Hazelnuts are the edible seeds of a tree belonging to the birch family, often cultivated for their rich flavor and high nutritional value. While the fruit of the hazelnut tree is also a drupe, encased in a hard shell, hazelnuts are considered major tree nuts that can cause severe food allergies. Cross-contamination can occur during manufacturing, making it essential to monitor both the production environment and food products for hazelnut traces. The food industry must utilize highly sensitive testing equipment to ensure compliance with stringent food safety standards.
Mandatory labeling of tree nuts in food products
Tree nuts, including brazil nuts, are among the most frequent causes of food allergies. In Europe and the United States, the prevalence of tree nut allergies as a whole is estimated to range between 0.2% and 0.5% in both children and adults. To protect consumers from the potentially fatal consequences of Brazil nut consumption, allergen labeling is required by law in many countries. Brazil nuts, along with other tree nuts, are regulated in the EU (Regulation (EU) No 1169/201) and the US (U.S. FDA – FALCPA 2004).
