Is it safe to use a plastic cooking spoon in a hot pan?
No. Heat pulls additives and microplastic particles out of nylon or polypropylene utensils into your food.
What's actually in it
Plastic cooking spoons are usually nylon or polypropylene. They're rated for high temperature (typically up to 220°C), but ratings refer to melting, not chemical release. Heat softens plastic and speeds up migration of additives: antioxidants, lubricants, and residual monomers.
Black nylon spoons have an extra problem: they often contain recycled electronics plastic with traces of brominated flame retardants.
What the research says
A 2025 study in J Agric Food Chem showed plastic containers release billions of nanoplastic particles in hot conditions. The same physics applies to plastic utensils stirring a hot pot. A 2025 screening study found flame retardants widely present in consumer goods.
Use stainless steel, wood, or bamboo utensils for cooking. Keep plastic utensils for cold foods only.
