The "peeling" bit is based on their practice of using "night soil" (human feces) for fertilizer.

Driving through the fields (especially on a motorcycle) the morning after they have fertilized is not a pleasant experience. (To which I can attest -- personal experience...)

They even sell special disinfectant chemicals to be added to the wash/rinse water for use on cleaning fruits and vegetables.

US GIs have lots of tales about folks who tried to take shortcuts on that sanitation issue... (Ever hear of the "GI Trots"?)

I thought they gave up doing that years ago.

I remember finding myself lost in a Seoul neighborhood one time in the vicinity of a honey-bucket truck. I was fighting throwing up and trying desperately to get out of the vicinity of that damn truck.
