Mycotoxin Outlook for 2026 Harvest – Part 2

The September edition of The Digest set the foundation for this article by outlining the various mycotoxigenic molds and the factors that drive mycotoxin production. At the time of writing, a limited number of 2026 corn grain samples were screened as part of our PROcheck mycotoxin analytical service. The author anticipates that we’ll have more results in time for the November issue of The Digest and be able to compare actual contamination data vs. this month’s predictions. Read the full article to learn what mycotoxins we expect in 2026 corn!

Mycotoxin Outlook for 2026 Harvest – Part 1

The 2026 corn growing season in North America yet again provided extreme weather events including record high temperatures and excessive rainfall in some places while others are experiencing severe drought conditions. Many factors influence the risk for mycotoxin contamination in crops, but climatic conditions play a critical role. While maximizing yield is often the goal, considerations for crop condition are also important heading into harvest. This article will provide an overview of major mycotoxigenic molds and key factors which influence the production of mycotoxins in corn. This will set the basis for next month’s article which will dig deeper into what contamination profiles might look like with the 2026 corn crop.

Mycotoxin biomarkers - is the hype justified?

Despite the challenges which exist with mycotoxin analysis of feedstuffs, feed analysis continues to be the widely accepted way to monitor mycotoxin risk. An alternative approach which has garnered attention in recent years is the use of mycotoxin biomarkers – assessing mycotoxins via analysis of blood or other biological matrices (urine, bile, etc.) collected directly from animals. Although the use of biomarkers sounds like an exciting way to evaluate mycotoxin risk, there are also various limitations to consider. This article will provide insights into the use of mycotoxin biomarkers and highlight some of the current key challenges with this approach.
