This is the stomach churning moment a woman found dozens of worms inside a pack of celery from a Kent supermarket.

Benjapan Sage bought two bags of celery from Sainsbury's in Maidstone as she was planning to make a green smoothie at home.

But while she was preparing the vegetables - one day after the best before date - the disgusting creatures were found in the bowl of water.

In footage filmed by the 35-year-old, dozens of transparent sites can be seen wriggling around in the bowl.

Benjapan, a photographer, said she tried three times to clean the celery but ''more kept worms coming out''.

Sainsbury's later apologised and refunded the shopper by giving her 1,000 Nectar points.

Benjapan, who is from Thailand but has lived in the UK for seven years, said: "There were a lot of these horrible little worms when I washed the celery the first time, so I washed again with a brush but more of them kept coming out."

After being sent the video of the worms in the celery, Sainsbury's said to the customer in a message: ''Sorry about that. Can you send me a picture of the barcode and let me know which store you bought this from.

''I've popped 1,000 Nector points (£5) into your account today which will arrive within 72 hours. I've also logged this info for review with the store. Hope this helps. Adam.''

Disappointed Benjapan added: "I like to put celery in my drink, so I buy it quite often. But this was the first time I bought it from Sainsbury’s and it was in this condition.

"I hope the store will be more careful when choosing the fresh fruits and vegetables because anything could be hiding inside them and be harmful to customers."

A Sainsbury's spokeswoman said: "We’ve apologised to the customer for this unpleasant find.

"This type of problem is extremely rare and we work closely with our suppliers to prevent this from happening.”
