A Preston takeaway given a zero rating by health inspectors earlier this year has now risen to four stars.
The Manzil takeaway in Adelphi Street was among the two lowest scoring premises in a list of 29 outlets identified by Preston Council in January.
Takeaways, restaurants, market stalls, sandwich shops and even a school canteen were among the outlets offered free food hygiene coaching by environmental health officers.
Preston Council wrote to establishments with a history of poor inspection performance and Food Standards Agency ratings of two or lower out of five.
Manzil was among the lowest scoring premises in a list of outlets targeted by environmental health officers.
Manzil owner Abdul Majeed said he was delighted with the new rating.
Mr Majeed, who has owned the business since March last year, said he had personally taken over management of the shop when problems were highlighted.
He said: “We knew we had to act quickly and the council has helped us a lot. The improvement has happened very quickly.”
The list for action was based on inspections carried out by the council on behalf of the Food Standards Agency .
A council spokesman said: “The owner of Manzil takeaway has taken on board recommendations from the environmental health team and made improvements to his premises.
“This is part of a larger project involving around 40 previously low-rated premises.
“A number of businesses have already improved, and by the end of March we anticipate more previously poorly-performing food businesses to have taken advantage of the offer of guidance regarding how they can improve.”
