Data on the presence or absence of genes encoding essential proteins for ochratoxin and fumonisin biosynthesis in Aspergillus niger and Aspergillus welwitschiae

Cross-Sectional Study

In Vitro

2016 Jun

The study found that 17% of the mold strains from Brazilian food samples had all three genes linked to producing two harmful toxins, which matches the claim exactly.

Similar Assertions

About a third of certain mold strains found in Brazilian food don’t have the genes needed to make two harmful toxins, which means they probably don’t produce them.

Some mold found in Brazilian food has the genes to make a harmful toxin called ochratoxin — about 1 in 30 of these molds could make it, but not another toxin, suggesting a small risky group we should watch.

A lot of mold found in Brazilian food has the gene needed to make a toxin called fumonisin — about 7 out of 10 samples — and sometimes it also has genes for another toxin, which means these molds could potentially produce harmful substances.

More than half of the black mold strains found in Brazilian food have a gene that could let them make a harmful toxin, but they're missing other genes—so they might only be able to make one type of that toxin.
