I would estimate it’s like <10% of Germans who eat raw pork (“mett”, I wonder if the word is etymologically related to meat). In younger generations even fewer that eat it. There also may be a regional factor to it.

Mettigel is the stereotypical “70ies dinner party” dish that grosses people out.

And for regular meats, steaks, etc. people like to eat it rather well-done. If I want to get a steak done medium I order medium-rare here. People will order medium and complain to the chef if it’s actually medium. The whole spectrum of is shifted to the well done side.
