What does vomitoxin look like in wheat?
Bleached spikelets are sterile or contain kernels that are shriveled and/or appear chalky white or pink (Figure 3), referred to as Fusarium-damaged kernels, scabby kernels, or tombstones. Scabby grain usually contains the mycotoxin deoxynivalenol or DON, also known as vomitoxin.

Several methods including thin-layer chromatography (TLC), high-performance liquid chromatography (HPLC), mass spectroscopy, enzyme-linked immune-sorbent assay (ELISA), and electrochemical immunosensor, among others, have been described for detecting and quantifying aflatoxins in foods.
Is there a Don advisory level for wheat intended for milling?
FDA is not stating an advisory level for wheat intended for milling because normal manufacturing practices and additional technology available to millers can substantially reduce DON levels in the finished wheat product from those found in the original raw wheat.
