Aside: Contract consumable manufacturing is how most packaged food is made in the US. Essentially, things like packaged cookies, that new craft beer, or frozen enchiladas are all made in the exact same place with the exact same equipment, even brand name, just a different recipe. These places tend to be very tightly controlled in terms of sterility, tastes, particulate matter, mold, ingredient source, etc. Most of those boxes from those central shelves in your Safeway are all from the same handful of places.
