In a startling revelation that may make you rethink your kitchen habits, experts have found that cutting boards can harbour more germs than a toilet seat. A recent inquiry into the cleanliness of everyday items placed these ubiquitous kitchen tools among the dirtiest household surfaces, sharing the dubious honour with sponges and water bottles. With this in mind, understanding how to properly clean and maintain your cutting board is crucial for ensuring food safety and hygiene.
The Germ Factor: What You Need to Know
While it might sound alarming, it’s important to remember that many items in our homes can be more contaminated than toilet seats, which we routinely disinfect. This is not a reason to panic but rather an invitation to pay closer attention to the cutting board that has just assisted you in slicing zucchini or carving a roast. Proper cleaning methods are essential to avoid unsightly stains, unpleasant odours, and harmful bacteria like salmonella and E. coli.
Dr. Keith R. Schneider, a food safety professor at the University of Florida, reassures us that “washing with soap and water remains an excellent option for most cleaning scenarios.” Let’s delve into the best practices for keeping your cutting board clean and safe.
Best Practices for Cleaning Cutting Boards
Handwashing vs. Dishwasher
When it comes to cleaning your cutting boards, the method largely depends on the material. Most plastic, glass, composite, or stainless steel boards can be tossed in the dishwasher, benefiting from the high temperatures that aid in sanitisation. However, wooden boards require more delicate treatment—handwashing is essential to avoid warping and cracking.
Food writer Marian Bull recommends using gentle, compostable sponges, such as those from Blueland, to protect your wooden surfaces while cleaning. After washing, applying food-grade mineral oil can help keep your board in top condition, preventing moisture absorption and extending its life.
Tackling Bacterial Growth
To prevent bacteria from taking residence on your cutting board, it’s vital to dry it thoroughly after washing. After rinsing off soap, use a cloth or paper towel to absorb excess moisture. Storing a damp board can create a breeding ground for bacteria. Instead, position it upright against a wall or another object, allowing for ample airflow until it is completely dry.
The Role of Antibacterial Products
Fortunately, you typically don’t need to resort to antibacterial soaps for standard cleaning. Regular dish soaps, such as Dawn or Palmolive, combined with warm water, are often sufficient. Dr. Schneider notes that antibacterial soaps provide little added benefit over standard varieties—what you really need is a bit of elbow grease.
When to Sanitize
In situations where you’ve been cutting raw meat—known to carry harmful pathogens—sanitising your cutting board becomes imperative. If your board is dishwasher-safe, a cycle will achieve this, but for hand sanitisation, a simple bleach solution will suffice. Mix one tablespoon of unscented household bleach with a quart of water
