Plastic food containers are part of everyday life in many homes.
People use them to store leftovers. They use them to heat meals. They often trust them without a second thought. This routine habit can turn into a problem when the containers are damaged or used the wrong way. Food safety experts now want people to pay closer attention to what they use in their kitchens.
Look at the Labels
Merja Virtanen works as a specialist at the Finnish Food Authority. She recently spoke to the newspaper Iltalehti about the risks linked to certain plastic food containers. Her message was simple. Damaged or misused containers can affect your health over time.
Many people do not notice when a plastic container starts to wear out. Others see the damage but do not understand the risk. This can lead to repeated use of containers that should already be thrown away. Reading the labels on plastic containers is very important. These labels show how the container should be used. Some symbols tell you if the container is safe for the microwave. Others show if it can go in the dishwasher.
Authorities give clear advice on when to stop using plastic containers. If white marks appear on the surface the container should be discarded. Virtanen explains that plastic can be damaged by friction. High heat can also weaken it. Microwave use is a common cause.
White Spots
Food can reach very high temperatures in a microwave. Sometimes it goes beyond what the plastic can handle. When that happens white spots may appear. According to Virtanen these marks are signs of overheating.
Not all plastics are the same. Each type has its own heat limit. You should only microwave containers that are clearly marked as microwave safe. If there is no such marking you should not place the container in the microwave at all.
Damaged plastic can release chemicals and microplastics into food. This happens when food touches the weakened surface. Using a damaged container once is unlikely to cause harm. Using it again and again is not a good idea.
The Finnish Food Authority also advises against reusing food packaging like ice cream tubs. These items are only tested for their original purpose. They are not made for long term food storage. Chemicals can move into the food stored inside them. Being careful with plastic containers is a small step that can protect your health over time.
