I once went to Dr Little the allergy specialist and he was always cautioning people about buying food wrapped in plastic. It is hard to know what is or isn't safe where plastics are concerned. I find this list helpful.
You can tell which plastics to avoid by checking the numbers printed on the bottom of the containers.
Here are the ones you should stop using:
#3 — Polyvinyl chloride (often abbreviated PVC or V): PVC is found in bottles that contain cooking oils, cling wrap, the clear wrap around deli meats and cheeses, plumbing pipes, shower curtains, and toys. This type of plastic contains hormone-disrupting phthalates and cancer-causing dioxins that can leach out when the plastic comes into contact with heat, food, water, air, or our bodies.
JILLIAN'S TIP OF THE DAY
Look for #7 PLA
There's one type of #7 plastic that's okay. It's called polylactide plastic, often labeled PLA. PLA is made from corn, potatoes, sugar, or other plant-based starch, and it's fully compostable! Check the code on the bottom of every container you have — always avoid PC, but PLA is fine.
