Cross-sectional surveillance reveals widespread co-occurrence of Alternaria toxins in harvested wheat, highlighting the need for regulatory limits on mycotoxin contamination.

Key Points

To assess the occurrence, distribution, and co-contamination profiles of four Alternaria mycotoxins in freshly harvested wheat kernels.
Collected and analyzed 370 freshly harvested wheat kernel samples from Anhui province, China, in 2015 (N=370).
Quantified concentrations of tenuazonic acid (TeA), tentoxin (TEN), alternariol (AOH), and alternariol monomethyl ether (AME) using high performance liquid chromatography-tandem mass spectrometry (HPLC-MS/MS).
TeA was the predominant toxin detected, followed by TEN, AOH, and AME, with 95% (352/370) of wheat samples testing positive for multiple Alternaria toxins.
Toxin levels exhibited geographical variation, with samples from Fuyang district demonstrating significantly higher TEN concentrations than other regions (p < 0.05).
Significant positive correlations occurred between TeA and TEN, AOH and AME, TeA and AOH, and total dibenzopyrone derivatives (AOH + AME) and TeA.
