CONSUMERS anxious to reduce their exposure to suspect
plastics components won’t find the going easy. Labeling
of plastics ingredients is not required in all cases,
making it hard for consumers to confidently identify all
products containing phthalates or bisphenol A (BPA),
man-made components believed to be harmful to health.
But there are some steps people can take to lower
possible risk, toxicology experts say. Some blame
plastics for increased rates of cancer, asthma,
neurological disorders and infertility.
To
reduce contact with possibly harmful plastics components
in general:
n Avoid
placing hot food or liquids in plastic containers. Use
glass, ceramic or stainless-steel containers instead.
Heating plastics to high temperatures promotes the
leaching of chemicals out of containers and into the
food or liquid they hold.
Freezing
liquids in plastic bottles, incidentally, poses no such
risk. Contrary to recent online reports that claimed
freezing water releases carcinogenic materials into
water, freezing actually retards the release of
chemicals.
§
When
heating food in a microwave oven, use only cookware that
is labeled “microwave safe.”
§
Remove
food from plastic wrapping before thawing or reheating
in a microwave.
§
Buy
products in cardboard cartons instead of plastic
containers.
§
Check
recycling codes on the bottom of store packages for
clues about plastics components you may want to avoid:
Recycling code 3 may indicate the product contains a
type of phthalate known as DEHA. Recycling code 7 may
mean the product contains BPA.
To avoid
exposure to BPA:
§
Look for
toys, baby bottles and containers claiming to be BPA-free.
There’s been a recent explosion of such products, many
of them priced higher than standard products. There is
also a growing industry of third-party certifiers to
test such claims. Gerber’s Clearview Bottles are BPA-free;
a three-pack costs about $3 at Target.
§
Reduce
your use of canned food; eat fresh or frozen foods
instead. Bisphenol A has been found in the lining of
canned food tins.
§
Reduce
your use of polycarbonate and polyvinyl chloride (PVC)
plastics, both of which contain BPA. Choose alternatives
such as polyethylene plastic (also labeled PETE) and
containers marked with recycling code 1, 2 (HDPE) and 4
(LDPE). Polypropylene (recycling code 5, or PP) is also
considered a safe choice.
§
If you
use hard polycarbonate plastics (Nalgene bottles, baby
bottles, sippy cups), do not heat them or use them for
warm or hot liquids.
§
Do not
wash polycarbonate plastic containers in the dishwasher
with harsh detergents.
To
minimize exposure to phthalates:
§
Look for
phthalate-free toys or those approved by the European
Union (EU).
§
Do not
microwave or heat plastic wraps. Those that are labeled
microwave-safe should be placed loosely over containers.
Make sure they do not touch the food.
§
Choose
personal-care products that do not contain synthetic
fragrance. While the Food and Drug Administration (FDA)
requires the listing of ingredients on cosmetic products
sold in retail stores, it does not require the listing
of individual fragrance ingredients.
§
Check
the labels of nail polish. The FDA requires that
phthalates be listed unless they are a fragrance
ingredient. Phthalates are used in some nail polishes to
reduce cracking.
