German authorities are investigating allegations of fraud over the mislabelling of eggs as organic.
The northern state of Lower Saxony has launched an investigation into allegations that 150 farms had mislabelled their eggs.
It is claimed that the hens live in conditions that do not confirm to organic regulations.
The farm minister said that if the accusations are proved to be true, it would be "fraud on a grand scale".
Farm Minister Ilse Aigner said in a statement that the mislabelling of eggs would be "fraud against consumers but also fraud against the many organic farmers in Germany who work honestly".
The investigations come as Europe's food industry has been engulfed by a meat processing and labelling scandal after multiple processed meat products labelled as beef were revealed to contain quantities of horsemeat.
