AB BACTERIAL EXAMINATION OF EATING UTENSILS 
    In a survey of the bacteriology of eating utensils, Carlisle and Hartinger1 followed the technic employed by Cummings and Yongue, using brain-veal agar and plain agar in petri dishes as the culture mediums. The cultures from "clean," recently washed plates, cups, glasses and spoons which had been handled but not used for meals showed a total bacterial count for the entire surface of the plate, cup, glass or spoon ranging from 64 to 110, whereas cultures from used unwashed utensils showed a content ranging from 38,000 to 190,000. Dishwater remaining after washing dishes which had been handled and used by patients and personnel showed a bacterial count of 80 per cubic centimeter. This is below average expectation and means that few bacteria survive the exposure to hot soapy dish water. Dishes that were washed in hot soapy water at 172 F. and then rinsed
