HC Deb 17 December 1974 vol 883 cc381-2W
53. Mr. Urwin

asked the Secretary of State for Employment what representations he has received concerning the use of enzymes in the manufacture of detergents; and, in view of the health hazards involved, if he will seek to impose a national ban on the use of such substances.

Mr. Booth

The health hazard from enzymes in the manufacture of detergents was recognised some years ago. After discussions with the Factory Inspectorate the industry set up a committee chaired by Professor Scott to co-ordinate preventive action.

Medical advisers of my Department initiated studies of workers handling enzymes and are co-operating with works medical officers of the major manufacturers in a survey to study the long-term effects of exposure to enzymes.

Improvements in environmental control of the processes in recent years have achieved a substantial reduction of air contamination to a level well below the published threshold limit value for proteolytic enzymes. A sensitive system of continous monitoring and the use of personal sampling equipment allow very close control to be exercised and I am not convinced that a national ban on the use of such substances is called for.
