Abstract
We investigated the degree of bacterial pollution with marketed green pepper, lettuce and cucumber which were packed in film bags, and experimented with removing the bacteria by washing. The results obtained were as follows.
1. The degree of the bacterial pollution varied with samples but in general it was found to be unexpectedly high 21 × 106 was the highest count for bacteria and 95 × 104 was that for E. coli.
2. By two-minute gentle washing in a usual way which is adopted by household, 40-90% of bacilli were washed off from green pepper and lettuce, but only 5-40% from cucumber.
3. When the vegetables were washed gently in such a way as stated above, water with detergent worked more effectively than plain water.
