A new campaign has been launched to put pressure on the NHS to examine where its medical instruments come from.
The British Medical Association (BMA) wants more Fairtrade and ethically-sourced kit to be used.
It says at least a fifth of surgical instruments are made in northern Pakistan, where child labour is common.
Ministers said "exploitation of any kind was unacceptable" and the Department of Health was working with the BMA to develop practical guidance.
