Did you end up selling fruit through the inventory of a sim? Since either Supernatural or Seasons (not sure which, it's when I came back and the difference for me was both these expansions), if I sell stuff through my inventory, some of the time a copy will appear on my lot as well as giving me money. Happens with things from cars to produce to books. If that is happening and the objects are appearing on the space where the food bowl is, that could be the issue.
