My paper starts with a brief description of EFPIA, which was established in 1977 to represent the pharmaceutical industry in W. Europe and refers to its changing role in the animal health field within the past year. It consists of sixteen pharmaceutical industry associations. The Trade Associations representing the animal health industry in certain countries in W. Europe, saw a need for collating and issuing reliable national data on their members' sales over a decade ago. These reasons will be briefly discussed. The objectives of the Federations' audit have been to collate as accurately, and issue in as much detail as possible, the national data collated by its member Associations.
