Pots of posh vegetarian soup made by Prince Charles's brand Duchy Organic have been withdrawn because they were mistakenly filled with chicken and spelt broth.
Duchy Organic Spiced Carrot and Parsnip Soup sold by upmarket Waitrose at £2.99 a pot poses an allergy risk - as well as putting vegetarians off.
The chicken broth in the 600g soup also contains gluten and celery with none of the ingredients declared on the label.
The brand was set brand as a partnership between Waitrose and the Duchy Originals company, a company set up by Charles, Prince of Wales in 1990.
Waitrose said: "As a precaution, this product is being recalled, as a small number of pots have been incorrectly filled with Waitrose Duchy Organic Chicken and Spelt Broth.
"The Chicken and Spelt Broth recipe contains gluten and celery which are not declared on the label, making the product unsuitable for anyone with an allergy to gluten or celery.
"Any customers who have an allergy to gluten or celery, or are vegetarian, should not consume this product but return it to Waitrose for a full refund.
"We apologise for any inconvenience caused.
"For further information, customers should call Waitrose Customer Services Department on 0800 188884.
The Food Standards agency added: "Waitrose is recalling its Duchy Organic Spiced Carrot and Parsnip Soup with a use by date of 1 July 2016.
"A small number of packs have been incorrectly filled with Waitrose Duchy Organic Chicken and Spelt Broth, and therefore contains gluten and celery which are not mentioned on the label.
"This makes the product a possible health risk to anyone with an allergy to wheat (gluten) or celery.
"No other Waitrose products are known to be affected.
"If you have bought the above product and have an allergy to wheat (gluten) or celery, do not eat it. Instead return it to the store from where you bought it for a full refund."
