| Re: What containers are unsafe to store food?
Saran plastic wrap is made with a PCB plasticizer, which is an endocrine disruptor. It's generally a better idea to buy a plastic wrap made from polyethylene, such as Glad brand wrap. There are also plenty of generic plastic wraps made from polyethylene. This is mainly an environmental issue more than a food safety issue; there's a lot of waste PCBs that end up getting dumped into the environment when Saran wrap is manufactured, while the manufacturing process for polyethylene is relatively benign.
As for personal health risks, the only time you really need to worry is if you heat food while it's in contact with the plastic wrap. Sometimes this happens when people microwave food without taking the plastic cover off. Even then, the danger is pretty negligible. Simply storing food under Saran wrap isn't anything to be concerned about.
