56. Mrs. Butlerasked the Minister of Agriculture, Fisheries and Food whether he is satisfied that no danger to public health will result from the arsenite spraying of potato foliage on this year's crop; and if he is yet in a position to make a statement.
§ Mr. GodberBy voluntary agreement, the use of alkali arsenites will cease after the 1960 potato harvest. Surveys have shown that potatoes from crops treated with alkali arsenites do not contain residues dangerous to consumers. The main risk is to operators and to cattle but I am confident that those concerned will exercise the most stringent safety precautions in this final season of use and that the extra period will be of great value for the commercial development of suitable substitutes.
