There have been stories of food shortages, dairy farmers dumping milk, and farmers forced to reduce their herds. This article explains why this is the case. Some of the comments are also very illuminating.

To summarize, traditionally 60% of food in America is prepared and consumed outside the home. That portion has now been reduced to zero, which doesn't mean that less food is being eaten, only that it is all being eaten at home now. Problem is that much of the food packaging has necessarily been targeted to the wholesale market, not the retail market that provides food for the home. The retail packaging industry was already running at near 100%, great for corporate efficiency, but impossible to ramp up to meet the suddenly increased demand. The 60% that was going to the wholesale market is now largely unusable. Thus the need to scale back production, which is unfortunate in the face of undiminished demand.
