Chicken and pig exports 1961-2011To get a handle on the world’s traffic in livestock for a paper I’m co-authoring, I graphed FAOSTAT data on global live chicken and pig exports by head, 1961-2011.

The time series appear to track geographically lengthening production-demand discrepancies–areas of high production meeting demands elsewhere. Globalization exploded in chickens by 1990–not long preceding bird flu H5N1–and, after a starting wobble in the 1990s led by the United States and NAFTA, in pigs by 2000.

Indeed, even excluding illegal trade the stats don’t pick up, pig exports more than doubled by the end of the decade, when swine flu H1N1 (2009) appeared with genomic segments from influenzas circulating among pig populations in both Eurasia and North America. New agricultural ressortants appear to be accumulating at an accelerating pace since, including H1N1v, H1N2v, H3N2v, H7N9, and now a new series confirmed last week, H6N1.

Bird flu marinates a chicken in its own juices, a satay best avoided whatever the menu special. In such short an order better for the bistro than the barn infected birds rapidly bleed from the inside out.

What to do about this bit of bad news?

Broilers and layers are as much commodities as they are birds. As much engineering problems as living organisms. So ask research and development for a solution comes the answer.

It was, after all, by virtue of its open morphogenesis and behavioral flexibility that the chicken was first domesticated multiple times from red and grey jungle fowl distributed across South and Southeast Asia, artificially selected for the backyard, then scaled up in size and population to its factory model.
