The evils of fast food are seemingly endless: they are hazards to both our health andto the environment, and who knows what the consequences of all the preservativesare. But now, turns out the packaging also leaches its own worrisome problems directly into the food wrapped inside them.
A new study has found that perfluoroalkyls, synthetic chemicals that repel oil and are used on paper packaging like food wrappers and popcorn bags to prevent grease from leaking through them, can migrate directly into food—and then into human blood, where these chemicals have already been found.
ENS reports that in addition to food packaging, perfluoroalkyls are used in "surface protection products such as carpet and clothing treatments and coating for paper and cardboard packaging," but the Agency for Toxic Substances & Disease Registry, a branch of the CDC, shows that perfluoroalkyls are also used in "fire-fighting foams."
There are different types of perfluoroalkyls and the agency does not specify which is used for this purpose, but if it's even a different acid in the same category, how comforting is that?
Perfluoroalkyls are known to stay in the body for years—according to the Agency for Toxic Substances, "It takes approximately 4 years for the level in the body to go down by half, even if no more is taken in." The effects can include changes in sex hormones and cholesterol levels.

Very alarming to say the least. I wonder why such migration/contamination was not be detected prior to commercialization
Please note that not all greaseproof is coated with PFC. Our 'natural' greaseproof has no chemical coating, costs a little more than the nasty stuff but looks, feels and is a lot better. Of course being natural its recyclable & biodegradable. see www.ecoluxe.co.uk
