Harvest is underway and a few issues stemming from the unusual weather patterns last summer are coming up. On September 30 the Iowa Department of Agriculture and Land Stewardship (IDALS), as the state representative for the U.S. Food and Drug Administration, issued a statement saying that grain submerged (over the grain) in flood waters was to be considered contaminated and therefore not eligible for entry into food-feed markets. Ethanol is a feed market because of the dried distillers grains with solubles (DDGS). This is the same policy that was used for grain in storage that was submerged in 2008 by the eastern Iowa floods. The logic is that, in addition to in-field mold issues (see example below), flood waters can contain many contaminants from a wide variety of sources
