() OJ No L 46, 19. 2. 1991, p. 1. are necessary to guarantee the efficient implementation of this Decision when pigs are sent to other Member States ; Whereas, as a result of the outbreaks of the ‘new’ pig disease, the Commission adopted Decision 91/109/EEC of 1 March 1991 concerning certain protection measures relating to a new pig disease (°) ; whereas in the interest of clarity the said Decision should be repealed and a more appropriate text adopted ; ‘Whereas the measures provided for in this Decision are in accordance with the opinion of the Standing Veterinary Committee, ‘ HAS ADOPTED THIS DECISION : Article 1 For the purposes of this Decision an infected holding means a holding where unusual numbers of abortions or premature farrowings in sows or gilts and deaths and weakness in young piglets, not attributable to known diseases, have been observed within the last eight weeks. Article 2 Member States shall take all reasonable measures to avoid the spread of the disease referred to in' Article 1 within and from infected holdings.
