The 44th meeting of IRAC International was held at the end of March/beginning of April and consisted of a mixture of concurrent IRAC working group meetings and reviews, a meeting of the Executive Committee, IRAC España and an international session which included presentations from local Spanish experts. The meeting also was an opportunity to celebrate the 25th anniversary of the formation of IRAC and was arguably the most successful ever with an attendance of 45 international delegates. There was an excellent exchange of information with around 40 presentations made during the course of the 4 days with 2009/2010 goals and objectives set for the different working groups and teams.
