Germs on Groceries Killed by Rays (Apr, 1946)
Germs on Groceries Killed by Rays
Housewives now can return home from shopping with germ-free groceries. A new “germ-killer,” designed for use in food stores, bathes the groceries in ultraviolet light. The unit is a plywood box with a large opening at one end. Baskets or carts of groceries, contaminated by handling, are placed in the box through the open end. Inside are three ultraviolet lamps that pour “condensed sunshine” over the foods. After 30 seconds the foods are withdrawn germ-free.
