Evaluation of Label Compliance to Allergens in Imported Asian Food Sold in Northern Italy

Abstract Background The import of Asian food is strongly increasing in the EU. In Italy, the Asian market has expanded over the last 3 decades. Unfortunately, the labelling of these products often implies errors, mainly due to linguistic differences. Consequently, it can become a consistent problem regarding food safety, in particular for allergens declaration. According to EU Reg. 1169/2011 (Annex II), allergens must be labelled in bold and translated in the current language of the Member State. Asian food non-compliant labelling could enhance the probability of allergic consumers to get adverse events; accordingly, it is important to increase controls on the imported products. The present work investigates the label compliance to allergens on Asiatic products imported in Northern Italy. Methods Totally, 39 foodstuffs were tested for gluten, 93 for white egg proteins and 118 for milk proteins by commercial ELISA kits according to manufacturers’ instructions. Samples were considered non-compliant when the results were above 20 mg/Kg, the law limit for gluten, or above the milk LOD (10 µg/Kg) and the egg LOD (0.4 mg/Kg). Results Data showed 18% (CI 95% 0.09-0.32) of non-compliant samples for gluten: 6 samples > 80 mg/Kg (snacks and ready to eat meal) and 1 sample containing 48 mg/Kg (snack). In addition, 19.4 % (CI 95% 0.13-0.28) showed presence of egg proteins (noodles, snacks, patties and pasty). Finally, 13.6% (CI 95% 0.08-0.21) samples were irregular for undeclared milk (noodles and snacks). Conclusions Products label report their content and represent an important element for food trading and tracing. The results obtained confirm a high percentage of non-compliant labels, underlining how the consumption of imported products can represent a health risk for allergic consumers. The present work highlights the importance of imported food monitoring to guarantee the consumers health, and of the implementation of standardized/international regulated labelling rules. Key messages • Many non-compliant labels about allergens was observed on Asiatic products. • Correct labelling of allergens in imported food should be monitored to avoid adverse events.
