The U.S. Food and Drug Administration (FDA) has issued the results of its interim safety and risk assessment of melamine and melamine-related compounds in food, including infant formula.
A safety/risk assessment is a scientifically based methodology used to estimate the risk to human health from exposure to specified compounds. It is based on available data and certain scientific assumptions in the absence of data. The purpose of the FDA interim safety/risk assessment was to identify the level of melamine and melamine-related compounds in food which would not raise public health concerns. The interim safety/risk assessment evaluated the melamine exposure in infant formula and in other foods.
The safety/risk assessment, prompted by reports of melamine contamination of milk-derived ingredients and finished food products containing milk manufactured in China, was conducted by scientists from FDA's Center for Food Safety and Applied Nutrition and the Center for Veterinary Medicine. The FDA reviewed scientific literature on melamine toxicity.
Infant Formula
FDA is currently unable to establish any level of melamine and melamine-related compounds in infant formula that does not raise public health concerns. In large part, this is because of gaps in our scientific knowledge about the toxicity of melamine and its analogues in infants, including:
- the consequences of the continuous use of infant formulas as the sole source of nutrition;
- the uncertainties associated with the possible presence and co-ingestion of more than one melamine analogue; and
- for premature infants with immature kidney function, the possibility that they may be fed these formulas as the sole source of nutrition and thus on a body weight basis experience greater levels of intake for a longer time than is experienced by term infants.
There is too much uncertainty to set a level in infant formula and rule out any public health concern. However, it is important to understand that this does not mean that any exposure to any detectable level of melamine and melamine–related compounds in formula will result in harm to infants.
