The Scoff Standards Agency ordered the 235ml bottles to be recalled after the equipping was found to contain egg, despite it not being declared on the ingredients list.
An FSA spokesman implied: “The supplier of Mary Berry’s Salad Dressing has identified that another goods with egg as an ingredient has been filled and labelled as the above product.
“This cuts it unsuitable for people with a sensitivity to egg. As a precautionary measure, the product is being disowned.”
The FSA said people with a sensitivity to eggs should call 01494 895507 to plan for a replacement to be sent out.
Consumers can also return the dressing to supermarkets for a blazing refund.
A spokesman for distributor RH Amar said: “Whilst we deeply deprecate the inconvenience caused to consumers, we remain confident of the production controls in bring down at our manufacturing site.
“We are carrying out a full internal investigation.”
