Not sure about that as there is not too much smoked sausage in France unless you go for the sauerkraut, sausage,belly of pork strip and boiled spuds that is sold on the deli counters or as shrink wrapped dinners ( Alsace food I think).
A previous thread a few months back mentioned that most UK supermarket meat includes that from uncastrated young boars.
In France supermarket pork is very cheap and quite good compared to the UK. pigs liver is sold in massive chunks and is very cheap.Maybe pork is cheap becau it has to complete with Veal,Beef, lamb, duck, turkey, rabbit, quail and guinea fowl. Lamb is not a best seller but every supermarket sells the above in large quantaties and pork is often on offer.
