Aflatoxin is a toxic and carcinogenic mycotoxin produced mainly by Aspergillus moulds on nuts, dried fruit and grains under warm, humid conditions, and is subject to maximum levels in EU food law.
In trade practice
Suppliers control aflatoxin risk through proper field drying, maintaining low storage humidity and segregating at-risk lots. Accredited laboratories test representative samples using HPLC or immunoaffinity methods before export. EU border authorities apply increased checks to consignments from origins with a history of non-compliance. A certificate of analysis covering aflatoxin B1 and total aflatoxins should accompany each shipment.
In a specification
A purchase specification typically states that aflatoxin B1 and total aflatoxins must not exceed the maximum levels set in Regulation (EU) 2023/915, with results confirmed by an accredited laboratory certificate.
