A Survey and Prevention of Salmonella Contamination of Chicken Meat

III. Effect of Chlorination against Salmonella Contaminating Feathers and Skin in Dressing Plants

Abstract

Chlorination with less than 1, 000ppm of chlorine was not effective at all against Salmonella contaminating the skin. Chlorination with 2, 000 ppm, however, showed a germicidal effect when performed simultaneously with agitation by a stirrer.
Sensitization with 200ppm of chlorine water for 10 minutes was destructive to Salmonella contaminating feathers when the number of contaminating organisms was less than n×10². When it was carried out concurrently with agitation by a stirrer, it became so markedly germicidal as to kill n×10⁴ organisms in 10minutes.
When residual chlorine was 50-100ppm, it destroyed Salmonella contaminating water used for working in the dressing plant and cooling.
