Evaluation of food allergen information, labelling and unintended food allergen presence in imported prepacked foods and drinks purchased online in the UK

Consumers have wide access to global food and drink products online and in store that require food allergen information and labelling. Frequent food and drink product recalls occur UK and worldwide due to incorrect labelling of food allergens and their unintended or undeclared presence. This research aims to evaluate the accuracy and compliance of information and labelling of substances or products causing allergies or intolerances in prepacked food and drink products imported from Asia and purchased online in the UK. The current study assessed 768 randomly selected prepacked products classified into 16 separate product categories, representative of items from 12 countries in Asia, sourced from 8 UK retailers. When screened for precautionary allergen labelling (PAL), 173 (22.5%) items provided PAL, with 24 phrasings being identified. Upon comparing food allergen information on pack and online, 36 products (36.0%) transferred inconsistencies on pack to online pages and 15 (15.0%) were not consistent. Additionally, laboratory studies were performed to detect milk and peanut allergens in a sub -group of 77 products. Following analysis, 24 (31.2%) contained unintended food allergens, with levels ranging from 0.2 to 6780.0 mg/kg. Of these items, 9 products (37.5%) had a risk ratio >= 1 exceeding action levels produced with the VITAL (R) 3.0 ED01 reference doses, recommending PAL, though 7 (29.2%) were found without PAL. A further 10 products (13.0%) overused PAL and 2 products (2.6%) used PAL correctly. This research indicates further refinement of policies to ensure adequate, accurate, clear and current food allergen information and labelling of products.
