It can thus be concluded that gut bacteria play a role in the renal toxicity of melamine in the absence of cyanuric acid. See this image and copyright information in PMC. Melamine cyanurate is the main cause for the toxicity of melamine. All of these properties make melamine a useful building material, even if it can also be toxic in some settings. � Milk poisoning in China - In 2008, infant milk formula and other baby food was found to be contaminated with melamine and its products. The side effects of Melamine poisoning include high blood pressure, blood in urine, pain in the flank area, and a host of other problems in the urinary tract. Studies of melamine toxicity in humans and pets revealed that, although low-level exposure to the chemical does not usually cause adverse health affects, in high concentrations it crystallizes in the urine, leading to kidney stones and other renal disorders. An Aptamer-Based Biosensor for Direct, Label-Free Detection of Melamine in Raw Milk. Environ Monit Assess. Melamine has high nitrogen content, due to which it is used as a protein substitute in many food products. Therefore, when melamine combines with cyanuric acid in the ratio of 1:1, melamine cyanurate is formed. These stones were analyzed using techniques such as infrared spectroscopy, nuclear magnetic resonance, and high performance liquid chromatography. It was estimated that around 300,000 infants fell victim to melamine poisoning. Laminate flooring is toxic, because the wood-bonding adhesive and top layer contain and emit chemicals, which are harmful to our health. But why would melamine harm cats and dogs? Melamine contamination of infant formula in China and its health effects highlight the safety of the global food supply especially as it relates to formula-fed infants. [12]. This may be due to increased uric acid excretion in infants and formation of melamine-uric acid stones. Melamine foam is not toxic,because it has good physical stability and not insoluble in water, but no toxicity does not mean that can eat. [6], Melamine is also suspected have a negative effect on the functioning of the reproductive system as it possesses the ability to act as a reproductive toxicant.
