Plastic and Food - Handy Tips

We've all read about the risk of microwaving food in plastic containers. I've never really done that, preferring glass containers for the microwave. But I do have a couple of containers in which, admittedly, I have 'nuked' food. It's just easier to go from fridge to micro in the same dish.

Today I was reading my latest Green Living email, the Care2 newsletter about healthy living ideas, and found an article about food and plastic. Not good news, my friends. But a lot of really helpful tips that I just have to share:

Many of these tips don’t exclude the use of plastic, but rather offer the safest options.

1. Know your plastics. Plastic items are marked with a resin identification coding system (the number surrounded by arrows), which stand for:
1 - polyethyelene terephthalate (PETE)
2 - high-density polyethylene (HDPE)
3 - vinyl, polyvinyl chloride (PVC)
4 - low-density polyethylene (LDPE)
5 - polypropylene (PP)
6 - polystyrene (PS)
7 - other (includes polycarbonate, acrylic, polylactic acid, fiberglass)

2. When you need to use plastic, these are the safer choices to use with food: 1, 2, 4 and 5.

3. Learn to recognize, and then avoid, polycarbonate (number 7) for food usage. Polycarbonate plastics are hard and clear. Common items made from this BPA-containing plastic are food storage containers, baby bottles, water bottles, bowls and tableware. (And the lining inside food and drink cans, by the way.)

4. If you don’t get rid of all of your plastic, at least retire old plastic containers, especially those that are heavily worn or scratched. Older plastics tend to leach increasing amounts of toxins as they age. Use them to organize and store non-food items.

5. Be careful of serving and storing hot foods or foods made with fats or oils in plastic containers. These foods more readily facilitate the transfer of plastic toxins.

6. Never microwave foods in plastic containers. “Microwave safe” means the container won’t melt or warp, but doesn’t mean it won’t leach. Heating plastics increases the potential for leaching of chemicals into your food.

7. Never microwave food in yogurt tubs, take-out bowls, or other one-time use containers. These containers can warp or melt, possibly causing harmful chemicals to migrate into the food.

8. Avoid using plastic sandwich bags or plastic wrap products.

9. If you must use plastic wrap, make sure it is a brand free of both BPA and PVC. Ziploc, Glad and Saran are promoted as being free of BPA and PVC—but remember that these plastics live for 1,000 years…in our landfills.

10. Avoid deli-wrap and similar generic packaging since you can’t ascertain the plastic type used. When sliced cheese and meats are sold in plastic bags and/or plastic deli wrap, transfer them as soon as possible to unbleached wax paper or a safe container.

11. Remember that if you are pregnant or nursing, BPA chemicals are passed through your bloodstream directly to your baby.

12. Instead of mixing petroleum (i.e. plastic) with your food, use inert alternatives such as glass and ceramic rather than plastic food storage containers. Reusing jars is a win-win—and you can often find glass storage containers at flea markets and thrift shops. Or simply store food in bowls covered with a plate.

I'm going to go check all of my bowls, storage containers, and that gallon-size pitcher that we keep in the fridge for tea. Wish me luck - I have a feeling I'm in for some serious surprises.
