Brazil: a model country that has launched a heavy blow on the mycotoxin problem and effectively solved the mycotoxin problem.

At the end of this post, edited by Cui Ruowei at 17:16 on 2009-11-27, Brazil, a model country for effectively solving the problem of mycotoxin, has set another example in terms of Brazil's leading position in the world. Twenty-five years ago they decided to stop relying on oil and start producing ethanol from sugar cane, which is almost five times more efficient than extracting it from corn and does not affect global feed or food prices. This time its lead lies in the issue of mycotoxins. Brazil is the world's largest grain producer and one of the exporters of poultry and pork. Grain growers have been lucky for many years because their only mycotoxin problem is aflatoxin. In the past four years, this situation has changed dramatically. Fusarium moniliforme toxin, F2 toxin and vomiting toxin began to be detected in corn, wheat and soybean, and the content is very high, affecting animal production. Mycotoxin adsorbents that provide solutions to all problems have emerged, and they are more aimed at selling products than really solving problems. Faced with the mycotoxin problem and so many products, the Brazilian government decided to take tough measures to provide a real solution to this major problem. Unlike the fact that carcinogens are not allowed in feed in the United States, or that EU regulations stipulate that the dose of mycotoxin in feed is very small, Brazilians solve the problem in a very effective and feasible way. They are aware of their mycotoxin problems, so they have set up a committee of scientists and experts in the field of mycotoxins to create and develop methods and regulations for approving mycotoxin additives (adsorbents, detoxification agents). The Committee concluded that the implementation of a programme for the approval of mycotoxin adsorbents would go through three stages of trials in Brazilian universities considered to be a leader in the field of mycotoxins. Federal University and LAMIC Laboratories have been appointed to carry out this programme. Founded 15 years ago, LAMIC Lab is one of the top five independent mycotoxin laboratories in the world. The laboratory has nine sets of HPLC equipment and a set of MS/MS spectrophotometers that specialize in independent analysis of mycotoxins. At the same time, they also have their own pig and poultry research centers to do experiments in animals. LAMIC is an economically self-sufficient laboratory whose main function is to provide services to farmers rather than manufacturers of mycotoxin adsorbents. The approval step of the in vitro experiment began with the in vitro experiment, using different levels of mycotoxin adsorbents at different PH values. Mycotoxin levels varied from 1000ppb to 2500ppb depending on the mycotoxins to be tested. If the product performance is good, the efficiency is more than 80% before we can move on to the next stage. The second stage of the in vivo experiment is the in vivo experiment, which requires the same mycotoxin to be done at the level of 1000ppb to 2500ppb at the same time, and tested on a special animal. The key part of the target organ in this experiment is that the anti-mycotoxin additive must be statistically shown to have a very effective effect on the target organ. For example, aflatoxin is the liver, Fusarium toxin is the lung, F2 toxin is the reproductive organ, T2 toxin is the oral organ, and so on. Therefore, this approved product year is not only based on improving the immune system affected by mycotoxin or restoring an enzyme, but also to prove that the product has a direct and effective effect on the target organ. In addition, in aflatoxin and Fusarium oxysporum toxin tests, mycotoxin adsorbents must be statistically shown to have a significant effect on body weight and feed intake, which can undoubtedly prove that the product is effective. The third phase involves testing the in vitro and in vivo efficacy of mycotoxin adsorbents every 6 months to ensure that manufacturers sell the same products as originally approved. Few products were approved this project was carried out a year ago, and only a few products were approved, the vast majority of the products passed are clay products: only 30% can be used in Brazil through in vivo and in vitro tests, and only 30 products have passed. Of these, 29 are clay products-the world's mainstream products are clay products. Since the implementation of the new regulations in 2007, non-yeast adsorbent products have been tested in Brazil. The products that passed the test (30): poultry: Huangqu, 18; beads, 2. Pigs: Huangqu, 3; beads, 1; F2, 6. Mildew can be removed through the situation: poultry: yellow koji, beads (mildew can be removed AD) pigs: yellow koji, beads, F2 (mildew can be removed AZ) on pigs, there is only 1 product that is effective against the three most important mycotoxins at the same time, that is, the moldy detachable AZ produced by American Special Nutrition Company. The myth was shattered by the adoption of this approval program, together with the confirmation of other recent conclusions presented at the American Conference on Poultry Science and Animal Engraving Science and the 2006 World Mycotoxin Forum. (clay products have been attacked) 1) Clay acts only on aflatoxins; 2) all clays are equal. It has been proved by LAMIC that some clays are very effective against several mycotoxins including F2 toxin and Fusarium oxysporum toxin (e.g. AZ). Brazilian manufacturers should be proud of LAMIC's professional work and should also thank the government for its actions to prevent the sale of mycotoxin adsorbents aimed at marketing rather than rigorous scientific evaluation. For other parts of the world, their governments have not yet adopted a scientific method to approve manufacturers of mycotoxin adsorbents, and if the products provided have been tested and approved by LAMIC, using such products can protect themselves in the market.
