Abstract
Iced milk tea and iced coffee at five refreshment shops around Kamphaeng Phet Rajabhat University were examined for possible Salmonella spp. contamination during the period between September and November 2019. It was found that the percentage of the total of 60 samples was 30 percent containing Salmonella spp. which were isolated and identified by biochemically tested for 18 isolates. A sampling isolate, identified based on 16S rRNA gene sequencing, was Salmonella enterica so this confirmation of all isolates was Salmonella spp.. The prevalence of Salmonella spp. in iced milk tea and iced coffee was 18.33 percent, and 11.67 percent respectively. All 18 isolates were tested for their antimicrobial susceptibility pattern by disk diffusion technique. These Isolated resistant to many drugs which pose a risk to consumers.
