Not sure if someone posted it elsewhere but I only saw this today - issued back in October by Kidsafe...

Kids foam mats declared safe in Australia by the ACCC

Kidsafe Victoria welcomes the release of test results detailing the safety levels of the chemical formamide in ethylene vinyl acetate (EVA) foam mats.

The tests were commissioned by the ACCC, Queensland office of Fair Trading and Consumer Affairs Victoria when Kidsafe reported the issue in February 2011. Concerns were raised after the products were banned in parts of Europe.

The ACCC analysed the findings from 16 EVA products purchased in Australia and reported that:

•half of the products tested released no measurable amount of formamide,
•where formamide was present in the products, the amounts released were very small and;
•the potential exposure to children was calculated and determined to be acceptable levels when compared to the internationally recognised lowest-observable-adverse-effect-level (LOAEL) cited in Environment/Health Canada’s Screening Assessment.
The ACCC stated that the foam play mats available in Australia do not pose any health risks to children and are safe to be used for their intended purpose.
