Romer Labs, Inc. Analytical Services in Union, MO is converting dsm-firmenich customers using mycotoxin analytical services from the existing multi-mycotoxin LC-MS/MS method (24003000S023) to the updated LC-MS/MS PLUS method (24003000S034). The PLUS method features workflow improvements as well as enhanced sensitivity and has been implemented on samples received by the lab as of August 1, 2023. The following changes are expected as part of the updated PLUS method analysis:

The September issue of The Digest included an overview of factors which influence the presence of mycotoxins in crops to help provide the rationale behind the 2024 corn crop mycotoxin predictions which will be revealed in this issue. A limited number of new crop samples have been submitted for analysis through our PROcheck mycotoxin testing service to date, so there is limited data to help substantiate the predictions at this time, but we hope that we’ll have more results by the time the November issue of The Digest is released in order to compare actual contamination data to this month’s predictions. Join us as we navigate this year’s growing conditions and predict what 2024 corn mycotoxin pressures will be!
