Bisphenol A (BPA) was banned from plastic baby bottles and children's cups in 2012, because it is an "endocrine disrupter," or a chemical with estrogenic activity (EA). These chemicals have been linked to a host of medical issues, including:

• Early puberty in femals
• Reduced sperm counts
• Altered functions of reproductive organs
• Obesity
• Altered sex-specific behaviors
• Increased rates of some breast, ovarian, testicular and prostate cancers

Unborn and infant babies, as well as young children, are especially susceptible to the effects of these chemicals.

Removing BPA from some plastics is a token victory, however. The chemicals replacing BPA in plastics - even baby bottles and children's cups - are just other EA chemicals. A 2011 study of over 500 plastics from national retailers concluded that almost all of the pieces tested released endocrine disrupters.

It is the responsibility of the Food and Drug Administration to recognize that these chemicals are not safe - especially for pregnant women, babies and toddlers - and that EA-free alternatives are readily available to the plastics industry, by banning EA chemicals from plastics production.

"BPA free" means nothing. Our children and families need "EA free" plastics.
