The risk of aflatoxins, mycotoxins are highly carcinogenic (liver) produced by fungi of the genus Fusarium present mainly on the ears of corn in the open field, on the ears of grain and grain silos until well chilled, it is getting worse. And what is more serious for the health conscious, even more about the plants cultivated by the method "organic." Many believe that these toxins are present only on seeds and grains imported from the Far East, but it is not. Unfortunately colonize even our farmland. Therefore, we report the article-appeal on 9 November 2004, three super-experts, Giorgio Poli (Dean of the Faculty of Veterinary Medicine, University of Milan), Francesco Sala (Professor of Botany, University of Milan), Luigi Bonizzi (Professor of Veterinary Microbiology, University of Padova), published in the Corriere della Sera . While realizing that the article tends to the introduction of GMOs. Right now, after years of our position in favor of theoretically based on the liberal principle of freedom of research, we were now against, at least the opportunity for economic, ecological, agronomic, social and even biological diversity (on the field and at the table ). Now toxicological concerns appear to return the balance to the center. .
We note, however, that does not appear that in Italy the rate of liver cancer (aflatoxin B1 target organ) is worrying as in the Far East. A sign that the abundance of vegetables and fruits in our diet, which in the East dreams, has protective effects on aflatoxins. It's worth a serious risk, of course, but luckily still limited and under control, upsetting the entire agriculture with a choice from which you can never go back, destroying hundreds of old varieties that still survive (the GM crops are very pervasive) and forcing the poor and marginal farmers to buy new seed for each crop by the oligopolists of proprietary companies? "Our" Adam Smith did not say that freedom, the welfare and happiness of all citizens are in incomes, even in monopoly rents, one or two agricultural genetics company. Okay, we'll be cynical liberals, but possible that 60 million consumers are worth less than 10 board members? In short, the shadow of speculation of a monopoly is so strong that the "unspoken", the silence on the many negative aspects, and introduces disturbing purchases contours in the matter - it - obscure and irrational elements. The notorious "Bugiardini" attached to the drugs are examples of transparency and scientific objectivity in comparison with the reticence and the one-sided propaganda of the proponents of GMOs at all costs.

"Emergency Aflatoxins: thousands of tons of milk seized in Italy and destroyed. A subject that for some weeks in autumn 2003, he held the press and concerned professionals in the food chain and now has returned to prominence at the Alemanno bill on GMOs. But what is it? We really have to worry about?
last year were found in milk toxic and carcinogenic substances (mycotoxins) produced by fungi that colonize food. The most dangerous, the Aflatoxins are produced by the fungus Aspergillus flavus and accumulate mainly in corn and peanuts. Aflatoxin B1 is the most hepatocarcinogenic powerful ever known, so that the IARC (International Agency for Research on Cancer) places it in the highest risk category.
Under favorable conditions are mycotoxins produced by fungi in infested plants in the open or under any of the stages of production and processing of food legislation. In addition to causing yield losses and reduction of quality, fungi contaminate the seeds with mycotoxins. The special climatic conditions of 2003, but in 1999, had created favorable conditions for fungal infestation of corn used in feed for cattle, and then the discovery of mycotoxins in milk.
E 'has been shown that the accumulation of toxins fungal infections in plants and grains of corn is directly correlated with the level of infestation with insects, especially the European corn borer, the declared enemy of the corn. The larvae of this insect tunnels dug into the frame and weaken the plant by blocking its growth. But often, the insect carries on his body even fungal spores. These are a favorable environment for development in plants weakened by borer itself, is an event very similar to what happens in individuals debilitated by organic diseases that are more susceptible to infection. The result is that the growth of the plant freezes and the stems and ears of corn are covered with a clear network of fungal hyphae, producing carcinogenic toxins. These, eat animals, accumulate in milk and meat and are a real danger and scientifically demonstrated that probably we have always lived. Today, science has explained how these substances appear in foods, which have effects on our body and also gives us the methods to recognize and avoid them.
The first way to eliminate carcinogenic toxins from corn is represented by checks: Zooprofilattici Institutes carry out the analysis of milk samples and ensure that contaminated milk is destroyed. Unfortunately, not all of the milk consumed in our country is subjected to controls, and big questions about the milk powder.
In conventional maize infection is controlled, even if only partially, with insecticides. But the scientific data say that this does not completely eliminate the risk of aflatoxins, a recent study at the Catholic University of Piacenza, for example, has revealed worrying levels of aflatoxins in more than 18% of maize samples analyzed. The situation becomes even more critical in crops "organic", which is prohibited the use of synthetic insecticides. These are replaced with a bacterium that produces an insecticidal protein, which is not as effective in controlling corn borer. The data analysis reveals these crops in the record of the presence of carcinogenic mycotoxins. The same
vale anche per il latte: recenti ricerche pubblicate dall'Istituto Zooprofilattico di Brescia hanno evidenziato che molti dei campioni di latte di stalla analizzati presentano alte contaminazioni da aflatossine, e questo è vero soprattutto per il "latte biologico". E ciò è ancor più preoccupante se si considera che il problema aflatossine non è limitato a polenta e latte, ma è allargato a tutte quelle colture che non siano sufficientemente protette dalle infezioni fungine, come, ad esempio, la vite e l'olivo.
Uno studio pubblicato dall'International Service for the Acquisition of Agri-Biotech Applications (Isaaa) indica la soluzione al problema aflatossine nell'adozione del mais Bt: si tratta di un mais Ogm che, in seguito introduction of an exogenous gene, naturally resistant to infection by an insect pest. It is equipped with an insecticide that prevents the survival of the domestic corn borer in the stem, and then the fungi associated with it. The plant grows healthy, does not need pesticides and is, to analysis, to contain, on average, 5-10 times less toxins than conventional maize. Unfortunately, this corn is grown by more than 10 years in the fields of maize in many countries of the world, falls under the category of GM plants, and therefore by law is excluded from our kitchens and our feed, while, paradoxically, the biological is made mandatory in kindergartens and schools in many regions.
Scientific research, as we have seen, shows us that it is not always true that organic products are healthier, environmentally friendly and free of chemical residues. The scientific data are making clear the risks and benefits of organic, conventional and biotech agriculture. Science alone, above the economic interests of a party, we can help develop more healthy diet, so it is important to take this into account. "
