If you're thinking of eating out this festive season, then there's probably something you should know.

This year alone, 97 restaurants in Croydon were given a 1 or a 0 after food hygiene inspectors from Croydon Council came knocking.

Now with the holidays nearly upon us and eating out becomes more commonplace, what you're eating is more important than ever.

“When planning where to go, residents and visitors can easily check hygiene ratings online and use that information to choose a restaurant for their Christmas party that takes food hygiene and safety seriously," Councillor Hamida Ali said.

“Christmas is an important time for local businesses.

"A good food hygiene rating is something to be proud of, and the vast majority of Croydon restaurants have a rating of three or above."

But the truth is, you can’t tell a restaurant’s hygiene standards by how clean and tidy the staff look, nor by how busy the place is.

Food inspectors work out hygiene ratings based on the handling of food, including preparation and cooking and storage, the cleanliness of facilities and how the business is managed.

The scheme works on a 0-5 ranking system, with 5 for establishments rated very good, 4 for good, 3 for generally satisfactory, 2 for improvement necessary, 1 for major improvement necessary and 0 for urgent improvement necessary.

Council also advised that if a green and black sticker is not displayed in the window, or a low rating is shown online, a better-informed choice can be made.

So we've done the hard work for you.

We've compiled all 97 eateries in Croydon that received a 1 and a 0 for their food hygiene rating in 2017.
