Baby teethers in US contain bisphenol-A

Researchers in the United States who tested five dozen baby teethers found that although most of them were labelled BPA-free or non-toxic, all of them contained BPA.

A chemical that's banned from baby bottles and children's drinking cups is still widely used in baby teethers, a new study finds.

Endocrine disruptors

Researchers in the United States who tested five dozen baby teethers found all of them contained bisphenol-A (BPA) and other endocrine-disrupting chemicals.

Studies in animals have shown that endocrine disruptors interfere with hormones and cause developmental, reproductive and neurological harm, according to the study authors.

Although most of the teethers were labelled BPA-free or non-toxic, all of them contained BPA, the study found. BPA is banned from children's drinking utensils in the United States and much of Europe.

The teethers also contained a range of parabens and the antimicrobial agents triclosan and triclocarban, which are also endocrine disruptors, the researchers said.

Potentially harmful chemicals

"The findings could be used to develop appropriate policies to protect infants from exposure to potentially toxic chemicals found in teethers," said study author Kurunthachalam Kannan and colleagues from the New York. State Department of Health's Wadsworth Centre

Baby teethers are used to soothe babies' gums when their teeth start coming in, at around 3 to 7 months of age.

Because babies suck on teethers, the presence of potentially harmful chemicals on the surface is concerning, the researchers said. The study authors said this is especially true since they found that BPA and other chemicals leached out of the teethers into water.

The 59 teethers analysed were purchased online in the United States and tested for 26 potential endocrine-disrupting chemicals, the researchers said.

The results were published in the journal Environmental Science & Technology.
