Costa Coffee has been forced to pull its Chicken and Bacon Pasta Salad because it contains fish, milk and mustard that are not mentioned on the label.
The £3.99 salad, launched this month as part of the chain's new summer menu, may pose a risk to those allergic to milk and dairy products.
If eaten by allergy sufferers, they could go into anaphylactic shock - which can be fatal without urgent medical treatment.

The Food Standards Agency (FSA) announced the recall on products with the use-by date of May 22.
In a bulletin it said: 'If you have bought the above product, do not eat it. Instead, return it to the store from where it was bought for a full refund.'
A Costa spokesperson said: 'Costa Coffee is recalling its Chicken & Bacon Pasta Salad with a use by date of May 22 due to a product labelling error of undeclared allergens; fish, milk and mustard.
Anaphylaxis, also known as anaphylactic shock, can kill within minutes.
It is a severe and potentially life-threatening reaction to a trigger, such as an allergy.
The reaction can often be triggered by certain foods, including peanuts, dairy products and shellfish.
However, some medicines, bee stings, and even latex used in condoms can also cause the life-threatening reaction.
According to the NHS, it occurs when the immune system overreacts to a trigger.
