Why Allergen Labeling for Nuts is Critical
Nut allergies can cause severe, life-threatening reactions, such as anaphylaxis, making clear and accurate food labeling a vital public health measure. Regulatory bodies worldwide establish lists of priority allergens that must be declared, giving consumers the information they need to avoid dangerous foods. While the specific nuts included on these lists share many common members, regional differences exist that can be crucial for consumers and manufacturers to understand.
Understanding the Difference: Peanuts vs. Tree Nuts
One of the most important distinctions in allergen labeling is between peanuts and tree nuts. Despite their name, peanuts are legumes that grow underground, related to beans and lentils. In contrast, tree nuts are a distinct group of actual nuts that grow on trees, including almonds, walnuts, and cashews. Due to these botanical differences and distinct allergenic proteins, regulations generally categorize and declare them separately.
US Regulations: The FDA and FASTER Act
In the United States, the Food and Drug Administration (FDA) enforces allergen labeling rules under the Food Allergen Labeling and Consumer Protection Act (FALCPA), updated by the Food Allergy Safety, Treatment, Education, and Research (FASTER) Act. This requires the specific type of tree nut to be declared.
Tree Nuts Declared by the FDA
As of recent guidance in 2025, the FDA has specified a list of tree nuts that must be declared on food labels.
- Almond
- Black walnut
- Brazil nut
- Cashew
- English and Persian walnut
- Filbert/Hazelnut
- Heartnut/Japanese walnut
- Macadamia nut
- Pecan
- Pine nut
- Pistachio
- California walnut
FDA Exclusions
It is notable that some items often considered nuts, like coconuts, have been explicitly excluded from the FDA's mandatory labeling list for tree nuts. Other examples of items removed from the official declaration list include beech nut, butternut, and chestnut.
European Union Regulations: EU FIC Annex II
The European Union operates under the Food Information to Consumers (FIC) regulation (EU Regulation No 1169/2011), which requires the declaration of 14 major allergens, including specific tree nuts.
Tree Nuts Declared in the EU
The EU mandates the declaration of the following specific nuts when present as an ingredient:
- Almonds
- Hazelnuts
- Walnuts
- Cashews
- Pecans
- Brazil nuts
- Pistachios
- Macadamia or Queensland nuts
Australia and New Zealand: Food Standards Code
In Australia and New Zealand, the Food Standards Code dictates allergen labeling requirements. Recent changes emphasize clearer labeling and separate declaration of individual nuts.
Declared Nuts in Australia and New Zealand
The required list includes:
- Peanuts
- Almond
- Brazil nut
- Cashew
- Hazelnut
- Macadamia
- Pecan
- Pistachio
- Pine nut
- Walnut

Labeling Practices and Precautionary Statements
Manufacturers must clearly declare regulated nut allergens in the ingredients list, typically emphasized with bold, capital letters, or a contrasting background. However, manufacturers may also use voluntary "may contain" or "may be present" statements, known as precautionary allergen labeling (PAL). This indicates a risk of unintentional cross-contamination during production. It is important to note that PAL statements are not legally regulated, and their use is based on the manufacturer's risk assessment.
Conclusion
The regulation of nut allergens is a complex, yet crucial, aspect of global food safety. While there are common nuts, such as almonds, cashews, and walnuts, that are nearly universally regulated, regional variations exist that can impact consumer choice and safety. For those with nut allergies, a deep understanding of what nuts are declared under regulations in their specific region is essential for safe food consumption. Reading labels carefully, understanding the difference between peanuts and tree nuts, and knowing how to interpret both mandatory and precautionary statements are key steps in managing dietary restrictions. As regulations evolve, staying informed through official sources like the FDA is the best practice for ensuring safety.
