Nineteen organic egg farms in Germany and eight in the Netherlands have had the sale of their eggs embargoed due to dioxin contamination. Sales from the farms have been suspended for at least a week.
The contamination is thought to be the result of contaminated corn from the Ukraine used in feed. The grain is reported to have been processed in organic poultry feed by a number of companies.
Dioxin contamination of eggs hit the German headlines back in 2005, with calls for greater controls on free-range production, which may result in eggs with higher dioxin levels than those from caged birds.
Neither details of the level of dioxin contamination on the farms, or how the feed may have become contaminated are known. Investigations are ongoing.
