Preamble

The occurrence of mycotoxins in agricultural commodities has significant ­implications for the health of the consumer. Because of this, many countries have introduced regulatory limits for various mycotoxins in a range of products. Adherence to these limits is important to safeguard the consumer and also to permit trade in the affected commodities across international borders. Effective schemes to test for the presence and concentration of mycotoxins depend not only upon sound analytical methods, but also on sampling plans designed to ensure that the results of analysis of laboratory samples reflect, as accurately as possible, the overall concentrations in consignments or lots of produce, and to provide a good estimate of the variability or uncertainty associated with the analytical results. The results can
