Expert explains whether wooden spoons are safe to use after people discovered amount of dirt inside

A science expert has explained whether it's actually safe to cook with wooden spoons after people discovered how much dirt they can hold inside.

They're a first-choice for a lot of people and they can last for years, but some users have been left horrified after soaking the spoons in boiling water and seeing dirt and cooking oil seep out of the wood.

“After all in the 1990s, people being worried about bacteria invading the porous surface, there was a big move away from wooden spoons into spoons made of steel, plastic, nylon or silicon," he continued.

Dr Karl went on to stress that 'wooden spoons are so lovely', pointing out they don't chip cooking pots, 'don't add flavour' and 'don't overheat'.

However, he continued: “So the bacteria story? Yes, the bacteria do exist.”

That doesn't mean the spoons aren't safe to use, though. Dr Karl continued: “The bacteria will invade the porous surface and they will go underneath the wood, and then, without nutrition, they just simply die."

“It’s just does not appear in the medical record that these things are a danger. So stir away.”

Dr Karl's assurance that the spoons are safe to use was met with delight by fans of the utensils, though of course it's still good to make sure the spoons are cleaned properly after being used.

Viewers shared their tips for cleaning the wood, with one writing: “I douse mine with white vinegar after plunging in hot water. I leave the vinegar for 20 minutes, give it a good rinse or soak in clean water - no odours."

Another suggested: "All one has to do is have a pot of boiling water and place the spoon in there for a minute or two, it will clean and sterilise the spoons.”

So it seems that as long as you're giving your spoon a decent clean after use, you don't have to worry about it being a health risk. And remember, just licking the cake batter off it doesn't count.
