HC Deb 19 January 1971 vol 809 c240W
Mrs. Joyce Butler

asked the Minister of Agriculture, Fisheries and Food what plans he has for protecting the public from hazards arising from sea foods contaminated by chemicals or other forms of marine pollution; and if he will make a statement.

Mr. Prior

My Department studies the effects on fish and shellfish and their food of a wide range of industrial and domestic wastes and monitors them for the presence of persistent and potentially toxic residues. I have recently announced that further studies will be made of mercury residues in canned and fresh fish as well as other items in the national diet.
