Description
Micaela Álvarez and co-authors study genes that may shape toxin build-up in a food mold, in a research paper from 2026. The mold Penicillium nordicum grows on cured meats and makes ochratoxin A, a toxin of concern. Salt-rich settings boost toxin build-up. One gene cluster is known, but genes outside it may also play a part.
The team tracked five candidate genes in two mold strains grown at varied salt levels. Three genes tracked toxin build-up in one strain. One gene may help break the toxin down. Two compounds also rose and fell with the toxin. The work refines how salt and genes drive toxin risk in cured foods.
