A Thai man was horrified after pulling a giant 10 metre long (32ft) tapeworm from his backside while using the toilet.

Kritsada Ratprachoom, 44, from Udon Thani in north eastern Thailand, was stunned when he felt something "sticking out of his bottom" and wriggling when he was using the bathroom.

At first the freelance photographer thought it was a piece of string leftover from the surgery he had had to have his appendix removed a week earlier.

However, he soon realised it was more than he'd bargained for - and the sticky and stretchy object was in fact a live tapeworm.

He said: "I had just finished dropping my child off at school and ran some errands when I had to go for a number two.

"Afterwards, I felt like I wasn't finished defecating, like something was left. So I got up to see what it was.

"Turns out there was something sticking out of my bottom."

Kritsada began pulling on the worm and said he felt like it could have been stretched for up to 32ft.

After pulling it out of his behind, the baffled man put the worm down on the toilet cistern and it began slithering around.

Perplexed with what to do, Kritsada proceeded to flush the worm down the toilet.

He is clueless as to how the worm could have got inside of him in the first place.

Tapeworms are flat, ribbon-like worms that can live in your gut if you swallow their eggs or small, newly hatched worms.

Tapeworm infections are rare in the UK, but are fairly common in other parts of the world.

Many don't cause obvious symptoms and can be easily treated.

But very occasionally, the worms can spread to other parts of the body and cause serious problems.

Tapeworms can grow up to 55ft long and can survive in the intestine as long as 25 years.
