Public Health Agency of Canada says raw lettuce, the base of most salads, is impossible to clean. When traveling, they recommend foods that have been cooked "and served piping hot."
"Fruits and vegetables should be either freshly peeled or freshly cooked."
Grapes, strawberries and raspberries are hard to clean.

Dunno the effectiveness of washing in high-proof liquor, but this wash-liquid probably is drinkable- no waste!

I am a peel eater. I take my chances. Nude food is immoral!
