Many facets of our entire consumer "supply chain" are in various stages of disruption. Several areas of manufacturing are having issues, and delivery service to the stores are quite "spotty". Everything in the Agriculture sector...from the farms to the stores....is having problems. Some manufacturers have switched to supplying PPE items, and medical equipment.
This virus has turned our economy upside down...40+million unemployed, and interruptions of all types of consumer items. Until there is a return towards "normal", we can expect to see empty spaces on the shelves for all sorts of items.
As more and more processing plants are having to shut down, or revamp their operations, we can expect things like meat to become increasingly expensive.
