First peer-reviewed study finds BPA levels in US foods 1,000 times less than limits

WASHINGTON, Nov. 2, 2010 -- For the first time in the United States, researchers are reporting in a peer-reviewed scientific journal today detection of Bisphenol A (BPA) in fresh and canned food as well as food wrapped in plastic packaging. The amounts in the limited sample, however, were almost 1,000 times lower than the "tolerable daily intake" levels set by the U.S. Environmental Protection Agency (EPA) and the European Food Safety Authority (EFSA). Their report appears online in the American Chemical Society journal, Environmental Science & Technology.

Arnold J. Schecter and colleagues note that BPA is used in lining metal cans and in polycarbonate plastics such as baby bottles, although some manufacturers are switching to BPA-free products. "In humans, BPA is associated with cardiovascular disease, diabetes, and male sexual dysfunction in exposed workers," they state. "Food is a major exposure source. We know of no studies reporting BPA in U.S. fresh food, canned food, and food in plastic packaging in peer reviewed journals."

To fill that gap in scientific knowledge, the scientists measured BPA levels in 105 human, cat, and dog foods. They detected BPA in 63 of 105 human food samples from grocery stores in Dallas, and present a detailed list of foods, brands, and BPA levels in the text of the study. The levels were lower than the 50 micrograms per kilogram of body weight standard used by EPA and EFSA and comparable to levels detected in the past. Schecter noted that some studies have shown adverse effects associated with exposure to BPA at lower doses. "Further research is indicated to determine BPA levels in U.S. food in larger, representative sampling," the report said.

Chemicals used to replace BPA may lead to increased blood pressure
Common bisphenol A (BPA) substitutes can affect the developing fetus and cause hypertension in later life, suggests a rodent study accepted for presentation at ENDO 2020, the Endocrine Society's annual meeting.

Think all BPA-free products are safe? Not so fast, scientists warn
Using 'BPA-free' plastic products could be as harmful to human health -- including a developing brain -- as those products that contain the controversial chemical, suggest scientists in a new study led by the University of Missouri and published in the Proceedings of the National Academy of Sciences.

BPA's counterpart replacement BPS can hinder heart function within minutes of a single exposure, according to a new University of Guelph study.

Study finds BPA levels in humans dramatically underestimated
Researchers have developed a more accurate method of measuring bispehnol A (BPA) levels in humans and found that exposure to the endocrine-disrupting chemical is far higher than previously assumed.

Bisphenol-a structural analogues may be less likely than BPA to disrupt heart rhythm
Some chemical alternatives to plastic bisphenol-a (BPA), which is still commonly used in medical settings such as operating rooms and intensive care units, may be less disruptive to heart electrical function than BPA, according to a pre-clinical study that explored how the structural analogues bisphenol-s (BPS) and bisphenol-f (BPF) interact with the chemical and electrical functions of heart cells.

BPA exposure during pregnancy can alter circadian rhythms
Exposure to the widely used chemical bisphenol A (BPA) during pregnancy, even at levels lower than the regulated 'safe' human exposure level, can lead to changes in circadian rhythms, according to a mice study to be presented Monday at ENDO 2019, the Endocrine Society's annual meeting in New Orleans, La.

Can prenatal exposures to BPA impact ovarian function?
While previous studies have shown the adverse health effects of prenatal exposure to the industrial chemical bisphenol A (BPA), there is little evidence surrounding effects specifically on ovarian function.
