Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, when the UK National Screening Committee will complete its review of its recommendation not to screen children for lead poisoning.

The Government recognises how concerning lead exposure can be for parents and carers and remains committed to reducing the risk to children. Lead levels are therefore kept under stringent control, and exposures to lead in water, air, and/or food are reduced to the lowest practical level to minimise any risk to health.

The UK National Screening Committee (UK NSC) will only make a positive recommendation to screen where it is confident there is robust evidence that screening provides more good than harm. In 2018, the committee reviewed the evidence for screening children for lead poisoning and recommended not to screen at that time because:

- treatments for children with mild symptoms have not been proven to be effective and may also cause harm;

- the number of children affected in the United Kingdom is currently not known; and

- the test was not reliable enough.

The UK NSC is planning to review the evidence for screening children for lead poisoning and will undertake an evidence map, which is the first step in the evidence review process. This work is on the UK NSC’s 2026/27 workplan.

Anyone who is worried that they or their child may have been exposed to a high level of lead is advised to speak to their doctor. The local public health team can also offer advice, including practical steps to avoid further lead exposure and information on any treatment that may be needed.
