HC Deb 31 January 1958 vol 581 c118W
Sir A. Bossom

asked the Minister of Agriculture, Fisheries and Food if he will permit supplies of crystal violet vaccine to be made available to farmers to combat swine fever.

Mr. John Hare

Crystal violet vaccine is suitable for use only in skilled hands and for this reason the supplies produced at my Department's veterinary laboratories are sold only to veterinary surgeons. I do not control the distribution of the small quantities of crystal violet vaccine imported under licence.
