As a commercial farmer, a few thoughts:
Meat: The country has more than adequate meat animals. The problem is not a few packer plants have shut down due to a lack of viable healthy workers. This has created a backlog of market ready animals on the farm. Its not a supply problem but a demand problem.
Grains: The country is awash with corn and beans. The prices farmers receive for these commodities is so low that is an absolute loss every time a farmer sells a bushel. There definitely isn't a supply problem.
Vegetables: Any shortages are most likely the result of a distribution interruption. I just checked with a seed supplier, and there is plenty of seed available. One needs to get away from the huge conglomerates to find readily available produce.
