"The ethanol industry must be wondering where the bottom is. Profits are slim or non-existent and about 20 percent of all U.S. plants are shut down. In addition, ethanol's main by-product, which is sold as livestock feed, has raised potential food safety concerns. Several studies have linked the by-product known as distillers grain to elevated rates of E coli in cattle And now, distillers grain is facing further scrutiny because the Food and Drug Administration has found that it often contains antibiotics leftover from making ethanol."
