The research on this appears to be very sketchy. Here is what I have found so far.
When the Chinese added plastics to their protein foods such as milk so that they could skimp on the food and make more money, they did not use pure melamine. They used a mixture of chemicals that was part melamine and part other plastics and chemicals. Melamine causes kidney disease including stones and bladder cancer, so it is what caused these corporate criminals to get caught. However, there are a bunch of other potentially toxic chemicals that can also cause pets and humans medical problems, some of which would not be immediately obvious.
My suspicions were raised, because my husband, who used to drink protein supplements daily and who had recurrent kidney stones at that time also had a strange eye condition. He developed vision change, went to the ophthalmologist, was told he had acute inflammation of both retinas. A few weeks later the inflammation was gone but he had developed micro aneurysms. Since he is diabetic, he had been receiving routine eye exams and had never had MAs before. His sugars had been well controlled. This was years ago, and he has never shown any sign of protein in his urine or diabetic kidney disease which usual develops at the same time that eye problems develop, which made me wonder if the eye problem was not the usual diabetic eye disease
Anyway, this is what I have learned about the junk they have been putting into Chinese milk.
This site has a WHO document:
http://hygimia69.blogspot.com/2008/09/melamine-and-cyanuric-acid-toxicity.htmlWhich lists the adulterants in pet food:
Analysis of the contaminated ingredient (gluten) responsible for this outbreak revealed the following triazine compounds: melamine 8.4%, cyanuric acid 5.3%, ammelide 2.3%, ammeline 1.7%, ureidomelamine and methylmelamine both <1% (Dobson et al 2008).
Now, I don't
know that the factory owners in China added the same stuff to the human food that they added to the pet food, but the type of people who would add plastic to food in order to make to seem healthy are not likely to say to themselves "We need to use only the highest grade, purest melamine to adulterate our baby formula." No, they will use the same cheap industrial waste to cut the milk that they used to cut the pet food. Whatever the plastic factory is selling on the side, that is what they will buy.
http://en.wikipedia.org/wiki/AmmelineAmmeline is the first step in melamine hydrolysis.

ammeline caused blindness in chicks within 2-7 days when it was added to their meal to increase protein content. It has a special affinity for the retina. It caused edema, cellular degeneration and retinal detachment.
In
Opthamalogic Toxicology http://books.google.com/books?id=Xo8ZKwCm-2sC&pg=PA67&lpg=PA67&dq=ammeline+eye+toxicity&source=web&ots=hq8BO4t8oW&sig=C8-6eHWVzI-sWAJ5RzQU1U4IL6A&hl=en&sa=X&oi=book_result&resnum=6&ct=resultAmmeline is described as causing damage to the retinal pigment epithelium (
http://en.wikipedia.org/wiki/Retinal_pigment_epithelium ) which in turn causes degeneration or damage to photoreceptors (light receptors) of the eye.
Unfortunately, getting our government to study toxicity of some of these breakdown products of melamine may be difficult since U.S. industry has good reason to want to reassure the public that there is nothing to see here, move along. Here is a report from the manufacturing industry which denies any potential for human toxicity from ammelide or ammeline from 2001 called
Urea-Scr Byproducts Probably No Health Threat .
http://findarticles.com/p/articles/mi_m0CYH/is_/ai_79409490Maybe they are correct. However, when someone puts the stuff in your food, that is a whole different matter and it needs to be studied. Is Ammeline/Ammelide causing damage to the eyes of millions of people in China and around the world which no one suspects yet, because babies can not describe their vision and no one has looked at their eyes? Are these chemicals a particular problem for diabetics or the elderly or for other people who are already at risk for retinal disease?
I think that someone needs to start studying the effect of Chinese milk doping on eyes as well as kidneys.
If anyone at DU knows of any research into the matter please post a link.
