Bisphenol-A (BPA) has been temporarily banned in Denmark from food packaging intended for children. The plasticizing additive, widely used in the linings of food and beverage cans as well as in polycarbonate containers such as sippy cups, has been linked by studies to a variety of cancers and other disorders. Although most countries, including the U.S., have declined to ban the substance outright, Danish authorities instituted their ban on the grounds that the substance could prove harmful to the brain development of children up to age 3. The ban goes into effect July 1 and covers packaging for baby food as well as baby bottles and cups.
