Are you a fan of Tupperware? Be careful, although they are very practical, they are not necessarily harmless. Here are the signs of wear and tear to watch out for to protect your health.
Light and durable, they populate our refrigerators in search of food to preserve. These accessories are Tupperware – funny, colorful boxes that make our daily lives in the kitchen easier. But if their advantages are no longer to be proven, they can also prove dangerous. Explanations.
If the Tupperware is cracked or scratched
According to statements by Andrea de Vizcaya Ruiz, associate professor of environmental and occupational health at the University of California Irvine, to the Verywell health site, if the boxes are damaged (cracks, scratches, chips, etc.), they must be removed. side. Not only do they become more difficult to clean, but above all they no longer protect food from external bacteria.
If the box is stained or smelly
If the Tupperware is stained and smelly, be careful. Malodorous odors and/or persistent stains may indicate the presence of residual bacteria, which can alter the taste of food or even contaminate it.
If the box no longer closes
The other sign that should alert you? A box that no longer closes properly. And for good reason: a box that is no longer waterproof does not properly maintain the freshness of the food, which can then deteriorate more quickly. Here too, the risk of spreading bacteria is therefore significant.
If the Tupperware has heated in the microwave
Finally, beware of the plastic box that gets lost in the microwave. Tupperware is not meant to be heated, as heat deteriorates the plastic… which can then release microplastics. Harmful substances (phthalates and potentially bisphenol A) can then pass directly into food.
It is therefore better to avoid heating your boxes, even if the container seems robust and of good quality.
