I am more and more terrified of plastics. There is so much of it out there and it's really confusing when it comes to choosing what's best for your family.
Every single time I hand my daughter a plastic sippy cup, plate or utensil I think twice. There are special plastics markings which we should look for when looking for safety but sadly there are more unmarked plastics out there than not.
Bisphenol-A (BPA) has received a lot of bad rep since 2008 and deservedly so. In Oct 2010 Canada was the first country to declare BPA toxic and ban its use in food & drink containers such as baby bottles. Today I found out that the EU has also banned the use of BPA in baby bottles starting in March 2011, and banned for import and sale as of June 2011.
According to Wikipedia, BPA is a chemical that mimics the action of the human hormone estrogen.
BPA has been found to stimulate prostate cancer cells and causes breast tissue changes in mice that resemble early stages of breast cancer in both mice and humans. One study found an association between ovarian dysfunction and higher levels of BPA in urine.
BPA is primarily used to make polycarbonate plastic food and beverage containers, plastic food wrap, and epoxy resins that are used to line metal cans for food, such as cans of soup. Polycarbonate plastic food and beverage containers that contain BPA will be labeled recycling #7.
What we need to know (taken from eHow):
PETE, Labeled 1, Polyethylene Terephthalate - Common in drink containers (soda, water, etc.) food jars and cosmetic holders. This material is not designed for repeated use due to leaching and bacteria growth.
HDPE, Labeled 2, High density Polyethylene - This is common in milk and juice containers as well as grocery and shopping bags. From what we know, it appears to be safe.
PVC, Labeled 3, Polyvinyl Chloride - This is found in vinyl shower curtains, baby mattresses, window frames, meat wrap just to name a few. PVC is known as the Poison Plastic because of the dangerous toxins it contains.
LDPE, Labeled 4, Low density polyethylene - Found in sturdy trash bags, bread bags, squeezable bottles and food wrap. This one also appears to be safe.
PP, Labeled 5, Polypropylene - Common in medicine bottle, cereal bags, straws, chip and snack bags, and food storage containers. Also in children's sippy cups and bottles. This one also appears to be safe.
PS, Labeled 6, Polystyrene - Used in CD/tape cassettes, plastic cutlery, egg cartons, and take out containers. Avoid this one as it is a possible carcinogen and hormone disruptor. It may leach styrene.
The most confusing is the one labeled 7, which is "other" OR "PC" which is toxic Polycarbonate. This is sadly found in baby bottles, baby food containers, formula containers, pacifiers, and car parts. It is better to be safe than sorry and avoid this one. The concern is from leaching of Bisphenol A which appears to cause chromosomal damage.
- I've done some further research on label #7 and have found that there are some bottles marked with number 7, and promoted as BPA free, underneath it's written Tritan, BPA Free. However, although it is BPA free it doesn't actually mean that it's safe. This is because the ingredients that make up Tritan have been kept secret. So we have no way of knowing whether its safe. It could contain some other dangerous chemical, or not.... we just don't know.
- I should state that there are some number 7 plastics which are safe but do not belong to any other category so are sadly lumped here. Such as Biobased plastics which are basically plastics made of plants instead of toxic chemicals. But those plastics should be marked as such.
Now the scary point is that when heated, even the safe plastics emit BPA. So basically, we should not microwave food in plastic containers, and we should really avoid putting them in the dishwasher as well. We should not put hot foods in plastic containers for storage but wait until cooled to do so. The more the plastics are used, scratched and worn out, the more chances there are of BPA leaching out.
I've basically made a decision to completely reduce the use plastics with Emma and all my future children. I'm switching to stainless steel as soon as I can get my hands on a bottle. There are even stainless steel baby bottles. I've actually decided to go so far and import stainless steel baby bottles, sippy cups and sports bottles to Cyprus. So if anyone in Cyprus wants one, please let me know!

We appreciate comments! As a thanks, this is a do-follow blog.
