Warning about chemical found in plastic bottles and food containers

Apr 17 2008

A chemical used to make plastic bottles and other food containers, is suspected to be linked to hormonal and neurological problems.

Bisphenol A (BPA) is used in the production of polycarbonate plastics and epoxy resins and can be found in food and drink packaging as well as compact discs; some medical devices, dental sealants or composites also contain it.

BPA is also used in many plastic baby bottles and the plastic lining of cans of infant formula.

The United States Health Department's National Toxicology Program (NTP) has released a preliminary report on Bisphenol A which expresses concern for neural and behavioral effects in fetuses, infants and children, at current human exposures.

According to the NTP there is also some concern for Bisphenol A exposure in these populations based on effects in the prostate gland, mammary gland, and an earlier age for puberty in females.

The NTP says laboratory rodents exposed to BPA levels similar to human exposures developed pre-cancerous lesions in the prostate and mammary glands, among other things and the possibility that Bisphenol A may impact on human development cannot be dismissed.

The NTP also says the research only provides limited evidence for adverse effects on development, and more research is needed to better understand the implications for human health.

The chemical is common in containers used for food, dishes and food storage containers meant for use in microwaves.

Environmental activists have previously warned about health concerns regarding the chemical and have welcomed the draft findings of the National Toxicology Program.
