There’s a ‘hidden’ button in your fridge that can help keep your food fresh for longer, but many Brits often overlook it.

Have you ever forgotten about something in your fridge and found it mouldy? Well there’s a secret button that can stop this from happening.

This button is in all fridges, but many people don’t notice it. But if you set it right, your food will last longer.

The secret switch is the temperature button, usually inside the fridge. It’s one of the best ways to keep your food fresh for longer, reports the Mirror.

It has numbers from zero to five – but do you know what they mean?

These numbers set your fridge’s temperature – but they don’t always match the actual coldness in degrees Celsius. Instead, they show the fridge’s power – with five being the coldest.

The Food Standards Agency says fridges should be set at 5C or lower. Anything over 8C can make bacteria grow fast on your food, so it won’t last as long.

The best setting depends on the fridge maker, which you can find in the instruction manual.

Which? suggests that the perfect temperature for your fridge is between 0C and 5C. To find out the exact temperature inside your fridge, put a thermometer in a glass of water and place it on the middle shelf.

It’s best to leave it there overnight for an accurate reading. Remember, even if your thermostat is spot on, the temperature can change from shelf to shelf. The higher the shelf, the warmer it will be – so think about where you put different items.

Put cured meats, leftovers, cream cakes or anything else that doesn’t need cooking on the top shelves. Keep raw meat, poultry and seafood on the bottom shelves, and fruit and vegetables in separate drawers.
