What should food containers not made out of?

Here's a breakdown of materials that are generally NOT recommended for food containers, and why:

Materials to Avoid for Food Containers:

* Polycarbonate (PC): Often found in reusable water bottles and some food storage containers. PC contains Bisphenol A (BPA), which can leach into food, especially when heated. BPA is linked to potential health concerns.

* Melamine: Commonly used in dinnerware. Melamine can release formaldehyde, a known carcinogen, when heated or scratched.

* Styrofoam (Expanded Polystyrene): Can leach styrene, a potential carcinogen, into food, particularly when heated. Also, it's not biodegradable.

* PVC (Polyvinyl Chloride): Often used in cling wrap and some food packaging. PVC can contain phthalates, which are endocrine disruptors.

* Lead: Found in some older ceramicware and painted cookware. Lead is a toxic metal that can accumulate in the body.

* Cadmium: Another toxic metal, sometimes found in older ceramicware. It can leach into food, especially if acidic foods are stored in these containers.

Important Considerations:

* Heat: Avoid using any container, regardless of material, for microwave heating unless it's specifically labeled as microwave-safe.

* Acidic Foods: Some materials are more prone to leaching when exposed to acidic foods (like tomatoes or citrus).

* Reusable vs. Single-use: Reusable containers are generally a better environmental choice, but make sure they're made from safe materials.

Safe Alternatives:

* Glass: Generally considered very safe, inert, and recyclable.

* Stainless Steel: Durable, rust-resistant, and recyclable.

* Silicone: Heat-resistant, flexible, and often BPA-free.

* Bamboo: A natural and renewable material, but make sure it's food-grade and sealed properly.

Before purchasing any food container, always check the label and look for:

* BPA-free: Indicates it's free of bisphenol A.

* Microwave-safe: For use in the microwave.

* Dishwasher-safe: For cleaning in the dishwasher.

* Food-grade: Means the material is safe for food contact.
