HC Deb 29 May 1968 vol 765 cc224-5W
71. Mr. Dalyell

asked the Secretary of State for Defence what was the approximate value of guinea-pig blood sold by the Animal Breeding Centre, Porton, for any convenient dates in 1966 to 1968 for work involving research in and tests for human syphilis.

Mr. J. Morris

No guinea-pig blood as such is supplied for this purpose. Surplus guinea-pigs are supplied to the Public Health Laboratory Service on repayment, and some of these are used to provide blood required for syphilis tests.
