Recent studies by C.Q. Gao and co-authors add new data to chemicals and chemistry findings.

Researchers detail in 'Toxicity of dietary melamine to laying ducks: biochemical and histopathological changes and residue in eggs,' new data in chemicals and chemistry. "Jinding laying ducks (n=648) were subjected to one of six dietary treatments (0, 1, 5, 25, 50, or 100 mg of melamine/kg of diet) to investigate the toxicity of melamine and determine the melamine residue in eggs. Ducks were fed melamine-supplemented diets for 21 days followed by a 21 day withdrawal period," scientists in Beijing, People's Republic of China report.

"Dietary melamine had no adverse effects on laying performance. Renal lesions were correlated with increasing levels of dietary melamine. Melamine …
