BERLIN, GERMANY – JANUARY 10: Shoppers chose from organic fruits and vegetables at a branch of German organic grocery store chain Bio Company on January 10, 2011 in Berlin, Germany. Organic foods retailers are reporting a surge in demand following the recent dioxin contamination scandal sparked by announcement by the German company Harles and Jentsch that some of the fatty proteins it had supplied to animals feeds 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. Investigators are meanwhile pursuing a criminal investigation against the leading employees at Harles and Jentsch. (Photo by Sean Gallup/Getty Images)
