Taken from The Food Standards Agency:
Current allergen labelling rules will be changing on 13 December 2014.
However, many businesses are already starting to make changes to how they label allergens on their products.
Under the new rules, allergens will be emphasised on the label. Food businesses can choose what method they want to use to emphasise these, for example, by listing them in bold.
Other types of emphasis may be used as well, such as italics and underlined or highlighted words. Some companies may also emphasise the whole word for example: wheatflour or use the words ‘from milk’ after listing the ingredient cream.
Please note, that the new rules will mean that a ‘contains x’ allergen statement can no longer be provided for food alongside an ingredients list.
