“…In this study, 3 (21.4%) isolates were obtained from 14 pork samples and 1 (33.33%) isolate was obtained from 3 chevon samples. This result is found to be greater than those obtained by other research studies for pork (Trimoulinard et al, 2017;Ryu et al, 2013), for chevon (Islam et al, 2016). In our study, 1 (20%) out of 5 beef samples and 1 (14.3%) out of 7 chicken samples were analysed to be positive for L. monocytogenes.…”

Aims: Present research is focused on the molecular level characterization of drug-resistant Listeria monocytogenes identified from food and water samples from Tamil Nadu, India. Methodology and results: A total of 39 food and water samples were collected from local markets and retail shops in Tamil Nadu, India and processed for the isolation and identification of bacteria. Morphology of the bacteria was analysed under a fluorescent microscope. Isolated bacteria were serotyped and screened for the presence of virulence-associated genes haemolysin (hlyA) and invasive associated protein (iapA) by Real-time polymerase chain reaction. The qPCR positive isolates were also typed by random amplified polymorphic DNA-PCR for epidemiological study. Antibiotic resistance test was done with 16 commercial antibiotics by disc diffusion method. A total of 8 (20.51%) L. monocytogenes were identified belonging to the serotype group 1/2a, 1/2b, 1/2c and 4b. PCR assays revealed the presence of hlyA (456 bp) and iapA (131 bp) genes. In RAPD, OPA-10 primer was found to generate the distinct polymorphic fragment among the isolates. All the isolates were 100% resistant to rifampicin, co-methoxazole, linezolid and oxacillin and 100% sensitive to tetracycline and chloramphenicol. Tetracycline and chloramphenicol are suggested to be a very effective antibiotic against the tested L. monocytogenes isolates. Conclusion, significance and impact of study: The hlyA and iapA based quantitative PCR technique could be a rapid molecular technique for the detection of L. monocytogenes used in this study. Serotyping along with RAPD-PCR was able to discriminate between the isolates and therefore could serve as a robust and sensitive tool for typing antibioticresistant strains of L. monocytogenes.

“…According to data from regulatory agencies and health inspection agencies worldwide Salmonella stands out among the pathogens, as the main bacterial agent, responsible for transmit diseases associated with food consumption nowadays (Centers for Disease Control and Prevention, 2016;European Food Safety Authority, 2018). In Europe, authorities point to Salmonella as the second most important agent in foodborne disease transmission, with over 91,857 cases of salmonellosis (European Food Safety Authority, 2018;Trimoulinard et al, 2017). In the United States, the incidence of Salmonella represents 15.89% of the cases associated with diseases transmitted by food consumption (Centers for Disease Control and Prevention, 2016).…”

Evaluation of a rapid detection method of Salmonella in comparison with the culture method and microbiological quality in fish from the Brazilian Amazon

et al. 2021

Microbiological safety of fish is a concern of consumers, industries and regulatory agencies worldwide. Among the pathogenic microorganisms, Salmonella spp. is one of the main agents of foodborne diseases and should be absent in animal products. Rapid and accurate identification of pathogens in the supply chain is important for both quality assurance and tracking infectious agents within the chain. In this context, this study aimed to evaluate the equivalence of two rapid detection tests, as alternative methods to the conventional Salmonella detection method, as well as to verify the microbiological quality parameters of two commercially important fish species in the Amazon biome. The plate count of aerobic bacteria ranged from 7.76 x 10 4 to 8.71 x 10 7 CFU.g-1 for mesophiles and 1.70 x 10 6 to 4.27 x 10 8 CFU.g-1 for psychrotrophic whereas the maximum for this group of microorganisms in fresh fish is 10 6 CFU.g-1. Regarding the Staphylococcus count, the two species presented variations between 1.35 x 10 4 to 1.51 x 10 5 CFU.g-1. This represents unsatisfactory conditions of handling, storage and conservation of fish species. The immunoenzymatic and molecular methods have been shown to be reliable, fast and effective in the detection of Salmonella and for its high index of agreement with the conventional detection method. We also emphasize the convenience of multiplex PCR application due to the high sensitivity, specificity, speed and accuracy of Salmonella detection.

“…The most common pathogens causing food-borne diseases are Salmonella, Escherichia coli, Listeria and Campylobacter spp. (Ahmed et al, 2018;Oussalah, Caillet, Saucier, & Lacroix, 2007;Trimoulinard et al, 2017). The poor handling and consumption of raw and undercooked poultry and other meats are major factors responsible for food-borne diseases (Ahmed et al, 2018).…”

In this study, food grade nanoemulsions (NEs) were prepared with polyphenols (curcumin, gallic acid and quercetin); NEs were incorporated into the film forming solution at various concentrations (5%, 10% and 20% v/w of gelatin plus carrageenan). Moisture content and water solubility of film samples decreased with increasing NE concentration. Curcumin NE-loaded gelatin composite films exhibited highest antioxidant activity (27.20 ± 0.02, 45.9 ± 0 and 60.51 ± 0.36%) at 5%, 10% and 20% NE concentrations, respectively. Curcumin NE-loaded composite gelatin films also exhibited antimicrobial activity against both Salmonella typhimurium (6.97 ± 0.03 mm) and Escherichia coli (7.47 ± 0.09 mm). The chemical finger printing of films was evaluated by Fourier-transform infrared spectroscopy. Curcumin NE-loaded films showed excellent results by increasing the shelf-life of fresh broiler meat up to 17 days in comparison to control (10 days), hence can be used as alternative to conventional packaging.
