Is it Okay to Cut Chicken on a Wood Cutting Board?

One of the perennial questions that plague both amateur and seasoned cooks alike is whether it’s safe to cut chicken on a wood cutting board. The concern primarily revolves around the risk of cross-contamination and the ability to properly sanitize the board after use. Let’s delve into the facts to shed light on this culinary conundrum.

The Debate

Historically, many have believed that plastic cutting boards are superior to wooden ones for cutting raw poultry due to the porous nature of wood, which could potentially harbor bacteria. However, recent studies have provided surprising insights.

What the Research Says

Research conducted by microbiologists has found that wood cutting boards can actually be safer than plastic ones in some respects. Wood has natural antibacterial properties, and bacteria such as those from raw chicken tend to decrease on wood surfaces over time, whereas they can survive and even multiply on plastic boards.

The research around using wood versus plastic cutting boards, especially concerning the safety of cutting raw chicken, has yielded some surprising and insightful results. One of the seminal studies in this field was conducted by Dr. Dean O. Cliver and his team at the University of California, Davis. Here’s a more detailed look at their findings and other relevant research:

Key Findings from the UC Davis Study

  • Bacteria Absorption: The study found that wood cutting boards absorbed bacteria (like Salmonella, E. coli, and Listeria) into the wood’s fibers. Interestingly, these bacteria did not survive for long, suggesting that the wood’s natural properties might have antimicrobial effects.
  • Recovery of Bacteria: When trying to recover these bacteria from wooden boards after they had been cleaned, researchers found that the bacteria were not recoverable after a short time, meaning they either died or were unable to reproduce. In contrast, bacteria remained on plastic surfaces even after cleaning.
  • Deep Cleaning: The study also showed that even when wooden boards were deeply scored with knives (mimicking heavy use), cleaning them in a standard home dishwasher was effective in killing bacteria lodged in knife grooves. This was a surprising find, as it was initially believed that grooves in wood would harbor bacteria.

Additional Research and Considerations

  • Antimicrobial Properties of Wood: Other studies have supported the notion that wood has natural antimicrobial properties. For instance, certain types of wood, like bamboo, have been found to have natural compounds that can kill bacteria or inhibit their growth.
  • Porosity and Moisture: The porosity of wood is both a blessing and a curse. While it can absorb bacteria away from the surface, improperly maintained wood (i.e., wood that remains damp) can facilitate bacterial growth. However, when properly dried, the lack of moisture makes the environment inhospitable for bacteria.
  • Plastic Board’s Downside: Over time, plastic boards can develop grooves from cutting, which can harbor bacteria. Unlike wood, these grooves may not close up and can be difficult to clean thoroughly, potentially leading to a higher risk of cross-contamination.

The Proper Handling

  • Cleaning: After cutting raw chicken on a wooden cutting board, it’s crucial to clean it immediately. Use hot, soapy water and scrub the board thoroughly to remove any residue. Rinse well.
  • Disinfecting: To disinfect, you can use a solution of bleach and water (1 tablespoon of bleach per gallon of water) or a vinegar solution. Apply it to the board and let it sit for a few minutes before rinsing it off.
  • Drying: Bacteria need moisture to thrive, so ensure your wooden board is completely dry before storing it. Standing it upright can aid in the drying process and prevent warping.

Additional Tips

  • Separate Boards: If possible, use separate cutting boards for raw meats and other foods to avoid cross-contamination.
  • Regular Maintenance: Periodically, you should oil your wooden cutting board with food-grade mineral oil to keep it from drying out and cracking, which can harbor bacteria.

Conclusion

So, is it okay to cut chicken on a wood cutting board? Yes, it can be safe, provided that the board is cleaned and sanitized properly after each use.

The natural properties of wood, combined with proper kitchen hygiene, can make wooden cutting boards a safe option for handling raw chicken. As with any kitchen tool, the key to safety lies in proper maintenance and handling.
