Research note: the effect of organic acids on Salmonella contamination originating from mouse fecal pellets.
Laboratory mice were inoculated with a nalidixic acid and novobiocin-resistant strain of Salmonella typhimurium. Contaminated fecal pellets were harvested 2 days postinoculation. Each half of a fecal pellet was found to contain equal numbers of Salmonella on a per weight basis. When separate halves were placed into a poultry feed, either treated or untreated, with an organic acid mixture (SAL CURB), the treatment was able to significantly (P < .001) reduce Salmonella contamination of the feed by almost two log orders per gram when compared with the untreated control.
