Nivalenol (NIV) Testing in Food and Feed

Nivalenol (NIV) is a Type B trichothecene mycotoxin produced primarily by Fusarium species, including Fusarium graminearum and Fusarium culmorum. These fungi infect cereal crops in the field, particularly under cool and wet conditions.
NIV is structurally related to deoxynivalenol (DON) and often occurs alongside DON and other Fusarium toxins in contaminated cereals.
It is most commonly associated with wheat, maize, barley and oats and may be present in both food products and animal feed manufactured from contaminated grain.

NIV contamination develops primarily during crop growth in the field. Climatic conditions such as prolonged rainfall and moderate temperatures during flowering significantly increase the risk of Fusarium infection and toxin production.
High-risk commodities include:
‣ Wheat and wheat-based products
‣ Maize and maize-based products
‣ Barley
‣ Oats
‣ Cereal-based feed ingredients
‣ Pet food formulations containing cereal fractions
NIV frequently co-occurs with DON and ZEA, particularly in cereal-based raw materials. Because co-contamination is common, single-toxin testing may underestimate overall exposure.

Like other trichothecenes, NIV inhibits protein synthesis and can affect rapidly dividing cells.
In animals, exposure may result in:
‣ Reduced feed intake
‣ Gastrointestinal irritation
‣ Impaired immune response
‣ Reduced growth performance
Although NIV is generally less studied than DON, it is considered toxic and contributes to the overall burden of trichothecene exposure.
In humans, chronic dietary exposure is controlled through monitoring and risk assessment due to its toxicological profile and potential long-term effects.
