Plastic container safety gets worse every time you do the responsible thing. Every wash. Every microwave cycle. Every time you rinse it out and put it back in the cupboard because it still looks fine.

There is a man with multiple houses who reuses his Ziploc bags to save money. He rinses them and dries them and uses them again. A microbiologist just explained that PVC bags leach more plasticizers with every single reuse, and that the scratches building up inside your containers are not just wear and tear. They are where the bacteria live. The symbol that says microwave safe means the container survives short heat. Nobody prints what happens to the food inside it.

The number is on the bottom of every container you own right now. It is inside the recycling symbol. You have probably never looked at it. That changes today.
