Lord Stanley of Alderley asked Her Majesty's Government:

Lord Lucas: Action would be taken under the Plant Health (Great Britain) Order 1993, which gives powers to inspectors to impose restrictions on any plant found to be emitting waste containing quarantine organisms. The measures required would depend on the circumstances at the time but would normally involve heat treatment and disposal in such a way as to remove any risk posed by this waste.

Lord Stanley of Alderley asked Her Majesty's Government:

Lord Lucas: Recorded imports of Dutch ware potatoes into the United Kingdom in July 1995 (the latest month for which figures are available) were 1,121 metric tonnes.

Lord Stanley of Alderley asked Her Majesty's Government:

Lord Lucas: Before implementation of the Potatoes Originating in the Netherlands Order on 23 November

1995, it was not necessary to provide this information and it is therefore not available.

Organophosphorus Pesticide Ingredients: Synergistic Properties

The Countess of Mar asked Her Majesty's Government:

    Whether they consider the effects of ingredients, other than the active ingredients, in organophosphate pesticides, insecticides, herbicides, fungicides and veterinary medicines when these ingredients may in themselves be toxic or they may have synergistic or potentiating properties which alter the effect of the active ingredients.

Lord Lucas: Assessment of data submitted by an applicant for a marketing authorisation for a veterinary medicinal or pesticide product is carried out against statutory scientific criteria including safety and efficacy, before advice is given on whether an authorisation for that product should be granted. This includes consideration of whether any individual ingredient in the formulation could have a synergistic or potentiating effect on the active ingredient in the finished product.

Top Clip Gold Shield Sheep Dip

The Countess of Mar asked Her Majesty's Government:

22 Jan 1996 : Column WA26

    Whether, when the licence was issued for Ciba-Geigy's Top Clip Gold Shield sheep dip, the fact that it would be used in conjunction with CS Disinfectant was taken into account.

Lord Lucas: As Top Clip Gold Shield sheep dip was already on the market when the provisions of the Medicines Act 1968 came into effect in 1971, it was granted a Product Licence of Right in accordance with Section 25 of the Act. This licence was subsequently varied in January 1979 to authorise the use of the product in the control of sheep scab. A further variation was granted in April 1980, to permit the use of CS Disinfectant as a bacteriostat if dipping could not be completed on the day the dip was prepared. This followed consideration by the Veterinary Products Committee of its use in conjunction with the sheep dip.

The Countess of Mar asked Her Majesty's Government:

    Why the withdrawal periods for CS Disinfectant (28 days) and the organophosphate, Diazinon, (14 days) were not harmonised when sold together for combined use in Ciba-Geigy's Top Clip Gold Shield and whether they consider that there as an inherent risk that users would observe only the shorter period.

Lord Lucas: I am not aware of a 28-day withdrawal period being imposed for CS Disinfectant. If the noble Countess could provide me with any details she has, I will arrange for them to be looked into and will write to her, placing a copy in the Library of the House.
