This article reports that in 1993, 18% of hog operations in the U.S. had more than 5000 animals, now 53% do. At the same time, more people are moving from the city to rural areas. The confluence of more people and more pigs has sparked a slew of complaints and much litigation. In 2004, for instance, a state appeals court in Nebraska, a major pork-producing state, ruled that a hog farm must compensate its neighbors for enduring smells some described as a suffocating stench. In laboratory studies, Jerzy Dec, a senior research associate at Penn State University, and his colleagues mixed horseradish root with hydrogen peroxide or calcium peroxide. Horseradish root contains large amounts of peroxidase, an enzyme that when combined with peroxide destroys phenols, a common source of odors in manure, through oxidative coupling.
