Kitchenware

The concern: Kitchen items like chopping boards, food storage containers, non-stick cookware, and utensils are in constant contact with your food. Plastic chopping boards shed microparticles when scored by knives. Non-stick coatings can flake and release micro and nanoplastic particles when scratched. Heating food in plastic containers — whether in the microwave or dishwasher — accelerates polymer breakdown and increases microplastic shedding significantly. Even "microwave-safe" plastic containers are only certified not to warp or melt; the label says nothing about microplastic release at those temperatures.

Why it matters: Kitchen contact means microplastics can enter your food directly, and the estimated volumes are substantial. Research in Environmental Science & Technology estimated 7.4 to 50.7 grams of microplastics per person per year from a polyethylene chopping board, and 49.5 grams a year from polypropylene — a modelled annual figure based on assumptions the authors state, not a measured per-use dose. Non-stick pans release an estimated 2.3 million microplastic particles when the coating is damaged. Cooking at high temperatures — frying, roasting, boiling — accelerates shedding from any plastic or non-stick surface in contact with the food. With three meals a day plus snacks, the kitchen is where cumulative daily exposure is highest. Choosing microplastic free kitchenware UK families can rely on reduces one of the most consistent sources of dietary microplastic contamination.

What to look for: Glass, stainless steel, cast iron, and wood are the lowest-concern materials for food contact. Choose glass food storage containers, wooden or wood-composite chopping boards, cast iron or stainless steel cookware, and wooden or stainless steel utensils. For food storage, glass containers with snap-lock lids (stainless steel or silicone-sealed) are ideal for fridge and freezer use. Wooden chopping boards (maple, beech, or bamboo) are self-healing and naturally antimicrobial. For cookware, cast iron and stainless steel are virtually indestructible and improve with age. Avoid plastic spatulas and nylon turners — opt for silicone, wood, or stainless steel alternatives. Regular care extends the life of these items: season cast iron, oil wooden boards, and hand-wash glass containers to keep them in top condition.
