Recent studies suggest that plastic cutting boards, although the most common choice in kitchens, may be an invisible source of contamination. When knives are used on these boards, small plastic fragments can break off and transfer to food without being noticed. These microscopic plastic particles contribute to food contamination, posing a health risk over time.
A study published in October 2022 in the International Journal of Environmental Research found that meat and fish in the Middle East contained plastic particles due to the use of these boards. Another study in May 2023 confirmed that polypropylene cutting boards produce larger plastic pollutants compared to polyethylene, with individuals potentially exposed to millions of tiny plastic particles annually.
Despite these concerns, wooden cutting boards remain a popular alternative for many. However, there are concerns about bacteria accumulating in deep grooves on their surface. Regular cleaning with soap and warm water, along with traditional methods like using a baking soda and salt solution, can help maintain their cleanliness and effectiveness.
Wooden boards are not only healthier but also help preserve the sharpness of knives for a longer time. Though they come at a higher cost, they last longer than plastic and do not require frequent replacements. To ensure food safety, it is recommended to designate separate boards for different types of food: one for fruits and vegetables and another for meat and seafood.
Ultimately, whether you choose wooden or plastic boards, it is essential to replace them immediately if any signs of damage appear to ensure food safety and overall health.
