Are any European meat markets going to be open in Europe this summer?

Switzerland's sauna clubs etc. already are, and Austria's open 1 July.

I think you are better off trying from September onward.

Whilst there must be some e.g. Switzerland as the above poster has mentioned.

Would you be willing to risk it?

I have taken the cautious approach and have just completely taken mongering out of the year 2020.

Looking for a return to complete normality by Easter 2021.

Best wishes!
