One in three supermarkets have missed out on the top rating in the Scores on the Doors hygiene rankings overseen by 100 councils around the UK.

Just 35% of Tesco stores scored the top rating, according to the Daily Mail, while a third (33%) of Asda supermarkets scooped the five-star award.

Last week the Food Standards Agency announced that it would be adopting a “broad top band” for its six-tier system so “local authorities can concentrate their resources on helping the high-risk establishments at the lower end of the scale to improve their rating”.

Retailers have consistently voiced their opposition to being included in the Scores on the Doors scheme, which they claim would suffer from inconsistencies in grading.
