The eggs come from two farms in Poland, agency director Yordan Voynov said at a press conference on the occasion of the agency’s first anniversary, FOCUS News Agency reported.

At the beginning of the year a ban came into force prohibiting this type of eggs – from hens bred in cramped cages.

This is the second case and we will notify the European Commission and all other member states, said Mr Voynov.

Agriculture Minister Miroslav Naydenov noted the eggs had been seized before entering supermarkets.
