I thought for those who have recently encountered the topic of Melamine sprouting up, that this was a decent article to read: http://www.sundaytimes.lk/081102/Plus/sundaytimesplus_14.htmlMelamine: Do you know what it is? By M.C. Mohamed Zakeel.. (The writer is lecturer, Rajarata University of Sri Lanka)
Melamine is an organic base and a trimer of cyanamide, with a 1,3,5- triazine skeleton. Like cyanamide, it contains 66% nitrogen by mass and if mixed with resins, has fire re tardant properties due to its release of nitrogen gas when burned or charred, and has several other industrial uses. Melamine is also a metabolite of cyromazine which is a pesticide.
It is formed in the body of mammals that have ingested cyromazine. It has been reported that cyromazine can also be converted to melamine in plants.
Melamine combines with cyanuric acid in a ratio of 1:1 to form melamine cyanurate. It is also known as melamine-cyanuric acid adduct or melamine-cyanuric acid complex. Melamine cyanurate forms spoke-like crystals from aqueous solutions and has been implicated as a causative agent for toxicity seen in the Chinese protein export contaminations and the 2007 pet food recall. Melamine cyanurate is commonly used as a fire re tardant.
Melamine is a German word coined by combining the names of two chemical products: Melam (a distillation derivative of ammonium thiocyanate) and Amin.
(snip)
On October 3, 2008, the U.S.Food and Drug Administration said that up to 2.5 parts per million of melamine was safe for adults, but declined to set a standard for children. However, anything less than zero tolerance would not protect consumers. |

Now it's that plastic stuff growing in your kidneys that the US government is doing virtually nothing to protect US consumers from eating I'm afraid. |

I am appalled at how melamine has been appearing in all sorts of food --- who knows how long this has been going on--- I have a nasty suspicion that I have plastic in my kidneys now  |

Anyone know of any type of blood test or other test to detect in the human body in the US? Since we send our pet food to labs there should be something we can do to find out and next would be - how would the body be able to rid itself of any build-up?

I would think a protein( nitrogen would give a heads up... ie if it is high |

When they were feeding it to the hogs, they were testing the urine. We prob pass a certain amount of it, so a trace test may be possible with urine. Ridding of the buildup I'm not sure about. Seems like I remember reading something about raising the acidic level of the urine rather rapidly. Basically you need to dissolve the crystals enough to detach and pass them. Healing the damage they cause, who knows. I would turn to whole foods and natural supportive supplements to let the body heal thyself, but that's just me  When are the melamine dipsticks coming out? |

straybaby yes whole foods and supplements are definetly in use here but if anyone had any residue. I know charcoal capsules soak up a lot of toxins but do not know if they would work on plastic. Will have to check out more on that.

Here is some info about the ph and the melamine cyanurate crystals...somewhat over my head... http://pubs.acs.org/cen/science/86/8619sci3.htmlAs Puschner suggested, the behavior of melamine and cyanuric acid depends on pH. Tolleson determined that different pH values in different zones in the body influence the solubility of melamine and cyanuric acid, "just as you would predict from the acid-base dissociation constants for those compounds." The compounds are most soluble in the acidic conditions of the stomach and least soluble near pH 5, which is found in parts of the kidney, he says.
Under neutral conditions, the compounds form a stable and insoluble hydrogen-bonded network; the network is destabilized at pH extremes. Accordingly, melamine cyanurate crystals could be expected to form in blood, which has a neutral pH. But they don't. "The hypothesis is that serum proteins might sequester one or both of the triazines and allow them to remain in circulation until they can be deposited in the kidney, where they precipitate," Tolleson says. He is now searching for triazine-binding proteins in the blood and urine and is studying proteins found together with melamine cyanurate in crystals.much more at link...  |

"When are the melamine dipsticks coming out?" About the same time that the dipsticks in DC finally take a stand to protect the citizens they are supposed to represent.   |

JanC good one. Add to that - if they are hoping for the dilution/disappear factor (as in eating it and its gone, no more proof) melamine builds up accumulation otherwise how would stones ever start forming without this added toxin in the body of yourself or your pet? There will be no getting around this - it doesn't dilute and disappear like one would think. Pets are still struggling on a daily basis from the melafeed in the pet food so dilution would not come into play here at all. How many humans have stones and not a clue how they got them too.

You can pee on a stick to find out if you're pregnant, if you're ovulating, if you have a UTI.... why not to find out if you have been poisoned by melamine! |

In talking over the phone to a UC Davis vet about a frozen urine sample in June 2007, I was told -- and I can't
vouch for the accuracy -- that if my pets' exposure to melamine occurred in Dec. 2006 and/or January 2007 [which
I believe was the time period based on the pet food recalls], then the food sources were changed post-diagnosis
of renal problems in January 2007, and the urine sample was not taken until early May, after that time lapse, there wouldn't
be any melamine crystals in the urine any more. I absolutely can't vouch for the accuracy of that statement, but that is
to the best of my belief exactly what I was told. Not likely to forget it in view of the results at my house. Based on
that, you'd have to be melamine dipsticking an awful lot I believe to get accurate results on people pee.
