Understanding drivers of private-sector compliance to large-scale food fortification: A case study on edible oil value chains in Bangladesh

Highlights: •Co-existence of non-fortified products disincentivizes producers to fortify. •Limited product traceability disincentivizes producers to comply with the policy. •Economic pressure prevents small-scale producers from adequately fortifying. •Political tension leads to inconsistent law enforcement, and limited compliance. •Enforcement should focus on the origin of bulk items by large-scale producers.
