HC Deb 11 July 1997 vol 297 cc639-40W
Mr. Dalyell

To ask the Secretary of State for Health, pursuant to his Department's letter of 20 June, POH (3) 5437/5 if he will assess the advantages of requiring airlines to add (a) glutaralydehyde and (b) other water-soluble oils active against viruses, to aircraft disinfectant tanks. [7934]

Ms Jowell

There would be no advantage in adding glutaraldehyde, or similar disinfectants, to aircraft sewage tanks because the normal processes for treating such sewage are considered adequate for the protection of public health.
