Paying to find non-GE wild corn?

The fungus is a cereal pathogen and consequently zearalenone is found in wheat, barley and corn. I can't see why zearalenone could not be produced by Fusarium in red clover hay, but you are right it is most commonly found in grain, notably corn. It is sometimes fed to animals to increase their growth. That's not quite right, I think, but the anabolic substance, or 'beef hormone' you are probably thinking of, common name "Zeranol", might exist in metabolic relationship with zearalenone in animals fed zearalenone-contaminated feed stuffs. Another name for the beef hormone Zeranol is alpha-zearalanol, it differs chemically from zearalenone by the absence of a double bond and the reduction of a ketone group to hydroxyl in the large lactonic ring of the general bicyclic structure of the 'zeranol-group' of compounds. Pharmacologically zeranol differs from zearalenone by having higher estrogenic activity, indeed in some tests it has been found to be as potent as high potency synthetics like (infamous) diethylstilbestrol and ethinyl estradiol. The use of zeranol is banned in production of meat in the EU, because the EU as a matter of principle does not license the use of meat production aids which pose carcinogenic/mutagenic risks to consumers. In e.g. renegade USA such risks to consumers are accepted, and zeranol is widely used in beef production there. The estrogenic compounds in clover include genistein, same as one in soy. Note clover is Genista. Dave Have you ever had cows on red clover to any extent? Then have you noticed any affect on them? Or the estrogenic mycotoxin zearallenone? Don't some farmers use it as a steroid to increase growth of animals? I think I posted how it reduces fertility. My question is whether the extra estrogenic nature of GM-produced animal feed causes any changes in the developing embryo, or fetus, in a similar fashion to what other estrogenic foods do. My first question would be if there is an extra estrogenic nature of GM-produced animal feed. But, it would seem prudent to be open to the possibility that some genetic engineering events in e.g. soy might unintendedly result in elevated levels of phytoestrogens, or phytoestrogen profile changes. |
