Netzingers -- Explicit coquina que est optima medicina.

Amazingly, someone is surprised by the fact that when you let animals roam around out, they tend to pick up diseases.  This may come as a shock to a history professor, but anyone who lives in a rural region can tell you that animal farms are hotbeds of micro-organisms.  Free-range animals let out to roam on the very farm where they are produced, next to the feed sheds, ponds, and sewage lagoons that are essential parts of any modern operation.

Furthermore, the idea that free-range meat production is made lucridous by the simple fact that the animal may have a different fence to look at for some part of the day, if at all.  Adding the stress of being herded back and forth to confinement with the increased risk of disease makes free range the more cruel option.
