Abstract:
Foodborne disease is a significant health concern for scientists and populations in Vietnam. While Salmonella is considered the most cause of foodborne illnesses, chicken meat is a main source of this disease. We conducted this study to investigate the presence of Salmonella in distributed chicken meat in Hanoi city, Vietnam. In the first quarter of 2023, we collected 100 samples of chicken parts (head and neck, breast, drumstick, and wing) from street markets around 8 districts in Hanoi city to test the presence of Salmonella. TCVN 10780-1:2017/ISO 6579-1:2017 Microbiology of the food chain - Horizontal method for the detection, enumeration, and serotyping of Salmonella - Part 1: Detection of Salmonella spp. was used to detect Salmonella in the sample. In parallel with that, polymerase chain reactions to detect Salmonella with DNA taken from typical Salmonella colonies on selected agar were also performed. The results show that 70 chicken samples (70%) were contaminated with Salmonella spp.. None of them was Salmonella enterica (Salmonella typhimurium and Salmonella enteritidis). Results show a high prevalence of Salmonella in chicken meat. Therefore, the improvement of food conditions in street markets is highly recommended.
