Mars Impact Fund awards $2.07M to Elucid for cocoa farmers' healthcare in Côte d'Ivoire

Mars, Incorporated has awarded a $2.07 million grant to Elucid, a social enterprise that runs health programmes in agricultural supply chains. The money comes through the Mars Impact Fund and will support Elucid Santé Côte d'Ivoire, the group's local arm. The three-year programme, called BLOOM, runs from 2026 to 2029. It aims to help up to 12,750 cocoa-farming households access national health insurance by removing upfront costs and administrative barriers. The grant also unlocks about $2 million in matching funds from Gavi, the Vaccine Alliance. That money will upgrade rural health facilities and extend vaccination campaigns, mobile clinics and preventive care to more than 200,000 people, including 150,000 children. Mars says the health of farming communities underpins the resilience of its cocoa supply chain.
