Penn State Extension announced on May 19 the launch of a new survey to study mycotoxin contamination in organic corn production systems, targeting producers across several Pennsylvania counties.
The initiative seeks to address concerns about toxic compounds produced by fungi that affect feed quality, animal health, and farm profitability. Gibberella ear rot is especially common in Pennsylvania and can lead to contamination with deoxynivalenol (DON) and zearalenone. The project also aims to assess risks from other mycotoxins as weather patterns change.
While all corn growers face issues with mycotoxin contamination, the announcement highlights that organic producers have unique challenges related to their farming practices. Some modified or “hidden” toxins are not always detected by routine tests but may still impact dairy herd performance even when standard results appear safe. Penn State Extension will offer grain and silage producers the chance to submit samples for a full mycotoxin profile as part of this effort.
The initial phase targets 100 certified organic corn grain and silage producers in Berks, Centre, Chester, Dauphin, Juniata, Lancaster, Lebanon, Mifflin, Northumberland, Somerset, and Union counties. Producers from other areas are also encouraged to participate by contacting the team directly. Participants will be asked to provide samples from either the field or storage—Penn State staff can assist with collection if needed—and complete a brief production survey for each sample.
Each participant will receive a written report detailing findings and recommendations based on test results. The long-term goal is to build a baseline database about mycotoxin impacts in organic grain and silage systems for future research and management guidance.
Penn State Extension delivers science-based education promoting agriculture while ensuring food safety and responsible resource management; it supports community well-being through problem-solving initiatives for individuals and businesses; extends services statewide via local offices and digital tools; collaborates with government agencies as well as industry partners; provides workshops on topics such as farming practices; and focuses educational programming on agriculture, nutrition, pest control solutions, and environmental stewardship according to the official website.
