New corn flour standard helps labs catch toxic mold contamination
Food Safety
If you grow or store your own corn, the mold that produces aflatoxins thrives in warm, damp conditions exactly like a poorly ventilated harvest bin, and this reference material is what keeps testing labs honest about catching it.
Aflatoxins are nasty toxins made by mold that can grow on corn, and they're dangerous even in tiny amounts. To catch them, labs need a reliable 'answer key,' a batch of corn flour with precisely known toxin levels, so they can check their equipment is measuring correctly. This paper describes how researchers built and verified that answer key.
Key Findings
1
Researchers developed a corn flour certified reference material (CRM) with established aflatoxin concentrations for lab calibration.
2
The material allows testing labs to validate accuracy of their aflatoxin detection methods against a known standard.
3
Certified reference materials like this support consistent food safety enforcement across different labs and countries.

Technical Summary
Scientists created a standardized corn flour sample with known aflatoxin levels so food safety labs worldwide can check whether their toxin-detection equipment is actually accurate, helping ensure corn products on shelves are properly screened for this dangerous mold toxin.
Maize, also known as corn in North American English, is a tall stout grass that produces cereal grain. The leafy stalk of the plant gives rise to male inflorescences or tassels which produce pollen, and female inflorescences called ears. The ears yield grain, known as kernels or seeds. In modern ...
