It is important to underline how the laws considered up
until now are based on the results of scientific research
aimed at determining the incidence of any possible release
of materials to food.
As a matter of fact, the legislation often sets a general principle
that can only be assessed scientifically for each material.

The interest shown with regards to the release of various materials which come into contact with food
has involved theWHO and the Scientific Committee of the Council of Europe at the international
level, and the ISS (Higher Institute of Health) in Italy.
TheWHO, in cooperation with the FAO, have carried out several studies aimed at setting the limits
for daily ingestion of different materials. In their laboratories,The Higher Institute of Health and the
Scientific Committee of the Council of Europe subsequently assessed the potential average intake
caused by using saucepans made of certain materials, also taking into consideration that
many substances are present in nature and are therefore found in the everyday diet, i.e. in foods
themselves.
The cases considered allowed the assessment of whether or not the release of these materials to food
could be risky for the health.The results obtained are listed in a technical document named Guidelines
on Metals and Alloys Used as Food Contact Materials.
Many international organizations have developed specific research in the last decades with regards to
the hygienic safety of the materials which come into contact with food.
The American Food and Drug Administration, one of the most stringent ruling bodies in the world,
has set limits only for certain materials.
According to the FDA, there are no alarming levels of release from aluminum containers, seeing as it
is an element present in food such as strawberries, water, and cereals. It has also been noted that some
drugs, i.e. antacids, contain sensitive quantities of aluminum. Nevertheless the levels of intake which
may be dangerous to human health have not yet been determined.
Anti-adherent coatings are considered safe since they are inert.Tin-coated copper has also not been
considered capable of causing significant release to foods.As to stainless steel, whose release values
are extremely low, it has been ascertained that the surface can be easily damaged by salt.

The table below contains the values
of daily intake of some materials
compared with the tolerance limits
set by theWHO (for an individual
weighing 60 kg). Please note
that 90% of the value relevant to
aluminum intake (6 mg) derives from
diet while only a minimum
part is due to contact with saucepans.
