The prevalence of mycotoxins in grains is usually associated with the occurrence of the causal organism for example the filamentous fungi fusarium and related causal factors, such as temperature and moisture. To minimize human exposure to contaminated grains regulatory agencies have established advisory levels, guidelines and regulations for various commodities and foods. The maximum limits (MLs) should be adequately protective of health yet also practically achievable so that trade disruptions do not occur.<br>
<br>
In response to the proposal at the Codex Alimentarius Committee on Contaminants in Foods (CCCF) to lower the MLs for deoxynivalenol (DON, vomitoxin) in cereals a series of international discussions by both cereal grains and mycotoxin experts were started. These discussions provided the basis for a recent AACCI and NAMA led study. The study was published early in 2015 and the key results of the study were presented as comments to the 9th session of CCCF in March.<br>

In agricultural commodities, the occurrence of DON has been reported globally, with levels varying among grain types and years of production. The grain supply chain, including growers, buyers, and end users, have effectively managed DON with strategies to control this issue systematically. The safety of consumers is ensured through use of these management strategies.<br>

The last year has seen governments around the world consider the balance between the toxicological /human health aspects in different population groups and the availability of sufficient good quality cereal grains. The impact of the proposed Codex ML’s has raised questions regarding availability of specific grains, in particular for soft wheat-based products in North America and for trading partners
