Medium relevanceAccumulation of HT-2 toxin from contaminated mushroom compost by edible Agaricus bisporus.
Pleurotus ostreatus
Key points
- Wheat straw is commonly used as a cellulose source in mushroom compost and could be a secondary source of mycotoxin contamination in the food chain
- We cultivated edible Agaricus bisporus and Pleurotus ostreatus on T-2/HT-2 artificially-contaminated mushroom compost and developed and in-house validated an UHPLC-MS/MS method for determination of T-2, HT-2, T2-triol and T2-tetraol in mushroom compost and mushroom basidiocarp
- A rapid phase I metabolization of T-2 and HT-2 in mushroom compost was observed
- In Agaricus bisporus, basidiocarps 8-15 µg kg -1 accumulation of HT-2 calculated on wet weight was measured
- No detectable mycotoxins were found in Pleurotus ostreatus basidiocarp

Citation abstract
Wheat straw is commonly used as a cellulose source in mushroom compost and could be a secondary source of mycotoxin contamination in the food chain. We cultivated edible Agaricus bisporus and Pleurotus ostreatus on T-2/HT-2 artificially-contaminated mushroom compost and developed and in-house validated an UHPLC-MS/MS method for determination of T-2, HT-2, T2-triol and T2-tetraol in mushroom compost and mushroom basidiocarp. A rapid phase I metabolization of T-2 and HT-2 in mushroom compost was observed. In Agaricus bisporus, basidiocarps 8-15 µg kg -1 accumulation of HT-2 calculated on wet weight was measured. No detectable mycotoxins were found in Pleurotus ostreatus basidiocarp.
