They say there's no food then why are grocery store shelves still stripped bare?

In Los Angeles, just as grocery stores were starting to get ahead of freaked out customers stripping their shelves bare, yesterday's shelter in place order sent masses right back to the markets.  Markets are clearly having trouble keeping stocked up, so there's a problem somewhere in the supply chain.

But there is no food shortage...........right?
