As for your original example, the syntax differs. Neither is your subject. If, however, you want to make a sentence that has plural fruit(s) as the subject, then try this:
- Neither the dairy nor the fruit(s) are ready to ship.
BUT you'd better tell your readers that you are using fruit as a plural noun, otherwise they will assume that you got the verb wrong. You see, most people (irrespective of what a dictionary has to say) do not consider the noun fruit plural. To them it is singular.
I ate all the cookies and all the fruit. Sorry, there's nothing more to digest.
