Should You Sell Uncovered veggies at the grocery store? In Water?

I have passed by this grocery store in Ottawa many times and there is always these containers of cut up vegetables in water and there is no cover on the vegetable containers.
Would not be surprized if people put their hands in them!
There is a "sneeze guard" part but it is not enough when the products are displayed at such a low level.
Everything else that is sold in this case is in closed containers, wrapped up half melons,cut up pineapple.
What are your thought on this.
