 FDAその他の健康機関は、BPAビスフェノールAの健康への影響を明らかにするために、3000万ドルを投入して、短期・長期の研究を行うと表明している。哺乳瓶を含めたプラスチック製品に含まれ、最近の研究で健康や発達に影響を及ぼす可能性が指摘されている。
 最近の報告では低容量で動物に微妙な影響を及ぼすことがわかり、FDAでも懸念を表明することになり、発達早期に暴露を受ける子どもへの影響を研究する必要がでてきた。
 米国内向けの哺乳瓶の90%にはすでにBPAは含まれていないという。最近2年間に発表された研究によれば、心臓病、性機能障害、がん、糖尿病、多動、女児の攻撃性と関連があるとされている。さらに胎児発育にも影響している可能性がある。
 NTP米国毒物学プログラム2008によれば、最新データによりFDAレポートよりも懸念が高まりFDAを批判することとなった。胎児・乳幼児・子どもの脳・行動・前立腺への影響がいくらかあると表明された。

 消費者がBPA暴露を減らすための方法:
*小児科学会推奨のように、可能ならば12ヶ月までの母乳哺育。鉄を強化したミルク。
*BPA哺乳瓶の処分。
*哺乳瓶にあまり熱いミルクを入れない。
*電子レンジや食洗機対応のラベルの確認。

Health Agencies Express Concern Over BPA
HHS, FDA pledge funds for more research on the common plastics chemical

画像FRIDAY, Jan. 15 (HealthDay News) -- The U.S. Food and Drug Administration and other U.S. health agencies are pledging $30 million toward short- and long-term research aimed at clarifying the health effects of the plastics chemical bisphenol A (BPA).

The chemical is ubiquitous in plastic products, including baby bottles and sippy cups, as well as metal linings of some cans, including those containing infant formula. And it has come under close scrutiny in the past year or two with studies linking it to a host of health and developmental problems.

"Recent reports show subtle effects of low doses of BPA in laboratory animals and that has raised concerns so we now are taking a much closer look at BPA," said Bill Corr, deputy secretary of the U.S. Department of Health and Human Services (HHS), the umbrella organization for the U.S. Food and Drug Administration and other agencies. "We need more research to understand the potential effects on children," he said.

Corr and other officials spoke at a Friday afternoon news conference.

The FDA stopped short of stating that it was raising its level of concern about the chemical.

"BPA has not been proven to harm either children or adults," Corr said. "But the data deserves a much closer look because children are being exposed at early states of development."

"In a word, FDA does support the use of bottles with BPA because the benefit of nutrition outweighs the potential of risk of BPA," said Dr. Joshua Sharfstein, principal deputy commissioner of the FDA. "If we thought it was unsafe, we would be taking strong regulatory action."

Sharfstein added that 90 percent of baby bottles manufactured for the U.S. market no longer contain BPA.

In studies released over the past two years, BPA has been linked to heart disease, sexual dysfunction, cancer, diabetes and hyperactivity, as well as aggression in girls. There is also concern that it could have an effect on the developing fetus.

According to FDA Commissioner Dr. Margaret Hamburg, the agency "shared the perspective of the National Toxicology Program of some concern of health effects of BPA."

The National Toxicology Program's 2008 report on BPA used more current data and raised more concern than an FDA report on BPA, leading to criticism of the FDA document.

In the NTP report, experts expressed "some concern for effects on the brain, behavior, and prostate gland in fetuses, infants, and children at current human exposures to bisphenol A."

"What's happening today is the FDA is saying that our perspective is now in line with [the NTP assessment]," Scharfstein said. "We have some concern in areas they had some concern and are taking action based on that level of concern to understand more about BPA."

Sharfstein said the agency was also looking also at new regulatory frameworks for BPA, so that officials could act more quickly on the chemical if warranted.

Until the agencies "answer key question and clarify uncertainties about BPA," the FDA is "taking reasonable steps to reduce human exposure to BPA, supporting industry's action to remove BPA from baby bottles and cups, facilitating alternatives to BPA for lining of cans, and supporting efforts to remove or minimize BPA in other food can linings," Hamburg said.

Corr detailed four steps that consumers can take to reduce their BPA exposure:

* As recommended by the American Academy of Pediatrics, babies should be breast-fed for 12 months if possible. The safest and most nutritious alternative is iron-fortified infant formula, even if there are trace amounts of BPA.
* Discard scratched baby bottles and cups as they may harbor germs and may release small amounts of BPA.
* Very hot infant formula should not be put into BPA-containing bottles as BPA could leach from the container to the food.
* Check labels of all bottles and cups to make sure they are microwave and dishwasher safe.
