Why This Happens: The Real Cause
Wooden cutting boards can become breeding grounds for bacteria due to their porous nature. The main reasons are:
- Porous Surface: Absorbs moisture, leading to bacterial growth.
- Knife Marks: Create grooves that trap food particles.
- Improper Drying: Moisture remains, fostering bacteria.
- Lack of Regular Cleaning: Allows bacteria to multiply undisturbed.
- Cross-Contamination: Using the board for multiple food types without cleaning.
