Silicone molds are sometimes preferred by consumers, as they are considered more practical.
However, according to a study by UFC-Que Choisir, a large part of these utensils are likely to contaminate food with “very high” levels of harmful substances.
Of 29 mussels studied, 23 would thus present a health risk.
Contamination reinforced by cooking
“These are substances which are considered by the European authorities as extremely worrying”, explained to Franceinfo Olivier Andrault, food mission manager within the consumer defense association.
He cites, for example, the cases of the Carrefour Home and AliExpress moulds.
These contaminations are reinforced by successive cooking and the use of fats.
"Fifteen times more substances are emitted during the third firing than during the first", explains Olivier Andrault about a Tupperware brand mould.
Health hazards?
"An increased risk of cancer, genetic mutations, damage to reproductive functions", lists Olivier Andrault.
The project manager indicates, however, that it is exposure to a whole range of harmful substances in daily life that increases this risk in some people, and not just the use of silicone molds therefore.
#silicone molds: our test reveals worrying results with too much migration of harmful substances to food.
The @UFCquechoisir calls for strict #EU regulations and seizes the @dgccrf for tighter controls.

“Obsolete” regulations
Although these substances are recognized as harmful, no clear ban has been formulated by the authorities.
At the French level, the regulations are “obsolete” in the eyes of Olivier Andrault because they “do not define a maximum migration, that is to say a limit for the substances of most concern”.
In addition, the free movement of goods at European level would facilitate the arrival of products subject to more lax regulations.
The UFC-Que Choisir study still points to good students.
Ikea or Tefal molds would thus be much less harmful.
For the others, the association calls for a referral to the repression of fraud (DGCCRF) for a strengthening of controls and calls on the European Commission to put in place more protective regulations for consumers.
