HALLE, GERMANY - JANUARY 04: A lab worker prepares vials containing samples of animal feed, pork and poultry for analysis in a high-definition spectrometer for possible dioxin contamination at the State Office for Environmental Protection (Landesamt fuer Umweltschutz) in Saxony-Anhalt on January 4, 2011 in Halle, Germany. German authorities across the country are on high alert following the disclosure that the animal feeds company Harles and Jentsch GmbH had sold large quantities of dioxin-tainted animal feed to poultry and hog farmers. Authorites in Lower Saxony have halted eggs and meats shipments from 1,000 farms as a precaution. (Photo by Sean Gallup/Getty Images) less
