Science shows that plastics are the most chemically complex food-contact materials, with nearly 2,000 different migrating substances detected. Migration intensifies with heat, fat content, acidity, and long contact times. Heating plastic containers can release dozens of chemicals and millions of microplastic particles per liter into food.
This is MEDIUM PRIORITY because food storage involves prolonged contact between food and containers, though often at lower temperatures than cooking.
Laurel recommends glass for food storage. High-quality stainless steel and platinum-cured silicone are also safe alternatives.
Laurel avoids products where plastic is in prolonged contact with food, especially if the food is hot, fatty, or acidic. We also avoid anything with a nonstick coating.
Tip: Never microwave food in plastic containers -- transfer to glass first. This one change can dramatically reduce your exposure.
