The Salmonella status of 15 different farm flocks was assessed at the farm level and at processing plants. Bacteriological examination for Salmonella was made of litter, dust, feed, 5 day old culled chicks and chicken carcasses. Fresh straw litter was contaminated with Salmonella and may be a source of flock infection. Culture of floor litter can be a practical method for detecting flock infection and culture of 6 wk litter in particular would be a good indicator of carcass contamination at processing plants. Properly pelleted feed did not contain Salmonella. Processing did not render carcasses free of Salmonella.
