The Home Office is the lead department and completed the recommended review in May 2026. Next steps are set out at paragraph 59.

A targeted review of the sale and availability of castor beans in the UK has been completed. This work has considered the potential misuse of plant-derived toxins, including ricin, alongside existing regulatory frameworks and the need to balance legitimate use with the risk of malicious acquisition. The review examined the risks associated with the availability and acquisition of castor beans, including issues relating to bulk purchasing. It also developed and assessed a range of potential policy responses to address these risks, including voluntary measures and possible regulatory approaches, informed by evidence on the availability and use of castor beans. Home Office ministers have reviewed the conclusions from the review and the options identified and agreed that further work should be taken forward to develop and test these options. The Home Office are working with relevant departments and stakeholders as this work progresses and will keep the Chair of the Inquiry apprised of developments, including any subsequent actions taken, such as consultation, including in relation to Recommendation 13.
