Britain's filthiest takeaways can today be named and shamed in our astonishingly detailed interactive map.

A Daily Mail audit of Food Standards Agency (FSA) hygiene ratings revealed 3,600 outlets were so dirty they failed inspection.

Nationwide, it means one in 17 takeaways and sandwich shops fall below minimum standards. 

Some 175 outlets scored zero – the worst possible rating. Among them were Indian and Chinese takeaways, kebab shops, pizza joints, burger bars and chippies. All of them were told that 'urgent improvement is required'.

Inspectors have found rotting food, rodent droppings, insect infestations at some of the worst-offenders, while others have been scolded after being caught storing raw chicken dangerously.

In England, Wales and Northern Ireland, all venues serving food are judged on a scale between zero and five. 

Scores of two or below are counted as a fail. 

The Mail's probe discovered 1,560 had a rating of two, with the FSA warning them that 'some improvement is necessary'.

Another 1,240 scored one – meaning major improvement is necessary.

Out of a total of 63,500 outlets nationwide, it means 5.7% failed.

FSA research found it is twice as likely for foodborne illness outbreaks to occur in zero, one or two rated businesses than in those that are rated three, four or five. 

Venues in Scotland are graded on a binary pass/fail basis.

Mail analysis found 660 businesses were slapped with an 'Improvement Required' label.

In the most serious cases, officers can close a business until improvements are made and can also recommend that a firm be prosecuted for breaching food standards regulations. 

Broken down by local authorities, the worst offender was the Scottish Borders with 26% of takeaways failing inspection, followed by Aberdeen (25%) and Pendle (20%).

However, at the other end of the filthy scale, 31 councils didn't have a single outlet that failed a hygiene rating.

An inspection fail can devastate businesses, damaging their reputation permanently overnight.  

Some delivery platforms, such as JustEat, require a minimum rating of three to register. And if the rating drops to a zero, they are immediately removed from the app.

Consumers are now far more aware of food hygiene ratings than ever before, Food Safety Consultancy UK. 

A spokesman told the Daily Mail that more people are now regularly checking ratings online, and local community Facebook groups can highlight poor scores very quickly.
