Yes, freezer bags can be reused, provided they are properly cleaned beforehand.
The Key to Reusing Freezer Bags
Reusing plastic freezer bags is possible and can be an eco-friendly choice, but cleanliness is paramount for food safety. According to Carla L. Schwan, Ph. D., assistant professor and extension food safety specialist director at the National Center for Home Food Preservation, it can be safe to reuse a plastic bag as long as it is washed properly first.
This highlights the critical step required before a bag that has contained food is used again.
Ensuring Food Safety
Proper washing is essential to remove food residue and prevent the growth of bacteria that could contaminate new food placed in the bag. Reusing a bag that hasn't been thoroughly cleaned, especially after holding raw meats or other perishable items, poses a health risk.
When to Reuse and When to Discard
While many bags can be washed and reused, some situations warrant discarding the bag to ensure safety:
- Reuse is Generally Okay:
- Bags that held clean, dry items like bread, crackers, or produce that wasn't dirty.
- Bags used for freezing items like baked goods or vegetables after they've been cleaned.
- Avoid Reusing (Discard Instead):
- Bags that contained raw meat, poultry, or seafood juices.
- Bags that held oily or greasy foods that are difficult to clean thoroughly.
- Bags that are ripped, torn, or show signs of wear.
- Bags that have held strong odors that won't wash away.
Tips for Washing Freezer Bags
To safely reuse a freezer bag, follow these simple steps:
- Empty all contents and turn the bag inside out.
- Rinse the bag thoroughly with cool water to remove any remaining food particles.
- Wash the bag with warm, soapy water, paying close attention to corners and the zipper seal. A bottle brush can be helpful.
- Rinse again with clean water.
- Allow the bag to air dry completely before storing or reusing. Hanging them upside down helps water drain.
- Inspect the bag before reuse to ensure it is clean, dry, and undamaged.
By taking the time to wash them correctly, you can give your freezer bags a second life.
