Aflatoxins in Peanuts
Aflatoxin in peanuts is a major concern but you can easily avoid them by visually checking the nuts. The moldy, discolored parts on nuts may be a sign of fungus colonization on the fruits. Look for these signs on peanuts and avoid buying those infected to reduce the risk of exposure to aflatoxins.

What does aflatoxin look like?
Aflatoxin is a naturally occurring toxin produced by the fungus Aspergillus flavus. The fungus can be recognized by a gray-green or yellow-green mold growing on corn kernels in the field or in storage (Figure 1).
Which nuts have the most aflatoxin?
Among the nut products, pistachios are extremely contaminated with AF (8). In an Iranian study, the mean level of AF in pistachios was recorded as 7.3 ± 53.2 ng/g which was lower than the AF maximum tolerated level (MTL) of Iran (8).
Does soaking nuts remove mold?
Yes, that’s right. Most nuts have mold on them. You may not be able to taste or see it, but they’re kept in storage bins for weeks or months and accumulate mold, which produces toxins called mycotoxins. Soaking nuts helps reduce and eliminate mold from the nuts.
