A Quantitative Method for Determining the Bacterial Contamination of Dishes

A Practical Approach to Evaluation of the Germicidal Efficiency of a General Purpose Military Disinfectant

“…Ex-amples of swabbing techniques are described by the American Public Health Association (1949), Barnes (1952), Cain and Steele (1953), Higgins (1950), Buchbinder et al (1947), Tiedeman et al (1948), andAngelotti et al (1958). Agar-contact methods were used by Barton, Gorfein, and Carlo (1954), Guiteras, Flett, and Shapiro (1954), Hammer and Olson (1931), Walter and Hucker (1941), and Angelotti and Foter (1958). Rinsing techniques were used by Angelotti and Foter (1958), American Public Health Association (1953), andBell (1954a, b and1955a, b).…”

Determination of Bacterial Numbers on Tableware by Means of Direct Plating

“…While this method will recover greater numbers of bacteria than swab tests, it will not remove bacteria from cracks and inaccessible areas. The contact method of Walter and Hucker (1941), which is a modification of Olsen and Hammer's method, and the quantitative method of Guiteras et al (1954) have relatively the same deficiencies.…”
