Phthalates Are Out Of Infants’ Toys But A Heavy Dose Is Still In Their Food

Posted:  Tuesday, July 15, 2014

Remember the great phthalate scare of 2008? Congress, in a rare bilateral response to an uproar from parents and health experts that children’s toys made abroad were laced with chemicals that could harm kid’s reproductive systems, banned the toxins so infants would no longer ingest them by mouthing the plastic objects. And then phthalates (pronounced thal-eights) pretty much faded from public view. But a new study shows that an infant with a typical diet is still consuming twice as much of the chemicals as the Environmental Protection Agency considers safe.

Phthalates, a family of chemicals, have been used for decades to make plastic more pliable and cosmetics smoother. Phthalates are not chemically bound to the plastics they're added to, they're continuously released into the air or food or liquid.

Meats in particular and high fat dairy products such as whole milk and cream, cooking oils and fats such as margarine all contain high levels of the chemicals, according to the research. As a result, infants and toddlers who consume solid food are still taking in too much of them, said one of the researchers, Sheela Sathyanarayana, an associate professor of paediatrics at the University Of Washington School Of Medicine.

Sathyanarayana and a team of researchers measured phthalate concentrations in food in the United States and abroad, then created models for four types of diet: one high in fruits and vegetables, one high in meat and dairy, a balanced diet based on government guidelines and a typical American diet. As expected, the fruit and vegetable diet did not expose its consumers to excessive levels of phthalates, and the one high in meat and dairy was unsafe for infants and adolescents. The typical U.S. diet was safe for adults, but the researchers were surprised when they determined that it far surpassed the limit of 20 micrograms of phthalates per kilogram of body weight per day that the EPA has set as a safe level.

The study did not look at how the chemicals came to be highly concentrated in certain foods, but Sathyanarayana said poultry, for example, may be contaminated by packaging and chicken feed; milk may pick up phthalates from plastic tubes that transports it from cow to container. Fresh fruits and vegetables, in contrast, undergo the least amount of processing and contain lower levels of the chemicals.

The good news is that there steps, parents can take to minimize children’s exposure to phthalates. Tips from the researchers include:

• Buy low fat dairy products such as skim milk and low fat cheeses.
• Buy fresh or frozen fruits and vegetables. Avoid processed foods.
• Minimize the use of personal care products that contain phthalates.
• Use glass, stainless steel, ceramic or wood to hold and store foods instead of plastics.
• Do not use hard, polycarbonate plastics to hold hot liquids.
• Minimize handling of receipts, which contain chemicals.
• Take shoes off at the front door to avoid tracking in dust that may contain these chemicals.
• Keep carpets and window sills clean. Vacuum and wet dust frequently to minimize dust that may contain chemicals.
