A mum-of-three was left stunned after finding a false-widow spider in a punnet of grapes she was about to feed her children.
Emma Deeks, 32, decided to feed her sons Jack, 8, Harry, 5 and Charlie, 22 months, some healthy grapes for a snack.
Emma, who lives in Chinnor with husband Matt, 33, said: “I went to take the grapes out of the fridge, which is where I keep them, and as I picked up the punnet I saw something move.
“When I saw the the spider I trapped it in a pot and put it outside because I didn’t want it in the house.”
Though she bought the grapes in Sainbury’s in High Wycombe, head office advised her to take the beast to the Thame branch where it would be couriered to Sainbury’s headquarters.
After some online research, Emma discovered the spider was a Steadota Nobilis, also known as a noble false widow.
Despite its intimidating appearance, the creature is not poisonous but its fangs can give a painful bite.
It is native to the UK, Ireland, France, Spain and Portugal – the latter being where Emma’s grapes had been imported from.
She said: “I dread to think what could have happened if my boys had been getting their own snack.
“It makes me cringe just thinking about it.”
A Sainsbury’s spokesman said: “Incidents like this are extremely rare and we have apologised to Emma.
“All of our growers have a range of checks in place to minimise the presence of insects in grapes including routine inspection prior to packing.”
