Pret A Manger: Yoghurt producer weeps at Celia Marsh inquest

Celia Marsh died in 2017 after eating a super-veg rainbow flatbread labelled as vegan

The manufacturer of the supposedly dairy-free yoghurt used in a Pret A Manger wrap eaten by a woman with a severe allergy broke down in tears at her inquest.

Celia Marsh went into anaphylactic shock and died in the centre of Bath, shortly after eating the food.

The yoghurt produced by Planet Coconut contained starch supplied by Tate & Lyle PLC, the inquest heard.

The starch was identified as the possible source of the contamination.

Mrs Marsh, a 42-year-old mother of five, from Melksham in Wiltshire, died on 27 December 2017 despite the efforts of passers-by and paramedics to save her.

A chemist who analysed the wrap previously told the inquest he believed it contained milk.

Planet Coconut is the UK manufacturer and distributor of products developed by Australia-based yoghurt company CoYo.

Bethany Eaton, the managing director of Planet Coconut, broke down in tears as she gave evidence at the inquest at Ashton Court, Bristol.

Mrs Marsh's husband Andy said his wife "religiously" avoided dairy

She told the hearing she had set up Planet Coconut with her husband in 2011 to manufacture dairy-free products and purchased a licence from CoYo founder Henry Gosling for exclusive UK rights.

"Dairy-free is something I am passionate about which is why we bought the CoYo licence," Ms Eaton said.

"I didn't ever dream it would contain dairy after he (Henry Gosling) sold me a licence.

"He said it was made in an allergen-free environment. He had a very good relationship with Tate & Lyle."

Celia Marsh brought the wrap from a Pret A Manger branch in the centre of Bath

Maria Voisin, the senior coroner for Avon, asked Ms Eaton whether she considered testing the starch.

She replied: "We never tested the product because I was assured and believed it was being made in an allergen-free environment.

"I was told there was a separate line or facility that was entirely allergen-free and that's what we relied upon."

She said that since Mrs Marsh's death all products are now tested, irrespective of the source.

"I regret buying a licence and trusting the word of someone else," added Ms Eaton.
