HL Deb 20 November 1996 vol 575 c144WA
The Countess of Mar

asked Her Majesty's Government:

Whether any research has been conducted into the effects upon the immune systems of adults and children of repeated treatments with shampoos and lotions containing Malathion and, if so, with what results.

The Parliamentary Under-Secretary of State, Department of Health (Baroness Cumberlege)

Malathion, like all marketed medicines, is monitored on an ongoing basis for safety. There are no data to suggest that the use of malathion as a human medicine has led to any serious adverse effects.
