JRC scientists investigated the suitability of immunoaffinity columns for the determination of masked (modified) mycotoxins, a class of food contaminants currently being discussed for EU regulation. The study focused on the mycotoxin deoxynivalenol (DON) and its metabolites which can frequently occur in cereals.
Masked (also called modified) mycotoxins have been recognised as important contributors to the toxicological hazard deriving from fungal spoilage of agricultural products. DON is the most frequently detected trichothecene (mycotoxin) in cereals and is occurring together with its derivatives in highest amounts compared to other mycotoxins. European legislation sets maximum limits for DON in a variety of agricultural products, while the Commission as well as Codex Alimentarius aim for and discuss a health based maximum limit for all derivatives of DON. It is therefore important to detect and quantify all forms of DON to not underestimate the toxic potential of a particular food or feed consignment.
