The meal prep trend encourages home cooks to get smart about how they store their ingredients and leftovers, which requires a healthy supply of food storage containers. Many of us reuse the same plastic, glass, or stainless steel containers over and over again for months or even years. But if the priority is fresh and flavorful food that's also safe to eat, should we be replacing our containers more regularly? According to food safety experts, food scientists, and home cleaning and organization pros, the answer is "yes".

Glass and Stainless Steel: Built to Last

Glass containers, ceramic, or stainless steel containers will give you the most longevity. If you're in the market for reusable food storage containers that are strong enough to last a lifetime, then glass, ceramic, and stainless steel are the way to go. "Glass is the most durable and has the greatest longevity, and it's 100% recyclable," explains Nicole Gabai, a professional organizer.

Plastic: Replace Every 6-12 Months

Plastic storage containers can last at least a year with proper maintenance. However, "plastic food storage containers should be replaced every six months to one year, depending on usage and wear and tear," explains Dragomir Markovic, food scientist. Over time, plastic containers can become scratched, stained, or damaged, and that starts to pose a food safety risk.

Signs It's Time to Replace

· 

Scratches or punctures that can harbor bacteria

· 

· 

Stains that won't wash out

· 

· 

Warping or misshapen containers

· 

· 

Lids that no longer seal properly

· 

· 

Cloudiness indicating surface degradation

When to Replace Glass and Stainless Steel

Glass containers are more durable and reliable, but they can scratch or crack. Stainless steel containers are "just as effective, but way stronger". Replace glass if chipped or cracked. Replace stainless steel if significantly dented or if seals fail.
