Cadbury Dairy Milk Contains Milk

Apparently, the name is not enough of warning. Nor is the logo: an image of glass-and-a-half of milk being poured into a chunk of chocolate.

Cadbury Dairy Milk wrappers put milk first in a list of ingredients and explain that there is "the equivalent of three quarters of a pint of fresh liquid milk in every half pound of milk chocolate".

However, Cadbury says it is also necessary to print warnings saying "CONTAINS: MILK" in case people who are allergic to milk do not realise that there is milk in Cadbury Dairy Milk.

The company is printing similar warnings on bars of Cadbury Dairy Milk Whole Nut.

A Cadbury spokesman said the company was complying with the law relating the presence of allergens in food.

But even a support group for people who are allergic to certain foods said Cadbury was going beyond the requirements of the law.

Moira Austin, helpline manager for the Anaphylaxis Campaign said she could understand why people would say Cadbury was "stating the blindingly obvious" or think that the "world had gone mad".

She added: "The law requires manufacturers to list allergens if they are an ingredient. It does not require these additional warnings.
