Commissioner for Health, John Dalli, has justified the ban by the need to "better protect the health of EU citizens and in particular that of children." He added that "since there are uncertainties about the effect of exposure of infants to bisphenol A, the Commission considered necessary and appropriate action."

Bisphenol A is an organic molecule used in the manufacture of polycarbonate, which in turn are used to produce plastics, including baby bottles. Small amounts of this substance can pass from a plastic heated to a high temperature containing foods.

The first six months of baby's life are the period that is more exposed to bisphenol A. Which is still in its training course food disposal system, babies can not evacuate.

The prohibition of this substance was established in a directive adopted in January. Since then, the industry has been voluntarily recalling these bottles and it is forbidden to manufacture in the EU since March. In 2010, France and Denmark have adopted national measures to restrict their use.

The Food Standards Agency found that a daily intake of 0.05 milligrams per kilogram of weight is safe and that exposure of all population groups is below this limit. However, concluded that to determine the impact on babies need more research.
