It's a problem. There's plenty of meat being raised, and plenty of vegetables and fruit being grown.

The bottleneck is in agricultural labour -- processing plants and field harvesting. It takes a lot of people to do the work, and they would normally work (and live) in close proximity. And now that's not feasible.

While this labour is low-paying, it's far from unskilled. You can't send in a bunch of unemployed urbanites to fill the gap.

Our supply chains weren't designed to adapt to this kind of event, so there are going to be hiccups. But nobody is going to starve.
