Background: Salmonellosis is caused by bacteria of the genus Salmonella and is a worldwide-considered major zoonosis with a risk for the public health due to the capacity of dissemination between animals and nature. In the poultry industry, day-old chicks may acquire the infection at the hatchery through contact with fomites and eggshells with the presence of contaminated feces, favoring the animal infection and may become a source of infection to other birds in the lot, as well as to several other animals, including man. The aim of this study was to verify the presence of Salmonella spp. in one-day-old chicks from hatcheries in the metropolitan region of Fortaleza, Brazil.Materials, Methods & Results: A transversal study with a convenience sampling was performed in 510 day-old chicks acquired from five hatcheries located in the metropolitan region of Fortaleza, Brazil. From each hatchery, 102 day-old chicks were analyzed at the Laboratory of Ornithological Studies (LABEO) of the State University of Ceará. Individual cloacal swab samples were collected immediately after arrival, following euthanasia by cervical dislocation for organ sampling, comprised of a pool of livers and yolk sacs of three birds per sample. Organ and cloacal samples were incubated in pre-enrichment using buffered peptone water 0.1%, following selective enrichment with the broths: Tetrathionate, Rappapo
