Depends on how you wish to define shortage.
There is definitely a lot less to choose from in our Kroger, and purchases of beef, pork, chicken are being limited (per store visit). Ground chuck has about disappeared, nothing but ground beef.
Tomorrow I am going into our local butcher shop which sources a lot from local/regional farmers. I haven’t been in there in some time, don’t know what I will see.
If I remember, I will report back in a followup in this thread.
