Essentially, official recommendations have been made that restaurants should label all ingredients in the meals they serve. For example (from the BBC News story here):
Supermarket sandwich: already has to list full ingredients including allergens
Over-the-counter sandwich: if it’s made to order in front of you, it doesn’t currently need a label. This will not change under the new plans.
Pre-prepared sandwich: if it is made on the premises, it doesn’t currently need a label, just a sign nearby prompting customers to ask about allergens. But if these recommendations are adopted, any sandwich that is wrapped and picked from a shelf will need to carry a label listing all ingredients, and highlighting major allergens
I think that is an excellent idea, especially for those of us with non-14 allergen issues as all ingredients will need to be labelled.
Rather than reinvent the wheel, here is What Allergy? blogger Ruth waxing lyrical on it. I certainly recognise how she feels about safety and eating out, note my comment after the article. Let’s hope the recommendations are taken up and implemented. Fingers crossed.
