A MISTAKE in packaging could have had lethal results for a teenager with a deadly nut allergy.

If 15-year-old Carly Buckingham, of East End, North Leigh, had eaten a chocolate bar, which was almost included in her lunchbox, her throat would have swelled up and choked her.

Mum Angela Buckingham never buys nut products and chose caramel McVitie's Go Ahead bars for her daughter to take to school.

The two varieties of the bar, nut-free caramel crisp, and fruit and nut, are both sold in the same bright green outer packet.

Mrs Buckingham bought a pack of five bars, labelled Caramel Crisp, from Waitrose supermarket in Witney.

Due to an error in packaging, however, it actually contained fruit and nut bars.

Luckily, Mrs Buckingham spotted it before she gave Carly the potentially dangerous biscuit in her lunchbox. Now she is warning other mums, whose kids have a nut allergy, to watch out.

She said: "If some other little kid gets one put in their lunchbox, it could be nasty.

"The one thing that is really dangerous to Carly is nuts. They could cause a swelling of her throat if she eats them."

Tina Fotherby, McVitie's spokesman, said they were sincerely sorry. "McVitie's has launched a thorough investigation. One of the first things done was to check all of the other Go Ahead! products at the Waitrose store, none of which was incorrectly packaged.
