A spokesman for Tesco said: “We were concerned to learn of this issue and have launched a thorough investigation with our supplier. We have apologised to her and will of course keep her updated with the findings.”
The shopper, 31-year-old Claire Katoroz said she vomited after finding the moving insect in her sandwich.
‘It sprung out and started moving’
“I decided to take the lettuce out, as a friend of mine once found a snail inside a bag of lettuce, Katoroz told the Hastings and St Leonards Observer. “I spotted the caterpillar after it sprung out and started moving.”
Meanwhile, last month the supermarket giant apologised to two shoppers who discovered maggots in a box storing Cadbury’s Caramel Nibbles in a store in Sunderland.
Speaking at the time, a spokeswoman for Tesco said the area of the store concerned was cleaned regularly and filled with new products. “We are conducting a full investigation and will involve the police if necessary,” she said.
