Grass-fed, grass-finished, regeneratively raised meat is preferred to avoid mycotoxins like aflatoxin and ochratoxin from moldy grains.

“This is one of the reasons that I'm such a fan of grass-fed, grass-finished, regeneratively made meat is because if you feed a cow grains, do you think that they have given any attention to the quality of those grains? They're very likely to be moldy grains, which can contain aflatoxin, they can contain all sorts of other problems, aspergillum, uh, all sorts of other molds, ochratoxin fumonisins etc.”
