Compounds found in poisoned pets: Melamine/Urea, cyanuric acid, amilorine and amiloride:

I was looking for products that contain two or more of these compounds and found this:.   

Feed Grade Biuret is a non-protein nitrogen “protein booster” for use in cattle feed. 

Feed Grade Biuret is produced by the partial hydrolysis of urea and consists of a mixture of:
Biuret
Urea
Cyanuric acid
Triuret
and other homologs. 

Like Wheat Gluten and Rice Protein Concentrate, Feed Grade Biuret is a white powder.

Feed Grade Biuret is implicated in this April, 2005 http://www.hetai-industry.com/news.html Chinese Gluten Importer website as being sold as a “Pseudo Rice Protein”.

Archer Daniels Midland gets FDA approval for Biuret used in milk cows:

JoyD,

Thank you again for researching this information.  It will be passed on to all the list of people I have, who pass it to all their list and it goes on and on.

Everyone possible that we can warn about these poisons, is an pet we can hopefully save.

Regards,
Joanne &*Sapphire*

Frightening, this is the food we are eating and drinking.    Then we wonder why so many disorders and diseases.

Here’s something else interesting re: Non protein nitrogen feed (such as urea/biuret).

IBDU (isobutylidene diurea) is most widely as a lawn fertilizer.  But, here is a reference to its use as a feed for monogastric (non ruminant) animals.

A quote from the description of US Patent # 3984572 titled “Feed for monogastric animals” reads:

“Currently, methionine and lysine are being used as artificial feeds for monogastric animals, and urea, isobutylidene diurea and biuret are being used for ruminant animals. Among these compounds, isobutylidene diurea is excellent as an artificial feed for ruminant animals because it is gradually decomposed in the first rumen to form ammonia, whereby it can be utilized for the synthesis of microbial protein of the microorganisms inhabiting the rumen. The microbes are digested and absorbed in a digestive organ below the abomasum so as to be effective for growth of the ruminant animals. Since monogastric animals have a different digestive mechanism from ruminant animals, one of ordinary skill would not have considered that isobutylidene diurea might be effective as a feed for monogastric animals.”

This patent is for "a feed containing protein in which part of the protein is furnished by adding to said feed a urea-isobutyraldehyde condensate wherein the urea-isobutyraldehyde condensate is isobutylidene diurea. "

The inventors of this patent are:
Sakaki, Yasuhiro (Yokohama, JA)
Kawai, Hiroshi (Tokyo, JA)

The Assignee:
Mitsubishi Chemical Industries Ltd. - Aka  Mitsubishi Monsanto

All of these materials (as well as a few more) can be found in a single source. See the patent "Utilization of melamine waste effluent"

http://www.patentopedia.us/bolt_frame_construction/utilization_melamine_waste_effluent.html

Quotes from the patent:

Melamine is manufactured on a commercial scale by converting urea to melamine in several stages, including a crystallization stage which purifies the melamine to the required specifications. The mother liquor following the crystallization stage is normally stripped of ammonia and concentrated to a solids content of about 1.5-5% by weight. This final effluent stream, which is usually disposed of as waste water, contains various proportions of melamine, oxyaminotriazines, cyanuric acid, melam, melan, melon, biuret, triuret, and other higher polycondensates of urea and melamine. These various components, the percentages of which vary depending on process conditions, are considered to be the major contributors to the pollution problems of melamine manufacturing plants.

[break]

The melamine and by-products are, for the most part, contained in the mother liquor waste stream in colloidal form.
 
[break]

A ten liter sample of the mother liquor from a typical melamine manufacturing plant was filtered to recover the solids content therefrom. The solids were analyzed and were found to contain approximately 69.7% by weight of melamine, 29.7% by weight of oxytriazines (ammeline, ammelide, and cyanuric acid, collectively), and 0.6% by weight of polycondensates (melam, melem, melon, etc., collectively).

This is really interesting information . . .  Zanzie speculates . . .

So we have a non-protein nitrogen material (feed-grade biuret) which is normally added to ruminant feed to boost their protein consumption, basically by growing more bacteria in one of their 4 stomachs.  Feed-grade biuret contains melamine, cyanuric acid, amilorine, and amiloride.   

The next guy extends the concept to monogastric animals, like pigs, rabbits, dogs, cats (and us) and gets a patent for IBDU (isobutylidene diurea) use in monogastric animal nutrition. He isn't patenting the use of feed-grade biuret, but it's a step in that direction, using a urea derivative to boost protein content.

Someone in China extends the concept too far, and uses feed-grade biuret or melamine waste effluent to boost the apparent protein content of wheat gluten, rice powder and corn gluten without considering where these protein powders will end up.

Importing company in the US (e.g. Wilbur-Ellis) doesn't look too closely at the incoming ingredients from China. They're happy about the low cost. Maybe they know about the "additives", maybe not.

Protein powders containing these industrial chemicals are purchased by corner-cutting pet food processors which may or may not have looked closely at the incoming ingredients. They're looking to save a buck too.

Pet food companies have contracted out the production of their "high-value" branded products, and may or may not be aware of food processors like Menu Foods or Diamond altering the recipes or substituting lower-cost ingredients sourced from China. They'd rather not know, perhaps.

Pets consume this combination of industrial chemical additives and get violently ill.

According to recent lab studies, the reaction of melamine and cyanuric acid is rapid, and causes formation of wheel and spoke crystals, such as those seen in kidney tissue and urine of affected pets.

Perhaps IBDU has been added for a long time, and since pets weren't keeling over, we didn't know anything about it. It's possible that this only became deadly as the suppliers pushed the limits of what garbage they could put in the food before they created a deadly reaction in the pets' bodies.

Just speculating, but I could envision something like this taking place over a period of months or years.

Oh my!  That is indeed frightening.  Yes, if in milk, perhaps in baby formulas, in all sorts of things our children eat, I would imagine it might indeed contribute to autism, and all the learning disabilities that are now becoming staggeringly frequent.  I taught in special education and the classes were bursting at the seams.  In our high school the special education department was one of the largest in the high school.  There has to be a link between the escalating frequency of learning disabilities and the food we eat.  It is only common sense.
Well, we should also include the poisonous air we breath, and the poisonous water we drink.

You can add Lijun Mao's, Robert Petcavitch's, and Xiaoming Yang's patents. I have lots of research on this.

"polymer" should be a term in any query
