Be Careful with Bamboo Tableware

fashionable but not superficial, bamboo-based cooking utensil or tableware could release toxic substances into your food. Since glasses, salad lawn bowling and early credit card kitchenware are no long democratic, it is tempting to go for their “ natural ” versions, in particular based on bamboo .
however, in late months, more than a twelve recalls have concerned childcare articles ( sets of plates and glasses ), picnic tableware, “ lunch boxes ” and others .
At the lineage of these reminders, the Fraud Repression ( DGCCRF ) points, in about all cases, a “ migration of components [ to ] food ” and a “ chemical risk ”. Bad surprise…

Knowing that bamboo is a establish, not a wood, this impacts the manufacture of the material. “ While wood can be a singular material, for example cut into the form of a spoon or salad bowl, bamboo is used in the shape of fibers or powder, needing to be agglomerated, ” explains Anne Lafourcade, environmental health engineer .

Toxic Components for the kidneys or carcinogenic

As a binder, manufacturers most often use a fictile melamine-formaldehyde resin – what is normally called “ melamine ” .
This resin is normally harmless .
But in case of hapless timbre, it releases its components into food .
however, beyond the empower migration thresholds, melamine can be toxic to the kidneys, and formaldehyde is recognized as carcinogenic .

Abnormalities affecting more than one in ten bamboo objects

In 2013, a DGCCRF survey of manufacturers, importers and distributors of wooden and bamboo objects found an anomaly pace of 13.8 % for bamboo objects alone, “ with for example the migration of formaldehyde ” .
Since last year, the countries of the European Union, including France, have increased their controls on “ unconventional plastics ” products such as melamine bamboo .

In question, a poorly controlled manufacturing process

The results are rather concern : “ For the same object, we observe very variable migration rates from one batch to another ”, explains Pascale Lambert, food touch expert at the SGS lab in Rouen. The latter published an alert last July on products made from bamboo roughage and melamine .
But why such variability ? “ There is a inadequate command of the fabricate process, ” continues the adept. As the assortment of bamboo powder and melamine is not homogeneous, the latter remains partially free and frankincense “ escapes ” from the material. »

On the regulatory side, bamboo is fuzzy

however, there are no regulations governing bamboo gunpowder – nor european regulation newton ° 1935/2004 on materials and objects placed in contact with foodstuffs, nor more specific textbook on materials such as plastics or others .
In the diagnose of the precautionary principle, shouldn ’ t we ban the sale of bamboo tableware ? Some member countries of the Union, such as Austria, have done sol .
France could draw inhalation from this… In the interim, prefer glass, stainless steel, porcelain or even polypropylene containers .

Beware of microwave heating!

pure or mix with other substances, melamine does not tolerate hotness well : it releases toxic molecules such as formaldehyde .
prohibition, therefore, to heat melamine-coated bamboo dishes in the microwave .
even bamboo mugs are on the hot seat : the tests conducted by the german Federal Institute for Risk Assessment ( BfR ) on 228 types of bamboo cups bear witness to this.

With liquids above 70 ° C, the European limit values ​​for migration of toxic substances were exceeded in 35 % of cases. What ’ s more, the total of melamine released increases with exposure to hot or slightly acidic liquids like sodas .
