Prevalence of Campylobacter infection in beef collected from retail market in Chuong My district, Ha Noi City

Abstract

Campylobacter is considered to be the most common bacteria causes gastroenteritis in humans in the world. Outbreaks of acute campylobacteriosis in humans were associated with consuming chicken meat products, beef and milk. The study was conducted to determine the prevalence of Campylobacter in beef collected from the retail market in Chuong My district,  Ha Noi City. A total of 60 beef samples were collected from two periods of time: summer time (July-August, 2023, 30 samples) and winter time (January - February, 2024, 30 samples). The studied result showed that the contamination rate of beef samples with Campylobacter was 13/60 samples (21.7%), higher in summer time (26.7%) compared to winter time (16.7%). Both biochemical analysis and multiplex PCR results indicated that the most common bacteria species was C. jejuni (46.2%), followed by C. coli (38.5%). This research outcomes show the risks for public health associating with beef consumption.
