identification procedures, such as biochemical and morphological tests, antibiotic resistance test, PCR, and sequencing; also a phylogenetic analysis was conducted by a neighbor-joining analysis using Genetix Mac ver 8.0 with hlyA genes of Listeria monocytogenes recorded in GenBank, such as Lineage I (KC808543), Lineage II (AY229462, AY229346, AY229499, and AY229404), Lineage III (KJ504139, HQ686043, KJ504116, and DQ988349), and Lineage IV (EU840690, EF030606). The result shows that the prevalence of L. monocytogenes in Surabaya contaminating the chicken meat samples from the supermarkets was 10% (2/20), from the mobile vendors was 0/20 (0%), and from the traditional markets was 5% (1/20). It was seen from the band at 456 bp fragment. Furthermore, three isolates found in Surabaya were included in the new lineages which were resistant to old-generation antibiotics such as sulfamethonazole-trimetophrim (SXT) and amoxyllin sulbactam (MAS), but they were still sensitive to new-generation antibiotics such as cefotaxime (CTX) and meropenem (MEM).

Identification of chicken quality parameters is often inconsistent, time-consuming, and laborious. Near-infrared (NIR) spectroscopy has been used as a powerful tool for food quality assessment. However, the near-infrared (NIR) spectra comprise a large number of redundant information. Determining wavelengths relevance and selecting subsets for classification and prediction models are mandatory for the development of multispectral systems. A combination of both attribute and wavelength selection for NIR spectral information of chicken meat samples was investigated. Decision Trees and Decision Table predictors exploit these optimal wavelengths for classification tasks according to different quality grades of poultry meat. The proposed methodology was conducted with a support vector machine algorithm (SVM) to compare the precision of the proposed model. Experiments were performed on NIR spectral information (1050 wavelengths), colour (CIEL∗a∗b∗, chroma, and hue), water holding capacity (WHC), and pH of each sample analyzed. Results show that the best method was the REPTree based on 12 wavelengths, allowing for classification of poultry samples according to quality grades with 77.2% precision. The selected wavelengths could lead to potential simple multispectral acquisition devices.

The prevalence of Salmonella was determined in chicken meat (n = 26), beef (n = 49), and pork (n = 56) collected from wholesale markets, retail stores, and traditional markets in Seoul, South Korea, in 2009. Antibiotic resistance was assessed, and the molecular subtypes of Salmonella isolates were ascertained using an automated repetitive sequence–based PCR (rep-PCR) system (DiversiLab). A total of 18 Salmonella strains were isolated from 17 of 131 samples: 16 strains from each of 16 samples and 2 strains from the same pork sample. The prevalence of Salmonella from the retail meats was 2.0% in beef, 8.9% in pork, and 42.3% in chicken meat. Among 10 different serotypes, Salmonella enterica Panama was recovered from a beef sample, and Salmonella London and Salmonella Montevideo were the predominant serotypes from pork and chicken meat, respectively. The highest antibiotic resistance observed was to erythromycin (100%) followed by streptomycin (22.2%) and tetracycline and chloramphenicol (16.7%). Of the 18 isolates, 5 (27.8%) were resistant to two or more antibiotics, and 1 isolate from chicken meat was resistant to eight antibiotics, including cephalosporins. Differentiation between all of the Salmonella isolates except between Salmonella Montevideo and Salmonella London was successfully performed with the automated rep-PCR system, indicating that it can be added to the toolbox for source tracking of foodborne pathogens associated with outbreaks.

Food can be a carrier for pathogenic agents that can disease in consumers (foodborne disease). Chicken meat is one of the products from livestock which has a high consumption rate, because besides being easy to obtain, the growth of chickens is fast, and the price is also more affordable compared to large livestock types. Chicken meat is an excellent medium for microbial growth and makes it a perishable food ingredient. Foodborne illness is a disease caused by pathogenic microorganisms that contaminate food, such as Salmonella spp, Staphylococcus aureus, and Escherichia coli (E.coli). Salmonella spp infection can cause salmonellosis which irritates the digestive tract and many of them result in death. This study aims to assess the presence and number of pathogenic microorganisms Salmonella spp in broiler chicken sold in traditional and modern markets in Bandar Lampung. The research was conducted by purposive sampling of 30 chicken meat samples. Broiler chicken carcass samples were taken as whole and then stored in sterile plastic, labeled and put into a cool box filled with ice. The variables observed in this study were the presence and number of Salmonella bacteria. The data obtained were analyzed descriptively. The results of Salmonella spp examination on chicken meat samples in traditional markets in Bandar Lampung City showed a positive  in 1 (one) sample or 6.7%, while in modern markets Salmonella was not found. The presence of Salmonella in chicken meat is thought to be due to contamination from the water used during the process of slaughtering and preparing the carcass, contamination from the carcass slaughtering and selling environment which does not apply good sanitary hygiene and poor personal hygiene of the traders. The conclusion obtained is that the number of Salmonella spp in chicken meat in traditional markets is not in accordance with SNI 7388 of 2009 concerning the Maximum Limit of Microbial Contamination (BMCM) in fresh meat.

Cadmium Zinc

Background: One of the concerns of consumers of animal protein sources is the residues of heavy metals in meat. The accumulation of these elements in meat and the consumption by humans can cause acute and chronic disorders in the function of vital organs. Methods: For the estimation of cadmium, zinc and silver in the poultry meat products, 100 samples of chicken breasts, thighs, hearts and livers were collected from meat markets in Isfahan Province. The tissues were digested and passed through filter paper, and the cadmium, zinc and silver contents were measured by an atomic absorption spectrophotometer. Results: The mean contents of cadmium in the chicken thigh, breast, liver and heart samples were 0.055±0.021, 0.048±0.023, 0.074±0.031, and 0.012±0.004 mg/kg, respectively. The mean contents of zinc in the chicken thigh, breast, liver and heart samples were 17.19±8.10, 15.70±5.75, 22.10±10.87, and 19.70±10.38 mg/kg, respectively. The concentrations of cadmium and zinc were below the international permissible limits in all samples. The mean concentrations of silver in some chicken thigh, breast, liver and heart samples were 0.0080±0.0044, 0.0048±0.0013, 0.012±0.009 and 0.0036±0.006, respectively. Of note, silver was not detected in most chicken samples. Conclusion: This study did not find cadmium, zinc and silver in the chicken meat samples above the international permissible limits. However, frequent monitoring for heavy metals in poultry meat sold in public markets is warranted to prevent their transmission to the human food chain.

Aim: The present study was designed to investigate the occurrence and distribution of Salmonella serotypes in chicken meat samples, and to explore the susceptibility of the strains to antimicrobials, as well as their virulence-associated genes. Materials and Methods: Two-hundred retail chicken meat samples from different shops, as well as 25 stool specimens from retail shop workers, were included in the study. The collected samples were examined bacteriologically for the presence of salmonellae. Salmonella isolates were serotyped using a slide agglutination test for O and H antigens and were screened for the presence of five virulence genes (stn, pef, invA, sopB, and avrA) using a uniplex polymerase chain reaction assay and for their susceptibility to 18 antimicrobial agents using the disk diffusion method. Results: Thirty-one Salmonella isolates belonging to 12 different serovars were identified. Salmonella Enteritidis and Salmonella Kentucky were the dominant serovars (22.6% each). Salmonella isolates displayed a high antibiotic resistance against erythromycin, sulfamethoxazole/trimethoprim, doxycycline, cephalexin, cefaclor, tetracycline, polymyxin B, cefuroxime, vancomycin, and streptomycin. All Salmonella isolates exhibited multidrug resistance (MDR) and demonstrated different virulence genes. The majority of Salmonella serovars (87.1%) harbored sopB gene, 54.8% carried avrA and pef genes, while all isolates carried invA and stn genes. Conclusion: The presence of virulent MDR Salmonellae in raw chicken meat could allow the possibility of transmission of these resistant serovars to humans. Therefore, strict hygienic measures should be followed on the whole poultry production chain to decrease the potential transmission of Salmonella infection from poultry meat to humans.

Background: Campylobacter species are a leading cause of most important food-borne diarrhoeal illness worldwide while, poultry has been identified as a significant cause of Campylobacter infection in humans. C. jejuni is highly effective in colonizing chicken intestinal mucosa without causing any clinical manifestations and the consumption of poultry meat is the major source of transmission of bacteria to humans. Methods: The total of 19 chicken meat samples collected from retail markets in Chennai were screened by cultural examination, further subjected to phenotypic characterization using biochemical test and genotypic characterization using polymerase chain reaction assay targeting hip O and map A genes. Result: All the isolates showed growth on modified blood free charcoal cefoperazone deoxycholate agar media (mCCDA) and 18 (94.73%) samples showed typical morphological characteristics. The 12 (63.15%) isolates showed biochemical reactions positive. The results from polymerase chain reaction showed that 10 (83.33%) isolates were positive for C. jejuni. This study suggested that, it is essential to investigate the incidence of Campylobacter jejuni infection in poultry and the risk factors at all production stages of meat production to help reducing the disease in humans in terms of food safety.

Worldwide, chicken meat is considered one of the main sources of Salmonella enterica in humans. To protect consumers from this foodborne pathogen, international health authorities recommend the establishment of continuous Salmonella surveillance programs in meat. However, these programs are scarce in many world regions; thus, the goal of the present study was to perform a longitudinal surveillance of S. enterica in chicken meat in Mexico. A total of 1160 samples were collected and analyzed monthly from 2016 to 2018 in ten chicken meat retailers (supermarkets and wet markets) located in central Mexico. The isolation and identification of S. enterica was carried out using conventional and molecular methods. Overall, S. enterica was recovered from 18.1% (210/1160) of the chicken meat samples. Remarkably, during the three years of evaluation, S. enterica was more prevalent (p < 0.0001) in supermarkets (27.2%, 158/580) than in wet markets (9.0%, 52/580). The study was 3.8 times more likely (odds ratio = 3.8, p < 0.0001) to recover S. enterica from supermarkets than wet markets. Additionally, a higher prevalence (p < 0.05) of this pathogen was observed during the spring, summer, autumn, and winter in supermarkets compared with wet markets. Moreover, the recovery rate of S. enterica from supermarkets showed a gradual increase from 20.78% to 42% (p < 0.0001) from 2016 to 2018. Interestingly, no correlation (p > 0.05) was observed between the S. enterica recovery rate in chicken meat and reported cases of Salmonella infections in humans. Higher levels of S. enterica in chicken meat retailed in supermarkets are not unusual; this phenomenon has also been reported in some European and Asian countries. Together, these results uncover an important health threat that needs to be urgently addressed by poultry meat producers and retailers.

The biogenic amines index of fresh chicken meat samples during refrigerated storage was predicted based on the headspace analysis using an electronic nose equipped with an array of electrochemical sensors. The reference biogenic amines index values were obtained using dispersive liquid–liquid microextraction–gas chromatography–mass spectrometry. A prototype electronic nose with modular construction and a dedicated sample chamber was used to rapidly analyze the volatile fraction of chicken meat samples, with a single measurement time of five minutes. Back-propagation artificial neural network was used to estimate the biogenic amines index of the samples with a determination coefficient of 0.954 based on ten-fold stratified cross-validation. The results indicate that the determination of the biogenic amines index is a good reference method for studies in which the freshness of meat products is assessed based on headspace analysis and fingerprinting, and that the described electronic device can be used to assess poultry meat freshness based on this value with high accuracy.
