How Often Should You Replace Your Plastic Cutting Boards?

Nearly everyone has a cherished cutting board—the one that stays put, boasts the ideal dimensions, and cleans up effortlessly. However, just like anything else, cutting boards have a limited lifespan. Discover from the specialists when it’s time to renew your plastic cutting boards with Food and Meal.

The Tell-Tale Sign To Replace Your Plastic Cutting Board

According to the U.S. Department of Agriculture (USDA), all cutting boards eventually reach the end of their usable life. When cutting boards become severely worn or develop deep grooves that are hard to clean, it’s time to retire them, advises the agency.

Zahra Mohammad, Ph.D., an expert in food microbiology and safety affiliated with the University of Houston and the American Society for Microbiology, concurs. She led multiple research projects investigating the potential transfer of microorganisms between hands, kitchen utensils, food items, and cutting boards. While these studies are currently undergoing peer review, they revealed a startling finding: a transfer rate exceeding 30% for pathogens like salmonella, E. coli, listeria, and staphylococcus in kitchen settings.

Dr. Mohammad emphasizes, “Over time, cutting boards can accumulate scratches and grooves, making them challenging to clean effectively. This creates an environment where bacteria and mold can thrive, ultimately contaminating your food. Consequently, it’s crucial to replace your cutting boards when you notice that they no longer clean easily.”

In simple terms, when those persistent dark and unsightly cut marks on your plastic cutting board remain even after a thorough cleaning, it’s a clear signal that it’s time to invest in a new one.

Choosing and Using Cutting Boards

While all cutting boards have the potential to host harmful bacteria, plastic boards outshine their wooden counterparts due to their nonporous nature. This nonporous quality makes plastic cutting boards particularly safe for handling raw meat.

For enhanced hygiene, it’s advisable to maintain separate cutting boards designated for various food categories in your kitchen. The USDA recommends using one cutting board exclusively for fresh produce and bread, and another dedicated solely to raw meat, poultry, and seafood. This segregation can effectively prevent cross-contamination, ensuring that bacteria from raw meat doesn’t transfer to foods that don’t require cooking. To help you keep track of their designated purposes, you can opt for different colored cutting boards, such as using a green board for vegetables and a red one for meat.

Cleaning plastic cutting boards is a straightforward process


After each use, it’s crucial to clean your cutting boards thoroughly. Start by washing them with hot, soapy water. Rinse them diligently until the water runs clear, and then allow them to air dry naturally or use paper towels to pat them dry. Plastic cutting boards can also be conveniently cleaned in the dishwasher.

However, if the cutting board was used for handling uncooked fish, meat, or poultry, it’s essential to take additional sanitization steps as recommended by the American Cleaning Institute. Prepare a sanitizing solution by mixing 1 tablespoon of unscented liquid chlorine bleach with every 1 gallon of water. Liberally apply this solution to the cutting board’s surface, allowing it to sit for several minutes. Afterward, rinse the board thoroughly and ensure it’s completely dry.
