All products from China containing more than 15% milk as an ingredient, or products where the percentage of milk content cannot be established, will be subject to documentary, identity and physical checks, including laboratory analysis, to determine that any levels of melamine present in the product do not exceed 2.5 mg/kg. Those products with more than 2.5mg/kg will be destroyed.

NZFSA has adopted a conservative threshold of 5 ppm for most foods. This means that it has been considered that foods containing up to 5 ppm of melamine do not pose a risk to human health. However for starter infant formula, this level will be set to the current level of test detection of 1 ppm.

Melamine

The metabolism, excretion and disposition of melamine was assessed after oral administration of a single dose of 0.025 mCi (0.38 mg) [14C] melamine to adult male Fischer 344 rats. Overall, 90 % of the administered dose was excreted within the first 24 hours into urine and negligible radioactivity appeared in the exhaled air and the faeces. Virtually no residual radioactivity was observed in tissues examined after 24 hours. Only slight differences in levels of radioactivity between blood, liver or plasma were observed, suggesting that melamine is distributed in the body water.

So it is possible that the melamine accumulates in the body water, including blood?

Pharma. Industry
Be scientific and be fair.

Hi,

Please ask people working in the pharmaceutical factory about

"What is analytical method validation", and you will know what is detect limit and quantization limit. To containminate with unintented matter is wrong, but be scientific to face true problem.

The scientist could not get him(her)self away from the normal daily life. It is immoral to let politicians to manipulate and contaminate science.
