Abstract

|
|
The following results were obtained through an bacteriological investigation on 300 cafeteria utensils used at a college boarding house.
1. Positive rate for general colony count over 100/ml was 17.9%, and that of coli-form bacteria was 24.6% out of all utensils examined.
2. Positive rates for general colony count and coli-form bacteria were the highest in the utensils after lunch, and those after dinner and breakfast came next in order.
3. Positive rates for general colony count and coli-form bacteria were higher in utensils while they remained moist than they were dry.
4. General colony count and coli-form bacteria decreased in number as time passed after washing of the utensils. They, however, showed a tendency to increase in number afterwards when the utensils were laid on a shelf.
5. None of E. coli was found among the coli-form bacteria from the utensils.
