Literature has demonstrated that toxicity of melamine to dogs, cats and pigs is very low when melamine alone is added in the diet. However, the toxicity increases when animals are fed with a diet containing melamine and cyanuric acid. These compounds will cause the formation of diffuse crystals in kidney tubules which may subsequently induce renal failure. The susceptibility of poultry and ruminants to melamine is much lower. Moreover, transferring of melamine in contaminated feeds to animal tissues, milk products, and eggs has been confirmed. Previous research efforts have revealed that the duration of melamine residue in pork is very short. The residual duration of this material in other animal products is not yet available. Thus, monitoring of melamine in animal feed is vital for maintaining the health of human and animal.
