Question to the Department for Work and Pensions:

To ask His Majesty's Government what assessment they have made of the impact on non-target species of the use of difenacoum, bromadioline, brodifacoum, flocoumafen and difethialone as rodenticides.

The active substances difenacoum, bromadiolone, brodifacoum, flocoumafen and difethialone, collectively referred to as Second Generation Anticoagulant Rodenticides (SGARs), are approved under the GB Biocidal Products Regulation (GB BPR) (assimilated Regulation (EU) No 528/2012) for use in pest control products against rodents.

The Health and Safety Executive (HSE) is the body responsible for the regulation of biocidal products, such as rodenticides, and undertakes rigorous scientific evaluation of biocidal products and active substances before allowing them to be placed on the market.

Risk assessments carried out by regulators, including HSE, have shown that SGARs present a higher risk to non-target species than would normally be acceptable. However, it is recognised that alternative methods of rodent control may have limitations or may not always be suitable to tackle rodent infestations. Under GB BPR products with unacceptable levels of risk may still be authorised if it can be shown that the negative impact on society of not allowing their use would outweigh the risks of using them, as is the case with SGARs.

An industry led stewardship scheme is in place in the UK for professional use of SGARs, with the key aim being to reduce the exposure of non-target wildlife to SGARs. Stewardship is overseen by a Government Oversight Group (GOG) led by HSE with representatives of other government stakeholders. The GOG receives annual reports on the residues of SGARs that are detected in barn owls (the sentinel species for rodenticide stewardship). The GOG keeps the rodenticide stewardship scheme under review, and one of the areas under consideration is extending the monitoring of SGAR residues to other species.
