In an age where online shopping has become increasingly prevalent, ensuring accurate and comprehensive food allergen information is crucial for consumers. A recent study, funded by Campden BRI and published in Food Control, sheds light on the state of allergen labeling for Asian food products purchased online in the United Kingdom. The findings reveal a landscape where information can be lacking or inconsistently provided, posing potential risks to individuals with allergies or intolerances.

The study, which evaluated 768 prepacked products sourced from various Asian countries and purchased from eight UK retailers, including specialized Asian stores and major supermarkets, unearthed several concerning trends. Among the sampled products, 173 carried precautionary allergen labeling (PAL), with 24 different phrasings identified. PAL, although voluntary, aims to communicate the risk of unintentional allergen presence, yet the study found instances where non-EU and UK allergens such as mango, tomato, and beef were included in PAL statements.

Cereals and cereal products emerged as the category with the highest incidence of unintended food allergen presence declared through PAL. Furthermore, the study highlighted discrepancies in online allergen information. Of the sampled products, only a fraction emphasized or listed foods causing allergies or intolerances in bold type in online ingredients lists. Additionally, non-EU and UK food allergens were emboldened in online product information in only two cases, indicating a lack of consistency in providing comprehensive allergen information online.

Verification of online product information against on-pack product labels revealed troubling inconsistencies. Thirty-six products exhibited inconsistencies between on-pack and online allergen information, while 15 were completely mismatched. Some products did not emphasize any allergens online despite listing them on the pack, while others provided different allergen information online compared to on-pack labeling.

Laboratory analysis further underscored the potential risks associated with inaccuracies in allergen labeling. Of the products tested for milk and peanut allergens, 24 contained unintended allergens, with levels ranging from 0.2 to 6,780 mg/kg. These findings emphasize the importance of robust food allergen management and safety practices within the food industry.

In response to these findings, researchers stress the need for food businesses to adopt and implement more stringent allergen management protocols. Ensuring consistency and accuracy in allergen labeling, both online and on-pack, is imperative to safeguarding consumer health and well-being. Moreover, regulatory bodies and industry stakeholders must work collaboratively to establish and enforce standards that prioritize the safety of individuals with food allergies or intolerances.

As consumers increasingly turn to online platforms for their food purchases, it is essential that they have access to reliable and transparent allergen information. By addressing the shortcomings identified in this study, the food industry can take proactive steps towards fostering a safer and more inclusive food environment for all consumers.
