too, if not a security baseline,http://www.infocrystal.com/alink/apeboard_plus.cgi?command=read_message&msgnum=970/, vaguely talk about "security" - or,christian louboutin pas cher, as many people expect "absolute security" can not be discussed. "Absolute security" can not be proved logically. We can not prove that eating on thousands of years of food is "absolutely safe". Such as peanuts, wheat, beans, milk,nike pas cher, cassava and other foods,http://www.gruot.net:87/forum.php?mod=viewthread&tid=10456153, we have a long history of eating,louboutin chaussures, until modern times, people know they can make some people allergy or poisoning, serious enough to cause death. In general,http://www.postyourblowjob.com, we can accept those with a long history of food consumption is "safe". Therefore,louboutin paris, in assessing the safety of GM crops, we are the genetically modified crops and the corresponding no alteration compared to the former may exist if "security risk" than the latter is high,chaussure tn pas cher, both considered "risk equivalent . " Since we believe that the latter is "safe".
the expression product of the Bt gene in bacteria -Bt insect protein, was used as a "green pesticides", it can be used in organic cultivation. The Bt gene is transferred into the insect-resistant crops in time, Bt proteins have been decades of "safe use" of history. Secondly,barbour pas cher, we must determine the safety of gene expression products. For example, Bt gene expression product is Bt protein,nike tn 2014, we need to make sure it will be digested by the stomach, not having an active, but not like eating after being worm is activated to produce toxicity. At the same time, we must make sure it does not cause allergies. Such as Golden Rice, turn into the gene expression product out of the carotene. Security audits need to confirm this with the express carotene carotene people usually eat the same, and in the normal rice consumption does not exceed "safe intake." After the third, but also consider the transferred gene, it is not it will affect the crop gene expression, resulting in harmful ingredients. Modern molecular biology techniques have been able to more clearly identify the influence after gene transfer to other genes. If there is no impact, then the chemical composition of GM crops and traditional crops corresponding to no substantial difference. If it does.
then we should accept the former is safe. This is GM food safety audit of a "risk assessment" - it's not going to prove GMO "absolute security", but to assess it and the corresponding non-GM varieties compared to no increase in security risks. GMO safety review "Case Auditing" and "risk assessment" is GMO safety review in two basic principles. When a GM varieties appear when the "risk assessment" is how it? If we go to a strange place, he saw an unfamiliar food, they tend to issue "this thing eat it,escarpins louboutin," the doubts. Man as an animal, this should be a self-preservation instinct,giuseppe zanotti sneakers,http://www.xmarks.com/s/site/www.tadayumi.sakura.ne.jp/apeboard_plus.cgi/os/, understandable. At this time, if there are people who trust us in detail about the kind of food raw materials and production methods, and the possibility of "problem" of these raw materials and production methods are what we can predict, can be controlled,tn requin, so many people will probably be able to accept a "new food" was. Risk assessment of genetically modified foods,louboutin, this is equivalent to the risk assessment of each feedstock and each procedure may bring. Codex Alimentarius Commission a detailed assessment guidelines, the following describes only the most critical aspects: First,nike air max, the source of the transferred gene. Any transgene has a clear purpose, and this object is achieved by the transfer of genes into implementation. Some people worry about "if the food was turned into a pig gene,air max pas cher pour homme,http://www.infocrystal.com/alink/apeboard_plus.cgi/, Muslim compatriots to eat, how to do," purely unfounded. Are there genes help grow food, even turn will clearly be explained, will not lead to "eating" Not to mention the pork. Like hiring an employee will investigate their background,nike air max baratas, as in the prior transfer a gene should review its pedigree background. By gene transfer eating crops, must be "innocent life experience" - provided the gene species,barbour pas cher, generally we need to have "a long history of safe use" non-toxic, does not cause allergies,http://www.xmarks.com/s/site/www.tadayumi.sakura.ne.jp/apeboard_plus.cgi/uopingcha/, and so on. For example,tn, the most common insect-resistant gene Bt, derived from a bacterium, is widely found in nature. From the beginning of the 1920s.
you need to further evaluate these effects are good or bad. If it is good, that be a pleasant surprise; if it is bad, then this would sink like a stone of genetically modified crops. In fact, the other "traditional" breeding methods, such as miscellaneous home breeding, mutation breeding, are also likely to change in the third. Genetically modified species of environmental safety In addition to food safety,http://www.postyourasian.com,chaussures louboutin, environmental safety of GM crops is the one aspect of the high-profile. For example,tn, fear of anti-herbicide gene flow to the natural world,http://www.postyourasian.com, "superweeds" resistant Transgenic fear causes a "super bug.
