§ Mr. Hoosonasked the Minister of Agriculture, Fisheries and Food what areas of the country are now affected by the presence of Warfarin-resistant rats; and to what extent these areas have increased in the course of the past two years.
§ Mr. John MackieThere have been no confirmed reports of Warfarin-resistant rats from any areas of England and Wales beyond those my hon. Friend the Joint Parliamentary Secretary gave to the hon. Member for Montgomery (Mr. Hooson) on 27th May.
It is not possible to say with any accuracy how far Warfarin-resistance has spread during the past two years within the affected area but until 1965 its presence had not been confirmed in two of the ten districts in which it is now known to occur.—[Vol. 729, c. 167–8.]
§ Mr. Hoosonasked the Minister of Agriculture, Fisheries and Food how many field officers and operators have, during the past few months, been working full-time on the campaign to slow down the spread of Warfarin-resistant rats.
§ Mr. John MackieFour rodent operators have been employed full time on this work since March under the supervision of a field officer.
