Despite the ridicule from Sen. John McCain and other Republicans, Iowa and the federal government have been studying how to control hog odors for years. The latest grant continues efforts under way at the Agricultural Research Service at the U.S. Department of Agriculture labs in Ames, Iowa.
Both parties are bad at pork barrel spending but this to me just shows how bad it is they have been studying it for years. I could tell them how to prevent this stop having large feed lots close to people. Go back to a farmer having a few pigs on each farm or move the feedlots to areas without other people. They can study study study study as long as they like but it will still smell like pig Sh$t.
