Is plastic cookware shoving extra chemicals into food when you cook with it?
Yes. New chemical screening finds dozens of extra compounds in food after plastic-tool cooking.
What's actually in it
Plastic kitchen tools and food-contact plastics are made from a base resin plus dozens of helper chemicals: plasticizers, antioxidants, UV stabilizers, colorants, and lubricants. None of these are bonded tightly to the plastic. Heat, fat, and acid pull them out into the food.
Plastic spatulas dragged across hot pans are some of the worst offenders, especially black plastic ones.
What the research says
A 2026 study in Food Chem ran a non-targeted screen of food after cooking with various plastic-contact materials. The team found dozens of compounds moving from the plastic into the food during normal stovetop and oven temperatures. Many were industrial additives that aren't on any safety list because nobody knew to look for them.
The pattern was worst for hot, oily dishes.
Cook with wooden, bamboo, or stainless steel utensils. Skip black plastic spatulas, which are often made from recycled electronic waste. Use glass or ceramic for storage and reheat in glass.
