The Talmud (Chulin 17a) discusses that certain peices of pig meat are permitted:
השתא דבר טמא אישתרי להו דכתיב (דברים ו, יא) ובתים מלאים כל טוב ואמר ר' ירמיה בר אבא אמר רב כתלי דחזירי בשר נחירה מבעיא
Now, non-kosher items are permitted for them, as it is written: “And it shall be, when the Lord your God shall bring you into the land that He swore to your fathers, and houses full of all good things…and you shall eat and be satisfied” (Deuteronomy 6:10–11), and Rabbi Yirmeya bar Abba says that Rav says: pieces of pig meat are permitted for them; certainly the meat from the stabbing of a kosher animal is permitted!
Rashi comments on this to qualify the pig meat as bacon.
כתלי דחזירי - חזירים יבשים שקורין בקונ"ש
Pieces of pig meat - dried out pig meat, which we call bacon.
I know that this is only Talmudic dialogue, however, does this law stand until today, what is the modern law?
