Even Small Doses Of BPA Can Harm Ovaries

The bad news about BPA just keeps coming.

We know the hormone-disrupting chemical leaches into our food and water through plastics, the linings of food and beverage cans and other household items. Over 90 percent of Canadians have BPA present in their bodies. The specter of BPA exposure is a huge stress for pregnant women.

But does it do any real harm? Industry lobbyists would like us to believe the chemical is safe for humans, but science just keeps turning up more evidence that it’s not.

A new study from Washington State University shows that even extremely small doses of BPA affect the ovaries of female mice. It takes only 12 hours for BPA to disrupt the formation of eggs and alter their ability to pass on genetic information.

That affects not only the lady mouse with the BPA exposure, but her children and grandchildren.

The disruption to egg creation in the mouse’s ovaries can lead to a host of problems for her offspring and theirs. For the first generation after BPA exposure, the altered ovaries may produce fewer eggs, leading to fertility problems and potentially early menopause. For the grandchildren of the original mouse, the malformed eggs can cause birth defects.

The levels of BPA the mice were exposed to were similar to those typically carried in people, the researchers said.

Can we get this nasty toxin out of our food supply already?

Until the government acts to get rid of it, your best bet for avoiding BPA exposure is to steer clear of any food or drink container with a #7 recycling code on it. You also want to avoid canned foods or drinks. Be wary of hand-me-down baby bottles and gear. Until two years ago many baby items and toys were made from BPA.
