Chris Grayling: To ask the Secretary of State for Health at what level of potency caustic soda and similar chemicals will be permitted in food supplements under the draft Food Supplements (England) Regulations; and what assessment he has made of the safety of the inclusion of caustic soda and similar chemicals in food supplements. 
Ms Blears: Neither the Food Supplements Directive nor the implementing Food Supplements (England) Regulations set levels at which the substances in the permitted lists may be used in the manufacture of food supplements.
The lists of permitted substances in the Food Supplements Directive were drawn directly from positive lists in existing European Union legislation, including that on infant formulae and weaning foods, and substances on the lists have already been assessed for safety and bioavailability by the EU Scientific Committee on Food.
As for other foods, it is the responsibility of manufacturers to ensure that food supplements comply with the food safety requirements of the Food Safety Act 1990. Calcium oxide, sodium hydroxide (caustic soda) and potassium hydroxide are permitted to be used in food at levels necessary for a technological function, such as regulation of acidity. They are used at low concentrations that do not affect the safety of the food.

Tim Loughton: To ask the Secretary of State for Health what the three month general practitioner vacancy rate figures are, broken down by primary care trust in England. 
Jacqui Smith: The three month general practitioner vacancy rate published in the Department's February 2002 vacancy survey was 2.7 per cent. for England. The vacancy rate is estimated from results of a sample of 1,000 questionnaires sent to GP practices.
In previous years there has been no way to identify which primary care trust (PCT) a vacancy was in; especially since the last survey took place prior to the formation of the existing PCTs.
In view of this and the relatively small size of the sample, it is not possible to produce reliable estimates of the vacancy rate at PCT level.
Mr. Burstow: To ask the Secretary of State for Health what steps he is taking to ensure that preparations for establishing the Health Protection Agency do not add significantly to the workload of the agencies responsible for responding to acts of bio-terrorism. 
Ms Blears: We intend that the Health Protection Agency (HPA) will be responsible for a number of functions currently performed by a number of different bodies. The amalgamation of these responsibilities into a single agency is designed to strengthen specialist support for health protection and health emergency planning.
We are working closely with the various agencies concerned to ensure that the transfer of responsibilities to the HPA goes smoothly.
Tim Loughton: To ask the Secretary of State for Health when he proposes to bring into force the Kava-Kava in Food (England) Regulations 2002.

Mr. Burstow: To ask the Secretary of State for Health (1) if his Department has started making arrangements to fast-track verteporfin PDT treatment for patients with wet age-related macular degeneration;

Mrs. Iris Robinson: To ask the Secretary of State for Health if his Department will fund a clinical study into the photodynamic treatment of age-related macular degeneration, with particular reference to subfoveal choroidal neovascularisation cases with visudyne. 
Mr. Lammy: The National Institute for Clinical Excellence (NICE) is carrying out an appraisal of photodynamic therapy (PDT) as a treatment for age-related macular degeneration. It has not yet published any guidance to the National Health Service on this topic.
NICE prepared its final appraisal determination on PDT and circulated it to consultees on 16 January 2003 We understand this document has been appealed against. NICE will now consider any appeals before publishing its final guidance.
Tim Loughton: To ask the Secretary of State for Health (1) how many hospitals are capable of intraoperative cell salvage of blood supplies during surgery; 
Ms Blears: This information is not collected. The Department published Health Service Circular 2002/009, "Better Blood TransfusionAppropriate Use of Blood", on 4 July 2002, available on www.doh.gov.uk/publications/coinh.html.
This circular asks national health service trusts and primary care trusts to review and explore the use of effective alternatives to donor blood and the appropriate use of autologous blood transfusion; pre-donation, peri-operative and post operative cell salvage by April 2003. An audit to review the implementation of this guidance will be carried out later this year.

There is no current information on waiting times.

12 Feb 2003 : Column 818W
Mr. Milburn: Memoranda of Understanding are helpful in providing a basis for a working relationship between two Governments with the aim of furthering knowledge and co-operation on health issues and ultimately contributing to the improvement of the health of their populations.
Mr. Burns: To ask the Secretary of State for Health how many times since 2001 he has taken flights on departmental duties in the UK; how many of these were (a) charter flights, (b) first or club class and (c) by helicopter; and who accompanied him on each trip.

There is no 80 per cent. target. All figures concern only those GPs providing general medical services. Personal medical service GPs have their pay and any targets determined through individual contracts with their primary care trust.
