Over the top use by date

Seeing dates on food is something i am interested in  and i found a Jem today. It's almost Christmas and while i was in Coimbra i went to Makro. I had decided a long time ago to Have Lamb this year for my Christmas dinner. Makro have New Zealand lamb from whole lambs to all the parts all cut and prepared. On the label it only has one ingredients LAMB but then i noticed the label.

The label says to use by 16.04.2022 so much for what the NHS recommends but this Lamb was killed on the 17.04.2019. Seems an over the top Use by date,

Date and label meat in the freezer and eat it within 24 hours of defrosting. You can freeze meat for a long time and it will still be safe to eat, but the quality will deteriorate so it's best to eat it within 3 to 6 months.
