Mycotoxin contamination in edible and medicinal plants seeds is a potential toxicological concern for consumers. A novel, green and efficient defatting and de-pigment clean-up pretreatment was first developed for the simultaneous determination of 31mycotoxins via freeze-out combined with solid-phase extraction. Combination of freeze-out and solid-phase extraction can achieve a double clean-up effect: defatting and depigmenting. The combination of the two can achieve a double clean-up effect. Excellent performance characteristics of method validation, inter-and intra-day precision (RSD <10%), and recovery (79.5-125.1%) were obtained, fulfilling the current legislation. Alarmingly, of the 117 batches of samples, more than 30% contained more than one kind of mycotoxin, 7.69% of which were detected at levels exceeding the limits defined in the European Pharmacopoeia, and four of which were detected at levels over five times higher than the maximum residue level. Furthermore, two risk assessment methods identified aflatoxins and Zearalenone as the most risk-inducing mycotoxins in...
