My remark was not aimed at farms particularly, but at the industrialization of the industry and operating on a larger scale. My point is that when you're in that situation—and I made the analogy with aviation, where you're flying larger planes and more people—it means that when there is some kind of problem, it can be a much more serious problem with more loss of life.
We all understand that in the past when there were lots of small farms, occasionally a farmer might have some kind of problem and sicken some of his neighbours, but it would be unlikely in the past that a single peanut plant, for example, could cause the largest recall in U.S. history.
