§ Mr. Boyesasked the Secretary of State for the Home Department if he will seek powers to prohibit the use of the LD 50 poisoning test.
§ Mr. MellorThe Government welcome the growing recognition by the scientific community and regulatory bodies that formal LD 50 tests are increasingly not necessary. Where they are shown to be necessary, however, they will continue to be allowed, subject to strict controls. Wherever possible a limit test or some other alternative method should be employed.
