This is probably specific to products where spoilage is normal. If you go to a store and buy a flat of fruit (or whatever), you know some are going to be bad. Probably the same if you buy grain to be milled. (I'm not sure why wine gets a pass here; I guess some spoilage was normal?)
I wouldn't assume that this principle can be extended to manufactured goods, where the maker is presumably expected to do suitable quality control. (But I can't source it either way.)
