The Irish Laboratory Animal Science Association (ILASA), represents the interests of all sectors of laboratory animal science in Ireland. Our membership includes both Academic and Commercial entities. The mutual interest of these groups in improving the welfare of animals used for scientific purposes enables effective sharing of good practices and development of new working practices. Furthermore ILASA is a strong advocate for the development and use of the 3Rs (Replacement, Reduction and Refinement). Additionally ILASA has an active and ongoing dialogue, on behalf of its membership, with the HPRA (the Competent Authority for the sector), on matters relating to the current legislation and its application.
