The European Commission has decided to formally request Spain to change certain rules and commercial practices concerning organic farming. Some products that do not come from organic farming are marketed in Spain using the term "bio" and this is not in conformity with EU rules on organic farming. The request is in the form of a reasoned opinion, the second stage of the infringement procedure provided for in article 226 of the EC Treaty. If there is no satisfactory response to the reasoned opinion within two months, the Commission may refer the case to the Court of Justice.
