§ Captain Kerbyasked the Lord President of the Council and Minister for Science, as the level of detecting fluoroacetate residues in plants is of the order of 0.1 part per million, what evidence is available to show that this amount or lesser amounts are not cumulative and lethal to man, cattle and dogs.
§ Mr. HoggExperimental work on various animal species has shown that fluoroacetates are rapidly eliminated from the body. With experimental rats, for example, substantially the whole of a given dose had disappeared within two days. There is no evidence to suggest that residues of 0.1 parts per million and below would be dangerous to human beings, cattle or dogs.
