From trusted source in Hong Kong today:
“In our laboratory, we found trace amount of the virus on the skin of fruits and vegetables after 12 hours of being touched by another customer who was infected.

We recommend our staff to avoid salads. Do not eat the fruits within 48 hours of purchase, or pour some boiling water over the fruit before cutting. Berries, apples, cucumbers and tomatoes are the worst because some people eat the skin.

This explains why the virus is spreading faster in the west than asia. Most Asians do not eat salad and very few people eat the skin of any fruit.

We have to assume anything that comes from outside our home within 48 hours is infected. Shoes, clothes, our hair, all food.”
