Division 4 In any case, all stocks of classical swine fever virus must be kept in secure storage, whether deep-frozen or freeze-dried. It is recommended that freezers and refrigerators are not used for viruses other than classical swine fever, or for other materials unrelated to classical swine fever diagnosis. All individual ampoules must be clearly labelled, and comprehensive records maintained of virus stocks together with dates and results of quality-control checks. Records must also be kept of viruses added to stock, with details of the source, and of viruses issued to other laboratories.
