Is it safe to use a plastic colander for draining pasta?
Based on 1 peer-reviewed studykitchen
Verdict: Avoid
No. Boiling pasta water rushing through plastic shreds particles into every serving.
What's actually in it
Pasta drains at around 100°C. A plastic colander hits that hot water at full pressure every time you drain. Turbulence plus heat is much worse for particle release than either alone.
What the research says
A 2025 study in J Agric Food Chem showed polypropylene releases billions of nanoplastics in hot water. Moving water accelerates the process.
Swap to a stainless steel colander. They cost about the same as plastic and last decades.
