Twilight Greenaway at Grist: Antibiotics in your meat? The ethanol industry might be partly to blame

Like many dairies and livestock operations, the farm owners had been able to lower their feed costs by using the byproducts of industrial food and fuel production. Towering around us that day, we were told, were giant piles of canola pellets, cotton seeds, and soy hulls (from oil production), and dried distillers grains (from ethanol production). I bookmarked the image in my mind and I’ve been considering it ever since, especially as I’ve heard about the aquaculture industry moving toward a grain-based model to avoid feeding wild seafood to farmed fish. In both industries (agriculture and aquaculture), it’s not hard to see why distillers grains are so popular. They’re affordable and the ethanol industry has been pushing them hard in recent years, because, as Tom Philpott pointed out a few years back, “finding a high-value use for this ‘coproduct’ is absolutely vital to the corn ethanol project.”
