Some Baby Teethers Hold Endocrine Disrupting Chemicals

New findings published in the Journal of Applied Toxicology reveal that two of ten teethers, otherwise known as plastic toys that are used to sooth a teething infant, held endocrine disrupting chemicals that can ease aches and pains in a baby's mouth. However, they can contain added health risks.

Researchers found that one contained parabens, which are normally used as preservatives in cosmetics, while the other contained six so-far unidentified endocrine disruptor's.

The detected substances, including methyl, ethyl and propyl parabens, can act as natural oestrogen in the body, in addition to the effects of androgens like testosterone.

"The good news is that most of the teethers we analyzed did not contain any endocrine disrupting chemicals. However, the presence of parabens in one of the products is striking because these additives are normally not used in plastic toys," said Dr. Martin Wagner, of the Department Aquatic Ecotoxicology at the Goethe University, in a news release.

Furthermore, the EU Commission recently banned two parabens in certain baby cosmetics due to health concerns.

"Our study shows that plastic toys are a source of undesirable chemicals. Manufacturers, regulatory agencies and scientists should investigate the chemical exposure from plastic toys more thoroughly," Wagner concluded, noting the limited benefit at the quality of these products with the higher risk of potential health issues.
