About

What it is and where it shows up.

Pistachio powder is finely ground dried pistachio nuts (Pistacia vera), used as a flavouring, colouring, and nutritive ingredient in confectionery, baked goods, ice creams, and savoury dishes. It imparts a characteristic green colour, rich nutty flavour, and contributes protein, healthy fats, and micronutrients to food products.

Safety summary

The regulatory and scientific consensus.

Pistachio powder is safe for the general adult population when sourced from properly processed, aflatoxin-controlled nuts; no ADI has been established as it is a whole-food ingredient rather than an additive. The primary food-safety concern is aflatoxin contamination: regulatory bodies including the FDA (action level 20 µg/kg) and EFSA (maximum level 4 µg/kg total aflatoxins) set strict limits, as aflatoxins are genotoxic and carcinogenic. Additionally, pistachio is a recognised tree-nut allergen capable of triggering IgE-mediated hypersensitivity reactions, including anaphylaxis, and shows cross-reactivity with cashew nut and mango.

Regulatory landscape

What food-safety regulators have decided.

Jurisdiction	Status	Note
FSANZ (Food Standards Australia New Zealand) (Australia)	Approved	Pistachio products, including nut flour and ground pistachio, are regulated food ingredients. FSANZ maximum level (ML) for aflatoxin in pistachios is 0.015 mg/kg (15 µg/kg), applying to both imported and domestically produced commodities. Tree nuts including pistachios are mandatory allergen declarations under the Australia New Zealand Food Standards Code.source
EFSA (European Food Safety Authority) (European Union)	Approved	Pistachio and pistachio-derived products are permitted food ingredients. EU maximum level for total aflatoxins in pistachios intended for direct human consumption is 4 µg/kg (AFB1 limit: 2 µg/kg) under Regulation (EC) No 1881/2006. EFSA concludes aflatoxin exposure should be kept as low as reasonably achievable. Pistachio nut is listed as a mandatory allergen requiring declaration under Annex II of Regulation (EU) No 1169/2011.source
FSSAI (Food Safety and Standards Authority of India) (India)	Approved	Pistachio nuts and derived products are permitted. FSSAI Food Safety and Standards (Contaminants, Toxins and Residues) Regulations 2011 set aflatoxin limits for tree nuts. Tree nut allergy labelling is required under FSS (Labelling and Display) Regulations 2020.source
FDA (Food and Drug Administration) (United States)	Approved

Who should approach with care

Whose guidance would steer them away.

Nut Allergy — Pistachio is a recognised tree nut containing multiple IgE-binding protein allergens capable of triggering severe type I hypersensitivity reactions, including anaphylaxis, and shows cross-reactivity with cashew nut and mango; individuals with tree-nut allergy must strictly avoid pistachio powder.

Infants — Pistachio allergy can develop in infants via breast milk if the mother consumes pistachios; introduction of pistachio powder to infants should follow medical guidance and age-appropriate allergy introduction protocols.

Lactation — Maternal pistachio consumption can transfer allergens through breast milk and cause allergic reactions in breastfed infants, particularly those with emerging tree-nut sensitivity; lactating mothers with a family history of nut allergy should consult a doctor.

Liver Disease — Aflatoxin contamination, a known risk in pistachio products, is hepatotoxic and carcinogenic; individuals with pre-existing liver disease may be at heightened risk from any aflatoxin exposure and should ensure pistachio powder is sourced from rigorously tested, compliant suppliers.
