Infection caused by Salmonella ssp. and Campylobacter spp. are the foodborne diseases reported most frequently throughout the world, and chicken meat is considered one of the most important food vehicles for both. The objective was to present the first results obtained from the integrated antimicrobial surveillance of foodborne diseases of Salmonella spp. and Campylobacter spp in three populations. In this descriptive cross - sectional of consecutive sampling, samples were collected from different sources of chicken meat and different populations for isolation, characterization and resistance profile. A prevalence of 13% in food, 20% in clinical samples and 55% in cloacal feces was observed in the isolation of Campylobacter spp. with high prevalence of Campylobacter jejuni in all three populations followed by 6% in food, 13% in clinical samples and 3% in birds cloacal feces of Salmonella spp. with predominance in the isolation of the serotype Salmonella ser. Enteritidis in clinical sample populations and birds cloacal feces. The resistance of Campylobacter spp. to ciprofloxacin of 59-81%, stood out in the three populations under study, in contrast to Salmonella spp. A high resistance to nitrofurantoin of 73% was observed in poultry feces, 55% in foods and 19.4% in humans. Resistance to tetracycline was found in foods (42%), 5% in clinical samples and 9% in cloacal feces. A resistance of 72% was observed in animals and 53% in clinical samples for nalidixic acid. It is important to strengthen the integrated surveillance of antimicrobial resistance in these three populations in order to timely detect mechanisms of resistance that can affect the human being through the food chain.
