§ Mr. Masonasked the Minister of Agriculture, Fisheries and Food whether myxosoma cerebralis is proving increasingly prevalent in wild salmonids; how many cases have been discovered to date; and if he will make a statement.
§ Mr. MacGregorI have no evidence that myxosoma cerebralis is proving increasingly prevalent in wild salmonids. My fish disease scientists have obtained positive confirmation of the presence of the parasite in a wild salmonid taken from waters in England and Wales on only one occasion.
