Nutrition experts have raised concerns about microwaving food in plastic containers, warning that it could expose consumers to harmful chemicals that may increase the risk of cancer.
These chemicals, such as bisphenol A (BPA) and phthalates, can leach into food when heated, posing health risks including endocrine disruption, fertility issues, and metabolic disorders.
The experts emphasized that while some plastic containers are labeled as “microwave-safe,” this designation only refers to their ability to withstand heat, not their safety for human health.
How to safely store and reheat food
- Let food cool before adding it to a plastic container, then put it in the fridge immediately. Avoid plastics that are visibly damaged or stained or have a bad smell.
- Use glass, ceramic and plastic containers and plastic wrap that are labelled as microwave safe. Always follow the instructions on the label when you use microwave-safe containers to heat food.
- Never heat or store food in plastic containers that were not intended for food. Single-use containers, like margarine tubs, tend to warp or melt in the microwave. This may allow more of the substances in the plastic to leach into the food.
