You haven’t read anything here lately about ethanol. Here’s something about feeding distillers grain, an ethanol byproduct, to cattle. It’s being studied at Colorado State University. Selling the grain to farmers for cattle feed is a big part of the ethanol industry, but too much of the stuff could cause problems:

Increased sulfur in the distillers grains comes from adding sulfur to the ethanol machines, Archibeque said. High levels of sulfur can cause sulfur toxicity in cattle. While that doesn’t taint meat, cattle suffer neurological damage that causes the animals to ram their heads into the wall, stare up at the sky and, if not treated, die.

It’s also said to increase E. coli levels in cattle manure by 50%, increase phosphorus levels by a large amount and might have an effect on the quality of meat and dairy products.

So if you have a new use for the more than 10 million tons of the stuff produced every year…. There might be less of it going into the mouths of cattle.
