Two commercially available litter treatments, aluminum sulfate and sodium bisulfate, were tested to determine their effect on Campylobacter and Salmonella levels associated with commercial broilers during a 6-wk grow-out period. A total of 20 broiler houses at 10 different locations were studied; 5 aluminum sulfate-treated houses, 5 sodium bisulfate-treated houses, and 10 paired, untreated control houses. A single application rate was investigated for each treatment. Fecal samples (n = 20 per house) were analyzed at wk 2, 4, and 5 and 6 for Campylobacter and Salmonella. The results indicated that, at the application rates investigated, both acidifying litter treatments caused a slight delay in the onset of Campylobacter colonization in broiler chicks. Salmonella levels remained unaffected, with no significant effect seen with either treatment (P > 0.05). Campylobacter populations and Salmonella incidence associated with unprocessed, whole-carcass rinse samples (n = 10 per house) analyzed at the end of production (wk 5 and 6) were unaffected by treatment.

Key Words: Campylobacter • litter treatment • Salmonella • aluminum sulfate • sodium bisulfate
