What did the investigation find?

The investigators took five swabs from different locations in ten fridges. These were:

The report states: “You introduce new microbes into the fridge every time you unpack groceries, so we weren’t surprised to find that every fridge was teeming with bacteria.”

“These germs are linked with respiratory and urinary infections, especially for people with existing health problems or weakened immune systems,” the report said.

These bacteria can cause “food-borne illnesses and a range of infections, from skin conditions to sepsis” the report said.

It continued: “They’re likely to have come from unwashed vegetables, highlighting the importance of cleaning your fridge regularly.”

Failing to keep your fridge at the correct temperature, and not cleaning it frequently enough are two of the main reasons that harmful bacteria thrive.

How to keep my fridge safe?

According to the Food Standards Agency (FSA), a fridge should be kept between the temperatures of 0°C and 5°C.

“Chilling food properly helps stop harmful bacteria from growing,” the FSA explains.

The best way to check the temperature of your fridge is by using a fridge thermometer.

The FSA says: “This is because the dials on fridges don’t always show you the right temperature.”

“More than four in ten of the fridge freezers we’ve tested have a default or recommended setting that’s either inaccurate or unreliable,” Which? reported.

The coldest part of your fridge should register below 5°C.
