BPA activates immune response in mice that passes down through generations

Some plastic food and beverage containers still contain bisphenol A (BPA), which can mimic the hormone estrogen. Although experts say that small amounts of BPA detected in foods are unlikely to cause problems, some people worry that constant low-level exposures could have health effects, especially for developing fetuses, infants and children. Now, researchers report that in mice, BPA activates an immune response that persists for at least three generations.
