Foods You Should Avoid Storing in Plastic Containers

Plastic containers are a kitchen staple due to their convenience, but not all foods are safe to store in them. Certain items can react with plastic, absorb harmful chemicals, or spoil faster, affecting taste and safety. Experts recommend avoiding storing specific foods in plastic to prevent contamination and preserve freshness.

1. Hot Meals

Placing piping-hot food in plastic containers can warp the material, increase chemical leaching, and trap steam, encouraging bacterial growth. To maintain flavour and health safety, allow leftovers to cool slightly before transferring them to glass or stainless-steel containers.

2. Raw Meat and Seafood

Raw proteins such as meat, poultry, and seafood can carry harmful bacteria. Plastic containers can trap moisture, accelerating bacterial growth and cross-contamination. Storing these foods in glass containers or their original packaging on a drip tray is safer.

3. Acidic Fruits

Acidic foods like tomatoes, citrus fruits, and berries may react with plastic, potentially releasing chemicals and altering taste. For long-lasting freshness, opt for glass or ceramic containers with lids.

4. Fermented Foods

Fermented items—kimchi, pickles, or carbonated drinks—release gas over time. Sealed plastic containers can bulge, spill, or deform. Use glass jars or ceramic containers instead.

5. Oily or Fatty Foods

Cheese, butter, nut butters, and oily sauces can cause chemical leaching when stored in plastic. Glass containers provide a safer, non-reactive alternative.

Safe Storage Tips

Switching to glass, stainless steel, or ceramic containers reduces chemical risks and maintains food quality. Silicone lids and wraps are also good for short-term storage. Always let hot foods cool before sealing and avoid storing acidic or oily foods in plastic for prolonged periods.
