The chemical dioxin has been found above permitted levels in eggs from a German farm in Lower Saxony, according to the state agriculture ministry, the seventh farm to be found contaminated since April.
The farm and its 12,000 chickens have been quarantined and its eggs recalled from sale. The farm discovered the dioxin during its own safety checks, said the ministry, and there is no acute danger to public health.
The previous dioxin cases were in eggs at farms in Lower Saxony and the neighboring state of North Rhine Westphalia. In January 2011, a European Union-wide health alert was announced when dioxin-contaminated animal feed in Germany fed to hens and pigs led to contaminated eggs, poultry meat and pork at affected farms. The outbreak led to Germany introducing a series of measures including restrictions on animal feed ingredients and increased inspections of farms and feed.
