The following is an addendum to Earth Day Remembers North Pacific Trash Gyre. I was going to tack this onto the same post, but it’s getting too long. Please observe the following cautions when buying your food in plastic containers. Common plastic containers and plastic lined metal containers may be leeching toxic chemicals into your food even as it sits on supermarket store shelves.
The toxicity studies are still on going. The common question is, “why would THEY sell food in containers that are not safe?” THEY, meaning the big, industrialized food producers, are interested in maximizing their profit by using the cheapest containers possible. When greed comes in first, Your Safety comes in second. Please observe the following precautions:

What Plastics Do to Your Body
Scientists are mostly worried about bisphenol-A or BPA. Its an endocrine disruptor and in numerous animal studies its been linked to cancer, infertility, obesity and early puberty, says Anila Jacob, M.D., M.P.H., a senior scientist at the Environmental Working Group, a non-profit research and advocacy organization in Washington, D.C. The CDC has found this chemical in 93 percent of people they have tested, she says.
BPA is a chemical used to make polycarbonate plastic or items marked with the number 7 on the bottom. Some plastic dishes, cups, reusable water bottles and baby bottles are made out of polycarbonate. Heating foods in polycarbonate plastic increases the amount of BPA that leaches into food, Jacob says. Frances Beinecke, president of the National Resources Defense Council, an environmental action group, worries about BPAs possible role in breast cancer. Beinecke, a breast cancer survivor, says BPA is a synthetic form of estrogen, and doctors know estrogen feeds breast cancer.
It ramps up cell division in pre-cancerous cells and it can prompt tumors to metastasize, she says. In animal studies, BPA has been found to cause the early onset of puberty and stimulate mammary gland development in females. The estrogen-like properties in BPA are so strong that even when male rodents were exposed to it, they had an increased risk of mammary tumors. The studies done to date have all been on animals, Jacob says, because its difficult to study in humans as we have already been exposed via multiple routes. We think the animal data is convincing enough that it warrants concern, Jacob says.
BPA also is used to line the inside of metal food and soda cans and can leach from the can liner into the food. Acidic foods like tomato sauces and soda absorb more BPA. Other plastic containerslike those made with polyvinyl chloride or PVC and marked with the number 3 concern scientists for health and environmental reasons. PVC contains phthalates, softeners need to make the plastic bend and they have been found to interfere with hormonal development. The production of and burning of PVC plastic releases dioxin, a known carcinogen, into the atmosphere.
All food plastic wraps used to be made with PVC, but many large name brands have quit using PVC. However, the cling wrap used for commercial purposes, such as the meat department of your grocery store, often contain phthalates. Gina Solomon, M.D., M.P.H., a senior scientist with the NRDC, suggests checking the date when you buy food wrapped in cling wrap. Buying something recently wrapped is your safest bet, she says.
For its part, the FDA agrees that substances used to make plastics can leach into food. But the agency says it has studied them and found the levels to be well within the margin of safety based on information available to the agency. (so says the special interest agency that approves prescription drugs that have caused innumerable deaths in once healthy people including Gardasil.)
“Safer” Plastics
#1 PETE or PET (polyethylene terephthalate)used for most clear beverage bottles, such as 2-liter soda, cooking oil bottles and peanut butter jars. One of the most commonly recycled plastics on the planet.#2 HDPE (high-density polyethylene)used to make most milk jugs.
#4 LDPE (low-density polyethylene)used in food storage bags, some cling wraps and some squeeze bottles.
#5 PP (polypropylene)used in opaque, hard containers, including some baby bottles and some cups and bowls. Drinking straws and yogurt containers are sometimes made with this.
Avoid These
#3 PVC (polyvinyl chloride)used in commercial plastic wraps and salad dressing bottles.
#6 PS (polystyrene)used in Styrofoam cups, meat trays and clam-shell-type containers.
#7 Other (these contain any plastic other than those used in #1-6. Most are polycarbonate which contain BPA)used in some water bottles, Nalgene water bottles, some baby bottles, and some metal can linings.
Easy Tips
Using plastic water bottles? Go for a metal or stainless steel container instead.
Using a plastic spatula? Try using a metal spatula or wooden spoon instead.
Using Tupperware? Try pyrex glass containers that go straight from the fridge to the oven. When you use a plastic container in a microwave oven, you are guaranteed to each plastic with your food. Buying ready-to-drink juices? Frozen concentrate stores longer and is typically packaged in paper.
Using plastic cutting boards? How about a bamboo cutting board?
Using a plastic lunch box? A stainless steel laptop lunchbox provides a sturdy, elegant alternative. Or how about a clothe bag or just reuse a paper bag you got from the supermarket?
