Testing for Toxins?
With the roller coaster weather seen this year the presence of mycotoxins on corn, grains and forages is a risk. Two of the most common mycotoxin-producing fungi, Fusarium and Aspergillus, in particular are already being seen in different areas of the U.S.
Cool, wet weather like what was seen this spring favors the growth of Fusarium sp. that can produce deoxynivalenol (vomitoxin), zearalenone and T-2 toxins. Affected crops include corn and other small grains and forages. Other fungal pathogens such as Diplodia ear rot are also being seen, but this fungus does not produce mycotoxins.
Late summer brought more hot and dry weather, including severe drought conditions in the south. This hot, dry weather also favors Fusarium sp. that can produce the group of mycotoxins fumonisins as well as Aspergillus, which produces aflatoxins, a group of particularly potent carcinogens.
Increasingly export destinations may require for the presence of specific toxins to be tested. In particular this fall, China has increased requirements for ochratoxin A and zearalenone testing prior to shipment to China. Ochratoxin is produced by Aspergillus and often appears with aflatoxin. Zearalenone is produced by Fusarium and is often found with Vomitoxin.
SGS provides testing for all of the mycotoxins discussed above utilizing both USDA-GIPSA validated ELISA (Enzyme Linked Immunosorbant Assay) testing methods and LC MSMS (Liquid Chromatography with tandem Mass Spectrophotometry), depending on the level of detection and quantification needed.
