I couldn't find any mention of what type of pasta she used to eat but I found a recipe of a food with raw beef which is called: Carne Cruda Alla Piemontese - I guess she was having a plain pasta with something like this beside (not mixed in the pasta as a sauce).
Note: All links are in Italian.
As I understood, Emma used to have a plain pasta to which she added raw ground (minced) beef for lunch; which in my experience and knowledge is not actually a common food in Italy and was more of a personalized diet suggested by her doctor. In this video she explains,
My doctor has told me to eat raw meat, better if minced so that I can eat it.
Referring to the fact that she was toothless.
Generally speaking, raw meat is quite popular in Italy. If you travel through different regions in Italy (specially towards south), in each of them you will find some specialized techniques to make and maintain a high quality raw meat. An an example, the city of Parma, which is famous for its raw prosciutto.
Also in most fast foods and restaurants you will find the raw meat options in the menus. Some examples are, raw prosciutto sandwich and spaghetti alla carbonara di prosciutto crudo.
