This work aimed to verify Salmonella occurrence in laying hen flocks from eight poultry farms in Metropolitan Region of Fortaleza city. Swab collections were performed in transport boxes of day-old-chicks, totaling 40 feces samples (5 samples/flock), which presented no Salmonella contamination. Bacterial analyses from a pool of feces were performed in the same flocks at 10, 20, 30 and 40 weeks of age. Salmonella enterica rough strain and Salmonella Newport were found in two flocks at 20 and 40 weeks of age, respectively. These results suggest that the birds were infected with Salmonella after their arrival in the poultry farms. It was verified that 25% of the poultry farms presented positive feces samples for Salmonella contamination, indicating the need for a more efficacious preventive program in the poultry farms for egg production. This work suggests that day old birds were of Salmonella contamination which indicates no vertical Salmonella transmission, however the rearing phase present failures regarding bacterial control. KEY WORDS: Bacteriology, chickens, eggs, feces, Salmonella.
