After talking to a guy yesterday I thought this would make for interesting reading.
He seemed to know what he was talking about. Seems that a major milk supplier in SA is using Melamine to increase false protein ratings:
1. What is melamine?
Melamine (also known as tripolycyanamide) is an industrial chemical used for the production of melamine resins, which are used in laminates, glues, adhesives, molding compounds, coatings, paper, textiles, flame retardants or superplastisizer for concrete.
2. How did melamine get into infant formula?
The adulterant melamine was added to the milk to cause a false increase in the measurement of protein for dairy products. It is not allowed to be added to food in any quantity.
3. What is the toxicity of melamine?
Melamine has low oral acute toxicity. However, excessive exposure to melamine has been found to cause urinary stones in experimental animals. Laboratory studies showed that melamine did not damage genetic materials in cells. There was also inadequate evidence to show that melamine can cause human cancers.
4. How were infants being affected by melamine containing infant formula?
Recently, tens of thousands of infants in the Mainland who have consumed Sanlu infant formula are suffering from renal disease, including urinary stones, conditions of which are rare in infants. Infants are more susceptible to urinary stones formation because milk is their major food, the amount of melamine intake per body weight is much higher than that of adult who consumes a variety of foods. Also, it was found that Sanlu infant formula contained especially high level of melamine (up to 2563 mg/kg) that may affect the elimination of the chemical from the body.
5. What are the clinical presentations of the development of urinary stone after the consumption of melamine containing infant formula in infants?
The clinical presentations included irritability, blood in urine, little or no urine, stone in urine, pain and difficulty in urination, and high blood pressure etc.
6. How are adults being affected by the consumption of melamine containing milk?
Based on Mainland’s situation, over 99% of victims affected by consumption of melamine containing milk were below three years old. As the sensitivity towards melamine is lower and milk is not a major food source of adults, the health risk of adults in consuming melamine containing milk is lower.
7. What are the health effects of melamine to pregnant women and fetus?
Based on Mainland’s situation, over 99% of victims affected by consumption of melamine containing milk were below three years old. There is currently no human data available on the health effects to pregnant women and fetus. Available animal studies did not show evidence that it would produce defects in developing fetus.
8. What are the health effects of melamine to elderly?
Based on Mainland’s situation, over 99% of victims affected by consumption of melamine containing milk were below three years old. There is currently no human data available on the health effects of melamine to elderly. However, milk only constitutes a part of the total food consumed by the adult population and the risk is relatively low.
9. What are the health effects for consumption of food containing melamine for a long period of time?
There is currently no human data available regarding consumption of food containing melamine for a long period of time. Information based on data from animal studies showed that melamine is rapidly cleared from the body. However, based on Mainland’s information, over 99% of victims affected by consumption of melamine containing milk were below three years old; majority of them was affected three to six months after the consumption of contaminated milk.
10. What products were found to contain melamine in the Mainland?
The list of products that were found to contain melamine and their manufacturers is posted on the website of the General Administration of Quality Supervision Inspection and Quarantine of People’s Republic of China. Consumers can check with the official website for updated information.
11. Are those melamine contaminated infant formula including the Sanlu formula and those formula tested with melamine by the Mainland available in Hong Kong?
No, they are not found to be available in Hong Kong . People who have purchased the product outside Hong Kong should stop consuming the product immediately.
12. Has melamine been found in any infant formula, other dairy products or food products available locally?
The CFS has taken from the local market samples of infant formula and other milk-made products, such as fresh milk, ice-cream, ice-cream bars, yogurt, baby food, nutrition supplements for hospital use, instant drink mixes, biscuits, cakes, bread, chocolate and candies etc. for tests. As at 30 October 2008, a total of 39 samples of 18 brands of food products were found to contain unsatisfactory amount of melamine ranging from 1.4ppm to 68ppm. The sample results are available in the web site of CFS, www.cfs.gov.hk. The highest level of melamine was detected in one biscuit sample. All the affected products are being off shelves and withdrawn from the market. CFS will continue to monitor the situation closely.
