Just Eat has said it will introduce a trial of hygiene score listings on its site amid criticism that some zero-rated establishments are included on the app.

An investigation by the BBC found that half of outlets rated as zero by the Food Standards Agency in Manchester, Bristol and London appear on Just Eat.

Just Eat said it was “actively working to raise standards” andoffered free accredited food hygiene training to any restaurant that signed up to the platform. It said a trial would begin in Northern Ireland.

It added: “Whenever any potential food safety issues are brought to our attention, our restaurant compliance team will review, investigate and liaise with the local authority.”

The company pointed out that for each outlet, it already does include a link to the Food Standards Agency website, at the bottom of both the menu and the information page. Customers do then need to input the name and postcode of the restaurant on the FSA website to find the relevant hygiene rating.
