By MARTHA MENDOZA and JUSTIN PRITCHARD – 26 minutes ago
Traces of the industrial chemical melamine have been detected in samples of top-selling U.S. infant formula, but federal regulators insist the products are safe.
The Food and Drug Administration said last month it was unable to identify any melamine exposure level as safe for infants, but a top official said it would be a "dangerous overreaction" for parents to stop feeding infant formula to babies who depend on it.
"The levels that we are detecting are extremely low," said Dr. Stephen Sundlof, director of the FDA's Center for Food Safety and Applied Nutrition. "They should not be changing the diet. If they've been feeding a particular product, they should continue to feed that product. That's in the best interest of the baby."
Melamine is the chemical found in Chinese infant formula — in far larger concentrations — that has been blamed for killing at least three babies and making at least 50,000 others ill.
Previously undisclosed tests, obtained by The Associated Press under the Freedom of Information Act, show that the FDA has detected melamine in a sample of one popular formula and the presence of cyanuric acid, a chemical relative of melamine, in the formula of a second manufacturer.
Separately, a third major formula maker told AP that in-house tests had detected trace levels of melamine in its infant formula.The three firms — Abbott Laboratories, Nestle and Mead Johnson — manufacture more than 90 percent of all infant formula produced in the United States.
The FDA and other experts said the melamine contamination in U.S.-made formula had occurred during the manufacturing process, rather than intentionally.The U.S. government quietly began testing domestically produced infant formula in September, soon after problems with melamine-spiked formula surfaced in China.
Sundlof said there have been no reports of human illness in the United States from melamine, which can bind with other chemicals in urine, potentially causing damaging stones in the kidney or bladder and, in extreme cases, kidney failure.
Melamine is used in some U.S. plastic food packaging and can rub off onto what we eat; it's also contained in a cleaning solution used on some food processing equipment and can leach into the products being prepared.
Sundlof told the AP the positive test results "so far are in the trace range, and from a public health or infant health perspective, we consider those to be perfectly fine."
That's different from the impression of zero tolerance the agency left on Oct. 3, when it stated: "FDA is currently unable to establish any level of melamine and melamine-related compounds in infant formula that does not raise public health concerns."
FDA scientists said then that they couldn't set an acceptable level of melamine exposure in infant formula because science hadn't had enough time to understand the chemical's effects on infants' underdeveloped kidneys. Plus, there is the complicating factor that infant formula often constitutes a newborn's entire diet.
The agency added, however, that its position did not mean that any exposure to a detectable level of melamine and melamine-related compounds in infant formula would result in harm to infants.
Still, the announcement was widely interpreted by manufacturers, the news media and Congress to mean that infant formula that tested positive at any level could not be sold in the United States.
The Grocery Manufacturers Association, for example, told its members: "FDA could not identify a safe level for melamine and related compounds in infant formula; thus it can be concluded they will not accept any detectable melamine in infant formula."
It was not until the AP inquired about tests on domestic formula that the FDA articulated that while it couldn't set a safe exposure for infants, it would accept some melamine in formula — raising the question of whether the decision to accept very low concentrations was made only after traces were detected.
On Sunday, Sundlof said the agency had never said, nor implied, that domestic infant formula was going to be entirely free of melamine. He said he didn't know if the agency's statements on infant formula had been misinterpreted.
In China, melamine was intentionally dumped into watered-down milk to trick food quality tests into showing higher protein levels than actually existed. Byproducts of the milk ended up in infant formula, coffee creamers, even biscuits.
The concentrations of melamine there were extraordinarily high, as much as 2,500 parts per million. The concentrations detected in the FDA samples were 10,000 times smaller — the equivalent of a drop in a 64-gallon trash bin.
There would be no economic advantage to spiking U.S.-made formula at the extremely low levels found in the FDA testing. It neither raises the protein count nor saves valuable protein, said University of California, Davis chemist Michael Filigenzi, a melamine detection expert.
According to FDA data for tests of 77 infant formula samples, a trace concentration of melamine was detected in one product — Mead Johnson's Infant Formula Powder, Enfamil LIPIL with Iron. An FDA spreadsheet shows two tests were conducted on the Enfamil, with readings of 0.137 and 0.14 parts per million.
Three tests of Nestle's Good Start Supreme Infant Formula with Iron detected an average of 0.247 parts per million of cyanuric acid, a melamine byproduct.And while the FDA said tests of 18 samples of formula made by Abbott Laboratories, including its Similac brand, did not detect melamine, spokesman Colin McBean said some company tests did find the chemical. He did not identify the specific product or the number of positive tests.McBean did say the detections were at levels far below the health limits set by all countries in the world, including Taiwan, where the limit is 0.05 parts per million.
"We're talking about trace amounts right here, and you know there's a lot of scientific bodies out there that say low levels of melamine are always present in certain types of foods," said McBean.
Mead Johnson spokeswoman Gail Wood said her company's in-house tests had not detected any melamine, and that the company had not been informed of the FDA test results, even during a confidential agency conference call Monday with infant formula makers about melamine contamination.
The FDA tests also detected melamine in two samples of nutritional supplements for very sick children who have trouble digesting regular food. Nestle's Peptamen Junior medical food showed 0.201 and 0.206 parts per million of melamine while Nestle's Nutren Junior-Fiber showed 0.16 and 0.184 parts per million.
The agency said that while there are no established exposure levels for infant formula, pediatric medical food — often used in feeding tubes for very sick, young children — can have 2.5 parts per million of melamine, just like food products other than infant formula.
In a written response to questions, a Nestle spokesman denied that any of the company's products contained cyanuric acid, and said its products are safe.
Rep. Rosa DeLauro, D-Conn., who heads a panel that oversees the FDA budget, said the agency was taking a "marketplace first, science last" approach.
"The FDA should be insisting on a zero-tolerance policy for melamine in domestic infant formula until it is able to determine conclusively based on sound independent science that the trace levels would not pose a health risk to infants," DeLauro said.
Rep. Bart Stupak, D-Mich., a frequent critic of the FDA, said: "If no safe level of melamine has been established for consumption by children, then the FDA should immediately recall any formula that has tested positive for even trace amounts of the contaminant."
Several medical experts said trace concentrations would be diluted even in an infant, and are highly unlikely to be harmful.
"It's just a tiny amount, it's very unlikely to cause stones," said Stanford University Medical School pediatrics professor Dr. Paul Grimm.
Dr. Jerome Paulson, an associate professor of pediatrics at Children's National Medical Center in Washington, D.C., said he didn't think the FDA's decision was unreasonable. He added, however, that the agency should research the impacts of long-term, low-dose exposure, "and not just assume it's safe, and then 15 years from now find out that it's not."
