My mother in law takes bacon to Crete every year. She also takes Cracker Barrel cheese, tonic water and oxo cubes!!! She used to take butter ( frozen) but a delay one year put paid to that! Over the years she has been going (20?) she has made friends with some locals and has to take Oxo for them now!
Everything she takes is vacumn packed - I don't think there is any concern re diseases but i do think it's quite unecessary
For me, one of the great delights of travel is the fact that the food is different - I can eat bacon at home so why take it on holiday with me! I love shopping abroad - the novelty of a supermarket/market/local shop in a different country knocks Sainsbury's into a cocked hat!
