Campylobacter, Salmonella, and Listeria monocytogenes are important bacterial pathogens associated with gastroenteritis. The consumption of poultry meat and their products is considered as a major and leading source of human infection. While surveys of chicken meat and products, and its association with foodborne pathogens are widely available, such information on ducks is scarce. This survey examines the prevalence and antibiotic resistance ofCampylobacter, Salmonella and L. monocytogenes isolated from ducks. Data obtained from key surveys are summarized. The observed prevalence of these pathogens and their resistance to various antibiotics varies from one study to the other. The mean prevalence (and range means from individual surveys) are duck 53.0% (0.0–83.3%), duck meat and parts 31.6% (12.5–45.8%), and duck rearing and processing environment 94.4% (92.0–96.7%) for Campylobacterspp. For Salmonella spp., the mean prevalence data are duck 19.9% (3.3–56.9%), duck meat and parts 28.4% (4.4–75.6%), duck egg, shell, and content 17.5% (0–4.17%), and duck rearing and processing environment 32.5% (10.5–82.6%). Studies on the prevalence and antibiotic resistance of L. monocytogenes in ducks are by far very rare compared to Campylobacter and Salmonella, although ducks have been noted to be a potential source for these foodborne pathogens. From our survey, ducks were more frequently contaminated with Campylobacter than Salmonella. Campylobacter and Salmonella spp. also exhibited varying resistance to multiple antibiotics.
