The chemical dioxin has been found in above-acceptable levels in the eggs of another German farm near Aurich in the state of Lower Saxony, according to the Lower Saxony state agriculture ministry.
The discovery is the latest in a string of eight other farms since April, where dioxin has been found in Lower Saxony and the neighboring state of North Rhine Westphalia. The cause of some of the outbreaks is thought to be free-range chickens living on earth contaminated by construction materials.
The currently contaminated farm holds 1,000 free-range hens. It has been sealed off while investigations are underway and its eggs cannot be sold, said authorities. The ministry has said there is no danger to public health.
