Well, for one, they're not. "Apparently" in their post implies that they are, but instead signals that they haven't done any actual research. For instance, hard wood cutting boards are permissible for use in Wisconsin: https://docs.legis.wisconsin.gov/code/admin_code/atcp/055/75_.pdf https://docs.legis.wisconsin.gov/code/admin_code/atcp/055/75... The USDA also recommends wooden cutting boards be used so long as they are properly washed and sanitized before and after use: https://www.fsis.usda.gov/food-safety/safe-food-handling-and-preparation/food-safety-basics/cutting-boards https://www.fsis.usda.gov/food-safety/safe-food-handling-and... The main issues with using wood are 1) that generally you don't want to put them in a dishwasher, 2) it's trickier to track cross-contamination as you might with color-coded boards, and 3) they're much more expensive than plastic.
