In high concentrations, melamine contamination can put people at risk for kidney stones, kidney failure and even death. On March 15, 2007, pet food manufacturer Menu Foods alerted FDA to 14 animal deaths in the United States: 4 cats and 1 dog reported by consumers, and 9 cats that … Products with melamine contamination above the levels noted in FDA’s risk assessment may put people at risk of conditions such as kidney stones and kidney failure, and of death. Melamine has high nitrogen content, due to which it is used as a protein substitute in many food products. This type of resin is made by mixing melamine with formaldehyde, and sometimes urea, under heat and pressure. It was estimated that around 300,000 infants fell victim to melamine poisoning. Page 5 of 6 MSDS ± Melamine Special Remarks on other Toxic Effects on Humans: Acute Potential Health Effects: Skin: May cause skin irritation. Various veterinary organizations reported more than 100 pet deaths and almost 500 cases of kidney failure. it’s the most widely used material for modern furniture. Melamine Faced Chipboard is a standard melamine board. When melamine cyanurate is ingested through food or through contaminated plastic utensils, it is circulated throughout the body. A simple magnetic solid-phase extraction method based on magnetite/graphene oxide nanocomposite for pre-concentration and determination of melamine by high-performance liquid chromatography. However, new research is shedding light on just how much damage can be done to the human body from ingesting melamine. Therefore, melamine cyanurate keeps getting accumulated in the kidneys to a large extent, and forms crystallized stones. Pet food containing corn gluten was also found to be contaminated with melamine. Cyanuric acid was detected in the kidneys of rats administered melamine alone, and the concentration after Klebsiella colonization was increased. The rats which were affected by melamine toxicity were then subjected to treatment with naturally-produced honey produced by honeybees at a dosage of 2.5g/kg of body weight for a period of 28 days. Melamine had been added as a protein substitute to infant milk formula, owing to its high nitrogen content. A: I’m a polymer chemist (30 years or so in the lab, sales, product development and marketing) by day and a woodworker on the weekends and by night. 2020 Mar;27(9):9826-9834. doi: 10.1007/s11356-020-07681-z. [7], Analytical tests for detecting the presence of melamine cyanurate in food, Some of the analytical tests used for detecting the presence of the toxic substance melamine cyanurate in foods are as follows - [8] [9], → Gas Chromatography - Mass Spectrometry (GC-MS), → High Performance Liquid Chromatography (HPLC), → Hydrophilic Interaction Liquid Chromatography (HILIC), → Triple Quadrupole Liquid Chromatography (TQLC), → Electrospray Ionization coupled with Mass Spectrometry (ESI-MS), → High Performance Liquid Chromatography - Electrospray Ionization - Tandem Mass Spectroscopy (HPLC - ESI - MS/MS), → Ultrasound-Assisted Extractive Electrospray Ionization Mass Spectrometry, → Surface Enhanced Raman Spectroscopy (SERS), → High Performance Liquid Chromatography - Tandem Mass Spectroscopy, → Enzyme Linked Immuno Sorbent Assay (ELISA), → "Direct analysis in real time" ion source coupled to Time-of-Flight Mass Spectroscopy (TOFMS), → High Performance Liquid Chromatography - Time-of-Flight Mass Spectroscopy (HPLC-TOFMS), → Fourier Transform Infrared (FTIR) microscopy, → Proficiency Test in a milk matrix used for testing infant milk formula, SYMPTOMS AND EFFECTS OF MELAMINE TOXICITY [10] [11], Nephrolithiasis (kidney stones) with melamine crystalluria, Elevation in Blood Urea Nitrogen (BUN) and creatinine levels, Nephrosis (degeneration of renal tubules), Decrease in levels of free-radical scavenging enzymes. Melamine is also used for making plastics. Gribble K, Berry N, Kerac M, Challinor M. Matern Child Nutr. It also adds strength, and can help resist bacterial or fungal colonization. Melamine is categorized under Class #7 on the list of Plastic Resin Codes. An EU classification of melamine for being specific organ toxic and carcinogenic is recently under discussion. The toxic compound in apricot kernels is cyanide 2 3 6.One apricot kernel contains about 0.5 milligram of cyanide, according to Internet Scientific Publications 2.Cyanide is a chemical gas that's poisonous and prevents your body from properly absorbing oxygen. Epub 2020 Jan 11. ♦ Elevations in serum concentrations of enzymes such as alanine transaminase and aspartate transaminase, ♦ Rise in levels of nitrogenous compounds such as creatinine and uric acid, The following adverse carcinogenic effects were observed -, ♦ Development of uroliths (urinary bladder stones), ♦ Hyperplasia (increase in cell proliferation) of urinary bladder epithelium, ♦ Inflammation of kidney and urinary bladder. Laminate flooring is toxic, because the wood-bonding adhesive and top layer contain and emit chemicals, which are harmful to our health. 2017 Jul;13(3):e12388. Clinical signs and symptoms in infants are nonspecific. [1], Synthesis of melamine - Melamine is synthesized from urea, at a temperature of 350-400oC, under -, → High Pressure liquid phase (90-150 bar pressure), or, → Low Pressure gaseous phase (1-10 bar pressure). TEL: 0086-592-5885628 E-MAIL: master@kingwellcn.com.cn These stones were analyzed using techniques such as infrared spectroscopy, nuclear magnetic resonance, and high performance liquid chromatography. In the test group, rats were given a dosage of antibiotics for four days (so as to eliminate gut bacteria), followed by a two-week dosage of melamine. Q: What pet foods are recalled? In particular, Klebsiella terrigena was determined to be a factor in melamine toxicity. Skin contact may occur, but does not cause any problems, apart from rare cases of irritation. However, greater research needs to be carried out in greater detail to understand if these carcinogenic effects can develop into full-fledged malignancy. Infants are more susceptible to melamine poisoning, and using melamine cups to serve formula and milk should be avoided. 16 infants were diagnosed with kidney stones, owing to consumption of melamine. Enworld Brand Melamine Foam Sponge Is Nontoxic To Fish Enworld melamine foam sponge manufacturer’s cleaning product is nontoxic to fish, because our melamine foams themselves are merely stains removal cleaning tools. 2018 Jan;25(3):2285-2292. doi: 10.1007/s11356-017-0658-y. Melamine dishware is generally considered safe, since melamine does not migrate into most foods. Recycling Melamine Dinnerware is Difficult. [15], After three days of feeding, melamine and cyanuric acid started showing the following toxic effects -. Treatments for kidney damage caused by melamine toxicity - [19], → Intravenous fluids and dialysis to remove melamine from kidneys, → Fluid intake should be carefully monitored, → Medication for controlling blood pressure, nausea, anemia, → Kidney function tests for monitoring progression of treatment, Treatments for reproductive damage caused due to melamine toxicity - [20], → Avoidance of teratogenic agents which can affect the growth and development of the foetus, → Banning of medications which can affect reproductive health, [1] http://jasn.asnjournals.org/content/20/2/245.full, [2] http://www.who.int/foodsafety/fs_management/Melamine_2.pdf, [3] http://upload.wikimedia.org/wikipedia/commons/0/05/Melamine.svg, [4] http://wiki.answers.com/Q/What_are_the_properties_of_melamine, [5] http://en.wikipedia.org/wiki/Melamine_cyanurate, [6] http://voices.yahoo.com/what-causes-melamine-poisoning-7603868.html, [7] http://www.rightdiagnosis.com/r/reproductive_toxicity_melamine/intro.htm#whatis, [8] http://en.wikipedia.org/wiki/Melamine#Testing_in_food, [9] http://food.eurofins.com/melamine.aspx, [10] http://www.poisons.co.nz/fact.php?f=43, [11] http://www.rightdiagnosis.com/r/reproductive_toxicity_melamine/intro.htm, [12] http://en.wikipedia.org/wiki/2008_Chinese_milk_scandal, [13] http://en.wikipedia.org/wiki/2007_pet_food_recalls, [14] http://news.sciencemag.org/2013/02/gut-bacteria-conspired-melamine-poisonings, [15] http://www.hindawi.com/journals/bmri/2013/786051/, [16] http://tih.sagepub.com/content/28/7/579.abstract, [17] http://www.ncbi.nlm.nih.gov/pubmed/22316434, [18] http://www.ncbi.nlm.nih.gov/pubmed/6695376, [19] http://www.medindia.net/patients/patientinfo/kidney-failure-due-to-melamine-toxicity.htm, [20] http://www.rightdiagnosis.com/r/reproductive_toxicity_melamine/treatments.htm, Solid Phase Extraction Liquid Chromatography - Mass Spectrometry.
