Lazily copying my comment on the other thread now started on this subject:
I do not believe what the story suggests about this being something new. I grew up just outside Philly, with relatives on the police force and thus a certain amount of gossip about a) illegal activities in general and b) mob activities in various East Coast cities, and I am just absolutely positive they used to talk about tractor trailer loads of food as being one of the sorts of items that not-infrequently would go astray in transit so to speak. Mind you this would have been the 60s and 70s, I have no idea about more recently, but, still.
