Jan Bogusz says he found a bug in a packet of Whitworths Semolina.
AN electrician says he was 'shocked' to find a live moth and its empty chrysalis inside a packet of semolina.
Jan Bogusz, of Ermine East, told the Echo he discovered the moth flapping its wings in an agitated fashion after his daughter opened a new packet of Whitworths Semolina.
Initially thought to be some kind of winged beetle, Mr Bogusz believes the 1cm creature, complete with its hibernating shell, was sealed inside the clear plastic packaging before being boxed up and sent for sale, possibly while it was still a tiny egg.
Whitworths has now apologised to Mr Bogusz, but added the "highest standards" of quality control are put in place with all its products.
"I heard my daughter screaming that there was something in the semolina, but I never expected it to be anything like this," said Mr Bogusz, an electrician.
"I don't believe that it got in there after being packed up; there are no holes in the bag. I was amazed it was alive.
"I'm not after any kind of compensation and I don't want to have some Whitworths products sent over to me, I just thought it was something that needed bringing to people's attention."
Mr Bogusz says he discovered the moth on Wednesday last week. The semolina had been bought at Asda two months previously, but never opened.
Whitworths spokesman Martin Jackson said the product was going to be investigated.
"We would like to thank Mr Bogusz for bringing this matter to our attention and apologise for any inconvenience caused," he said.
"We apply the very highest standards of quality control throughout all our production processes and, assuming that this matter be traced back to us, will immediately look into how an isolated incident of this nature could have occurred.
"We are taking this matter extremely seriously and have called the product Mr Bogusz purchased in for investigation."
Experts from Lincolnshire Wildlife Trust examining photographs confirmed it is a rice moth – something which is partial to any dried food and often found in imported goods.
Rachel Shaw from the Lincolnshire Wildlife Trust said: "The insect pictured is a rice moth Corcyra cephalonica.
"The caterpillars of these moths feed on a wide variety of things including stored foods such as grain, flour and cereals. It's always a good idea to keep food in well sealed containers to ensure you don't get them in your pantry.
"It may have occurred in this case, by accidently getting into the food as an egg or caterpillar."
Asda were unavailable for comment.
