An original study published online in September 2025 in Food Chemistry tested for 22 mycotoxins in 248 soft and durum wheat samples collected before and after harvest and during storage, in two Moroccan climatic areas between 2020 and 2022.
UHPLC-MS/MS analysis detected contamination in 53% of samples from the littoral area, compared with 31.5% from the continental area. Several mycotoxins could occur in the same sample. However, only four of the 248 samples, or 1.6%, exceeded Moroccan and European regulatory maximum limits.
This finding calls for vigilance without alarmism: detecting a mycotoxin does not automatically mean that a product poses an immediate danger. The study covered two areas and wheat grains; it assessed neither individual dietary exposure nor clinical effects and does not describe the entire Moroccan market.
The practical priority is therefore risk-based monitoring from harvest to storage, with moisture control, appropriate storage conditions and regular analytical checks.
