THE EFFECT OF ORGANIC-ACIDS ON SALMONELLA CONTAMINATION ORIGINATING FROM MOUSE FECAL PELLETS

Laboratory mice were inoculated with a nalidixic acid and novobiocin-r esistant 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. W hen separate halves were placed into a poultry feed, either treated or untreated, with an organic acid mixture (SAL CURB(R)), the treatment was able to significantly (P < .001) reduce Salmonella contamination o f the feed by almost two log orders per gram when compared with the un treated control.
