Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, what estimate the Food Standards Agency has made of the risk of lead contamination in (a) silage and (b) animal feed produced on floodplains downstream of historical lead mining sites.

The Food Standards Agency (FSA) is planning to review dietary lead as part of its rolling programme of risk analysis of environmental contaminants in food. This will include consideration of areas where exposure is likely to be higher. Scoping work has started, including considering what, if any, additional evidence and data may be required.

The FSA has not undertaken a specific estimation of the risk of lead contamination in silage or animal feed. However, in conjunction with the National Farmers Union, the FSA has provided advice to farmers to mitigate against lead entering the food chain, and how to avoid lead contamination. In addition, maximum levels for undesirable substances in products intended for animal feed have been established in Schedule 4 of the Animal Feed (Composition, Marketing and Use) (England) Regulations 2015, with further information on the regulations available at the following link:

https://www.legislation.gov.uk/uksi/2015/255/schedule/4

This includes levels for lead in feed materials and forage, which includes hay and silage. Any product which exceeds these limits is not permitted to be placed on the market. These regulations are enforced by local authorities. Under animal feed legislation, feed businesses, which include farmers, are responsible for making sure the feed they produce is safe for the animals it is intended for.

The impact of flooding on areas of land with historical levels of lead contamination is a matter for local councils to consider under Part 2A of the Environmental Protection Act 1990. They have the duty to inspect their areas to identify contaminated land. This would cover situations where lead is washed from rivers or sediments onto floodplains or where existing lead contamination on land is impacted by flooding. Lead may be discharged into rivers from abandoned metal mines and the Environment Agency is working with the Coal Authority under the Department for Environment Food and Rural Affairs’ Water and Abandoned Metal Mines Programme to identify and tackle the priority discharges.
