The occurrence of salmonellae during the rearing of broiler birds.
1. The incidence of salmonellae was studied in two broiler houses at each of two commercial sites in an integrated commercial enterprise. 2. Salmonellae were not isolated from the empty, cleaned and fumigated houses and only on one occasion from the foodstuffs. 3. Salmonellae were isolated from the environment of the chicks and spasmodically from the litter, water troughs and dust. 4. The incidence of infection of the chicks did not influence the number of isolations of salmonellae from the environment of the birds during rearing. 5. Water in the water troughs rather than foodstuffs appeared to be the major oral route of infection or re-infection of birds during rearing.
