Young pigs are seen in their pen at the Ebsen organic farm on January 13, 2011 in Langenhorn, Germany. Organic foods retailers are reporting a surge in demand following a recent contamination scandal. Investigators are pursuing a criminal investigation against the leading employees at Harles and Jentzsch - which announced some of the fatty proteins they had supplied to animal feed producers was tainted with dioxin. German authorities responded by barring 4,700 mostly poultry and hog farms from selling their products until laboratory tests could guarantee them dioxin free. Organic farms have thus far been immune from the scandal since they use no industrially-produced animal feed. By Joern Pollex/Getty Images.
