Campylobacter spp. is considered to be the most common bacterial cause of human gastroenteritis worldwide. In developing countries, Campylobacter spp. diarrhea is an important cause of childhood morbidity. Chicken meat is known to be a major source of Campylobacteriosis infection in the world. The purpose of this study was to investigate the prevalence of Campylobacter spp. in chicken meat. A total of 100 samples from breast part of chicken carcass were collected from retail market in Hanoi. The samples were taken for bacteriological analysis following the ISO 10272 standards. Thirty one samples (31%) were found positive for Campylobacter spp. The most frequently isolated Campylobacter was Campylobacter jejuni (45.2%) followed by Campylobacter coli (25.8%). Due to high contamination rates of retail chicken products, special attention must be paid to good manufacturing practices of food processors and vendors. Further studies should be done to assess the risk factors of Campylobacter spp. contamination in the Vietnamese fowl production chain.
