Multiple mycotoxins detected in
corn, soya and sorghum samples from Bolivia, Columbia, Argentina and Chile

⇰ This mycotoxins survey was conducted between January and June 2021.

In Colombia and Bolivia this analysis was performed with REVEL Q+MAX kits and in Argentina and Chile REVEL Q+ kits (Neogen) were used for analysis of mycotoxins from these samples.

The samples were analyzed for:

• Total aflatoxins
• Total fumonisins
• Deoxynivalenol (DON)
• Zearalenone (ZEN)
• T-2 toxin

The results of this survey are presented as below.

The average of each mycotoxin detected (ppb) in the corn samples from Argentina is shown in Table 1.

• ⇰ Fumonisins and DON were the predominant mycotoxins detected with a high average contamination level found.
• ⇰ Aflatoxins, ZEN, and T-2 were found to be present at lower average contamination levels.
• ⇰ Aflatoxins, fumonisins, DON, ZEN, and T-2 toxin were detected in all (100%) corn samples.

All the corn samples (100%) from Argentina had more than 1 mycotoxin per sample. Therefore, corn samples from Argentina had co-occurrence of more than one mycotoxin.
