The Missouri Department of Agriculture is happy again to report the results on our annual monitoring of aflatoxin in corn. This survey has been reported yearly since 1993. We also analyze all customer complaint samples for aflatoxin when symptoms suggest adulteration. Laboratory tests are conducted to determine the average crude protein in corn. In 2016, the average crude protein for corn was 7.38%, higher than 6.94% in 2015’s corn crop. Each sample was adjusted to a 13.5% moisture level.

Samples of corn are drawn from counties having an expected production of greater than 1.5 million bushels, with one sample added for each additional two million bushels produced. 211 samples were tested for alfaxotin. Only three positives were found; one below 20 ppb and two in the 50-99 ppb range.

The Missouri Department of Agriculture is committed to food safety and quality for the protection of our state’s consumers. Our mission is to continue to serve, promote, and protect the agriculture producers, processors and consumers of Missouri food, fuel and fiber products.
