I got this from this this website ^
Summary
" If you don’t put your hands in your mouth, don’t eat uncooked foods prepared in a restaurant and don’t eat raw or steamed shellfish it is impossible to contract a Norovirus. "
^
"uncookred foods prepared in a restaurant" = does this mean only if food is not cooked properly? Or are they referring to salads and fruit bowls in restaurants as well?
