I would love to eventually stop using plastic food storage bags all together; however, at this point in my life I feel ok simply reusing them. Good for the planet and the checkbook. Anyway, after the Nalgeen and plastic water bottle #7 scare last year, I began questioning the safety of reusing food storage bags. Were they made for one-time only use? Can they be washed and dried and stored over and over again without leaking nasty, harmful substances like Bisphenol A into our food?
Green America answered this very question for me in their most recent issue of Real Green. According to Real Green, most food storage bags are made from plastic #4, which is considered a “safe” plastic, and washing and reusing such bags should be okay. They do, however, recommend that you a) avoid reusing bags that have held meat or cheese b) avoid putting warm/hot food in plastic c) NEVER microwave food in plastic. Simple enough!
