The husband of a woman who died after eating a Pret a Manger wrap has told an inquest of the harrowing moment she collapsed in the street, unable to breathe.

Celia Marsh, 42, a dental nurse from Melksham, Wiltshire, died on December 27 2017 after eating a super-veg rainbow flatbread from the sandwich chain’s store in Bath, Somerset.

The wrap contained yoghurt which was labelled vegan but was later found to have traces of dairy protein in it.

The mother-of-five suffered from a severe dairy allergy and “religiously avoided” all dairy products following a near-fatal allergic reaction months earlier.

Mrs Marsh had been on a post-Christmas shopping trip with her husband and three of her daughters when she went into Pret to buy something to eat.

In his statement, which was read to the hearing by the coroner’s officer, Andy Marsh said his wife had begun to feel “a bit funny” after eating the wrap, while they were in the clothing store Gap, and they decided to leave the shop.

He said: “We started walking down the narrow side street by the Gap store and Celia had her asthma inhaler out.

“She used it a couple of times and I asked her if she was OK.

“She said she was struggling to breathe but it may be because of the cold air.

“We then moved to a small side street on the left and I pulled her to one side.”

He said Mrs Marsh had initially thought she was “being silly” because the sandwich had been labelled “vegan”.

“She had her Epipen in her hand and I said to her that if she thought there was any chance she was having a reaction that she should just do it and use the pen as it doesn’t matter,” he said.

“She then said to me 'You need to phone an ambulance',” he added.

Mr Marsh said he phoned 999, by which time his wife had collapsed and was being tended to by an off-duty GP who had offered to help.

“They took Celia away in an ambulance but I had my children with me so could not go in the ambulance with her to the hospital,” Mr Marsh said.

“I was really in shock so it took a short time before I was able to drive up to the hospital in my car."

When they later arrived at the hospital, they were taken into a side room and were told that Celia had been pronounced dead.

Mr Marsh and his daughters could be seen weeping during the hearing as the statements were read out.

An allergy specialist from Southmead Hospital, Dr Nikolas Tsiougkos, also gave evidence about the seriousness of Mrs Marsh’s condition.

The inquest is taking place at Ashton Court Mansion House in Bristol and is expected to last between two and three weeks. It will determine how Mrs Marsh died.
