Feed & Grain

In the past, farmers traditionally have not had a food safety plan in place. Global markets and regulations have dictated a change in that mindset, and we at Charm Sciences partnered with farmers to create test kits and equipment to suit their needs. Charm Sciences provides the feed and grain industry with accurate, easy-to-perform, rapid tests for mycotoxins (e.g., aflatoxin, DON, fumonisin, ochratoxin, T-2/HT-2 toxins, and zearalenone) antibiotics and pesticides.


Grain storage and handling facilities have had to introduce various measures to ensure product safety. The transportation of grain is a key element to that safety, and government regulators expect facilities to know what previously traveled in any container before grain is introduced. If any of the government’s listed prohibited products were hauled, grain employees need proof of cleanliness. With Charm food safety tests, not only can crops can be accurately tested for mycotoxins and antibiotics to be promptly received, but shipping containers and processing facilities can be tested with hygiene tests.

ROSA Lateral Flow Mycotoxin Strips - Charm Sciences

Charm tests can save time (testing in a matter of minutes), money (eliminating brand-destroying recalls), and help keep all customers healthy.

Charm manufactures a variety of ROSA (Rapid One Step Assay) tests to detect mycotoxins (aflatoxin, DON/vomitoxin, fumonisin, ochratoxin, T2/HT2, and zearalenone) in feed and grain. Utilizing innovative ROSA technology, Charm lateral flow mycotoxin tests are easy to use and provide rapid, quantitative results. All ROSA mycotoxin tests follow a similar assay format and can be read on the same equipment.

Test results from ROSA strips may be read and officially recorded using the Charm EZ-M system.

Meets European Union regulations

Sample extractions for ROSA mycotoxin tests can be performed using different solvents, including water, ethanol, and methanol. Water Extraction Technology (WET) was developed by Charm to eliminate the need for organic solvents previously required to extract some mycotoxins.
