Industrial heavy metal waste in Chinese animal feed

Chemistry for crooked cats

The Council of Agriculture (COA) in China announced yesterday that the country’s largest processor of waste copper liquids illegally sold toxic, industrial-grade copper sulfate to at least four livestock feed manufacturers. At least one of those companies did not have a license to produce animal feed in the first place.

They found that industrial heavy metals such as copper sulfate, also known as cupric sulfate, had been mixed with feed for pigs, chickens, ducks and geese which had found its way to farmers all over the country, a practice which could leave heavy metal residues in the animal tissue, the officials said.

Prosecutors said they believe that contaminated livestock and poultry have already entered the market. An official of the Chinese environmental protection agency said if humans eat meat that contains industrial-grade copper, the outcome is “bad to imagine”.I know nuttin bout chemistry, but at least I look good doin it.

The industrial-grade copper sulfate the company sold was recycled from circuit boards in the electric industry for use in printing ink and batteries. Officials said in one of the four feed processors they found 100 ppm of lead per kilogram in the feed.

The company was raided after the council received a local tip-off last December of an alleged case of improper wastewater treatment for illegally disposing of hazardous waste material. The company processed waste supplied by unlicensed companies and was cited for violating numerous environmental laws for illegally disposing of heavy metal waste into the environment.

Officials are currently investigating the extent and duration the company has been illegally selling industrial waste to feed companies and the number of livestock and poultry that consumed the contaminated feed.I shoulda payed more attentun in skool, cuz earth metals comfuzes me.

Copper sulfate is a versatile heavy metal that comes in three grades: industrial, agricultural and feed.

Industrial and agricultural formulations of copper sulfate can be cheaper, but industrial-grade copper sulfate is a highly toxic agent that, when ingested, can cause local and systemic damage including coma, shock, severe intravascular hemolysis, hepatotoxicity and acute renal failure with high mortality. The effect copper sulfate on the renal system is kidney abnormalities after copper sulfate ingestion, acute tubular necrosis was observed on urinanylisis and renal biopsy.

In August last year a report surfaced that dioxin contaminated copper sulfate was being sold as a feed additive in Europe. The Rapid Alert System for Feed and Food (RASFF) operated by the EU reported the presence of contaminated of copper sulfate allegedly originating in Romania. This case follows similar instances of dioxin and heavy metal contamination of copper sulfate derived from China. And another in which arsenic was found in copper sulfate sold as a feed additive allegedly originating from Poland.Fluffy - he's got da brainz in da famiwy.

Generally dioxin contamination of copper sulfate occurs when recycled copper wire is melted to recover elemental copper which is then reacted with sulfuric acid to derive copper sulfate which is incorporated into premixes.  In the process of smelting recycled copper wire, plastic insulation is pyrolized and contaminates copper with the degradation products of plastic including dioxins. The maximum level of dioxin in feed is set in the EU at 1ppt (one part per trillion or 1 nanogram/kg).

The most recent episode emphasizes the need for quality control of all ingredients used in diets. Trace quantities of dioxin and PCB/PBB contamination in feed premixes can result in widespread recalls following detection of contaminants in the food chain which is now possible using sensitive and sophisticated analytical equipment operated by regulatory agencies in industrialized nations.Now, whut was it my professur sed bout radio active waste? Sumptin bout reception, I fink.

The maximum level for unwanted substances in feed in the EU can be found in the recently updated Directive on Undesirable Substances in Animal Feed (2002/32/EU).

The values for dioxin can be found in Section V of Commission Regulation no. 574/2011.

The dioxin contaminated copper sulphate was distributed to Belarus, Belgium, Dominican Republic, France, Morocco, Netherlands and Syria. More information on the notification can be found in Rapid Alert Safety for Feed and Food (RASFF)

  1. This is why even the Chinese in there years of a baby boom{year of the dragon) do not trust baby food and products from there own country, and why we need to put muscle back into USDA inspections and authority to keep manufactures honest not only thru imports but in the USA as well. If people think that they can get away with cutting corners for the sake of money even at the risk of others they will do it.

  2. If you think the dog food is a problem, just wait. I heard that Cargill will be sourcing chickens to McDonald’s in the US!! Poison our children next?? We need to STOP this food from China. It is a toxic place!!

  3. YEP..I am done with CHINA. The chicken jerky strips and other stuff is enough for me. I will not buy another food product for sure. and i am going to start paying attention to everything else. I have had enough!!!!!! i am pissed also that the FDA is sitting on there asses on these pet treats. Dogs are dying ever day. and no one gives a shit that should!!! and I know…us humans are being poisoned too… Hell i dont even trust organic food much anymore. This is why people die of cancer..we are slowly being killed!!!!

  4. If China keeps doing this stuff poison dog treats, lead paint on kids toys, now this and probably a lot more they are going to doom their selves. People are not going to trust anything from China and not buy if made in China.new trend “if the tag says made in China don’t buy” lol

  5. I believe that this is evidence of the toxic and poison pet food and treats that are coming from China and still out there on the shelves!!! Check out http://www.fda.gov. Then click on animal/veterinary alerts recalls. Thanks for posting! I am definitely sharing!

  6. Well we certainly know there is again something toxic in Chinese dog treat products. This would explain a lot”

    • It certainly “looks” bad. Now, just how a pet or human ingesting the meat or poultry that were fed the contaminated feed might be affected – is an unknown, to me at least. I’m not a toxicologist, I just report the news, and let the public decide for themselves if they want to continue buying products made in China or products that contain ingredients from China.

  7. your cat people are creepy. LOL. So…if the CJTs from China are made from fowl that ate this heavy metal feed…could this be the culprit?

    • It sure doesn’t look good…It could be a smoking gun or it could be a sign the FDA better get off their ass and test for heavy metals instead of dickin around with DNA testing and other stupid shit that has nothing to do with acute renal failure…Just sayin…
