DB Thanks for the info. If melamine passes through the body in a short period of time is it excreted as melamine? If it mixes with other chemicals how much of the mix can the systems of animals and take before there is organ damage?
YL Well sort of. If melamine is excreted through the urine, then it becomes mixed with uric acid, which then may make it more dangerous than it was to begin with. This may be a key element here. If a cow (for sake of example) eats some tainted grass and then urinated it out, onto the ground and then next year eats in the same area, it is now more toxic than the first year because it is mixed with uric acid and now will start to stay in the tissues longer. Then the third year would be worse, of course the original melamine is now at half life but the new compound, melamine/uric acid, it not studied for half life. I can see a vicious circle here, cumulative effects occurring by ingesting the melamine and then passing it through the body, then creating something more toxic, etc, etc. the FDA had said it over and over, and then will backtrack, but they continue to say, melamine does not belong in food, period. Maybe this is one of the unreported side effects, unknown side effects of melamine ingestion. db |

Hey, db, isn't there something about a point at which melamine and cyanuric acid and/or uric acid saturates at some high level of exposure, forms
precipitate in the kidneys, causing stones and nephron tubule damage which is permanent and can no longer be excreted?
3cat That is correct, not sure what the exposure level is though. Melamine by itself does not cause the kidney damage, only when it is mixed with other chemicals, CA, UREA, etc does it start to form the blockage and stones. The body will excrete, in half life, melamine in 3 hours, which means that it probably takes 24 hours before the levels have been reduced substantially. However that does not take into effect the addition of the other chemicals, who knows what those are, and what those half lives are. Don't know if studies have been done on mixing melamine/ca/urea/etc and at what proportions and what those half lives would be. So basically no one really knows how this crap will effect us, pets, babies, etc in the short and long terms. The studies would only be valid for whatever concentrations that were tested on, typically rodents, and then that may or may not be whatever concentrations we are seeing in the melamilk, or melavegetables, melawhatever. db |

YL From what I remember about melamine and it degrading over time, since it is organic it does degrade but usually sunlight is needed for that. I have found nothing about degrading and half life. I will see if I can find something on that. OK, found something. Melamine in the body only lasts up to 3 hours before it is metabolized then the typical half life in a body would be 3 hours, however in the earth it takes years, half life is 3 years, so 3-6 before it would become 1/4. 6-12 for 1/8 etc. So anything within 3 years of planting would most certainly be quite full strength. Oddly enough melamine left in sunlight degrades very quickly?? http://www.inchem.org/documents/sids/sids/108781.pdfdb |

How in the world would melamine get into fresh vegetables?  ? This gets scarier by the minute. Catbird Probably cumulative from the pesticide/herbicide usage in China. Probably becomes embedded in the soil and is drawn into the vegetables when they grow. And again I say, stop importing food from China, period. Until this all gets straightened out, probably never, stop importing food. In another thread, it is now confirmed that they sat on this during the Olympics, they knew about the melamik on Aug 2, but deferred reporting it because of the Olympics. So this is what we are dealing with DB |

"Meanwhile, there could be further problems for Beijing to deal with as more details emerged about a possible cover-up that prevented news getting out until after the Olympics. Communist Party mouthpiece The People's Daily says city authorities in Shijiazhuang, where the company at the centre of the scandal is based, covered up the problem for more than a month from Aug. 2." If this turns out to be proven, It should be a warning signal to any country that still imports from China. Covering up the problem to make the Olympics look good. They would have been better off to come clean immediately, at least we would know that we were dealing with an HONEST govt.  DB |
