Barking and Dagenham has become the latest council to make sure that all fish served in school meals will be demonstrably sustainable.

The borough signed the Sustainable Fish Cities pledge, which covers all the area’s 3.5million primary and secondary school dinners every year.

The commitment will support fisheries and fish farms proved to be working sustainably, and from stocks that are healthy.

Sustainable Fish Cities is a campaign aiming to kick unsustainable fish off menus in the UK for good.

The commitment comes just weeks after Northbury Primary school became the first school in the borough and the seventh in London to win a gold award for their healthy eating.
