Slightly off the bacon topic (this is about BEEF) but....
If you have a local meat market, one of those small mom-n-pop types, try them out. You will probably find that the meat is of greater quality that stuff bought in the "big" stores.
Example - on the surface, buying your ground meat in the "chubs", those plastic tubes, because the price per pound is less, is NOT 'cheaper'.
Consider this. When I make a 1 # meatloaf (no crackers, bread crumbs or anything else to absorb moisture), using the 93% lean chub, I usually end up with about a cup of liquid and a meatloaf that has shrunk about 3/8" all the way around the pan.
When making a meatloaf with "lean" ground beef from my local market following the same process, the shrinkage is considerably less and there is less than 1/2 cup of liquid in the pan.
The extra liquid and subsequent shrinkage comes from the fact that the big boys add ICE to their ground meat while grinding it up. So if you pay less per pound but you have less meat per pound.
They probably also inject water into their bacon before slicing and packaging it, so it shrinks more when cooking it.
