 The plastic cutting board is putting millions of microplastics into your food. A study found that using plastic cutting boards could expose you to up to 79.4 million microplastics per year. The USDA actually recommends using a wooden cutting board for everything including meat, fish, and poultry. But if you can, use a separate wooden board for your produce and bread to protect from cross-contamination. Bamboo, glass, and marble cutting boards are also great alternatives.
