Are Plastic Cutting Boards Safe?

Yes. Plastic cutting boards made from food-grade materials (such as polypropylene or HDPE) are safe for everyday kitchen use. They are non-porous, easy to clean in the dishwasher, and more hygienic than wood in certain cases. However, once they develop deep knife grooves, bacteria can hide in the cuts. To stay safe, replace boards when heavily worn, wash thoroughly after each use, and use separate boards for meat, seafood, and vegetables.
