Oh dear, that doesn't sound good. But there is hope! After a quick google of "where is the bacon in France?" (which sounds like it could be the title of an indie pop hit single), this came up:

i’ve heard about loads of expats having a hard time finding bacon in france, which leads to ranting and cursing the living hell out of our francophone home country. i should consider myself lucky because we go to a nearby farm for organic produce, eggs and meats, and amazing bacon. many of you are nowhere near a farm and might not be able to find the same quality bacon BUT! never fear, you CAN and WILL find bacon in paris; i swear. no, it’s not smoked ham or bits and pieces of fat lardons. you just need to ask the butcher for de la BARDE. french people don’t pan fry them and eat them crispy and on their own. they usually wrap bacon around other meats in a terrine or a roast - but it IS bacon, thinly sliced, just like you need them to be for breakfast!

Good luck! My pary are with every redditor who cannot find bcaon.
