Experimentally Killing Salmonella typhimurium on Egg Shells by Washing

Abstract

BIERER et al. (1961) found that commercial egg washing compounds possessed varying degrees of efficiency in removing or killing bacteria from egg shells artificially contaminated with a broth culture of Salmonella typhimurium. Consequently, the search for a chemical of chemicals superior in germicidal effect was instituted. The scheme of investigation was in the following directions: To observe the germicidal effect of commercial egg washing compounds when used at higher levels. To test each of the individual ingredients of commercial egg washing compounds for germicidal effect. To test representative commercial disinfectants and germicides and individual chemicals of known germicidal value. To review individual chemicals in general and select for trial those likely to possess germicidal value as an egg wash. The culture of Salmonella typhimurium used was a strain adapted to turkeys and had been propagated on tryptose agar slants and preserved by refrigeration for several years”
